The mode shape of a baseball or softball bat is a simple flexing bending shape that has parts that move and parts that don't. Every bat has a point about seven inches in from the tip of the bat that doesn't move, that doesn't vibrate, called a node. << (function() { 10 0 obj Joe Jackson, a shoeless man, would prefer a custom-built bat known as Black Betsy. Necessary cookies are absolutely essential for the website to function properly. A similar question: The bumper on a pool table is at a height so that the pool ball does not skid when it hits it. I tossed a 12 inch softball at very low speed and filmed the result, using two hands instead of one to increase the spin rate and to make sure the spin axis was horizontal. Washington State University Sports Science Laboratory, You can get into the real nitty gritty of the science of MOI including complex equations by clicking through to the complete Bat-Ball Science Mass Moment of Inertia article, but well put it in laymans terms. It was found, by measuring the frequencies of lots of aluminum tubes (see photo) that the frequency is directly proportional to the wall thickness and inversely proportional to the tube diameter squared. >> A baseball bat is typically between 30-34 inches in length and can weigh anywhere from 24-30 ounces. James Sherwood has a similar site http://m-5.eng.uml.edu/umlbrc describing test procedures used to certify baseball bats and balls at the University of Massachusetts Lowell. >> In addition to the second law, we can understand how the force of the bat affects a balls motion. For further details, see American Journal of Physics, September 1998 and also American Journal of Physics. Only a small fraction of that huge force gets back to the handle to trouble the batter. But I would expect there to be a difference.. Ash bats, on the other hand, are more flexible, making them perfect for contact hitters. /N 15 0 R Thats the sweet spot. There is a greater amount of strength required to swing a wood bat, but the ball exits faster when hit. Regardless of age, the weight of the right handers bat is crucial. The COR for a collision between the bat and the ball is less than 0.59 when energy is lost to vibrations, but can be greater than 0.59 if the bat has a trampoline effect on the ball. Preliminary In order to indicate the origin of the baseball bats problem, the following preliminary are worth mentioning. Popular Science 71.6K subscribers Subscribe 162 19K views 4 years ago Where is the sweet spot on a baseball bat and how do you find it? on: function(evt, cb) { The vibration modes of a baseball bat are easily determined,3-5at least for a freely suspended bat ~e.g., one that is suspended by a light string!. White ash, sugar maple, true hickory, yellow birch, red oak, and Japanese ash are the six wood types that can be used in bats in Major League Baseball. Near the end of the swing, the batter needs to exert a large negative couple on the bat, otherwise the bat will swing around too fast and strike the ball when it is aligned at the wrong angle. by Jessy Williamson | Mar 29, 2023 | Equipment. This cookie is set by GDPR Cookie Consent plugin. The effect is known as the "trampoline effect". Check out Sniper Skin's easy to install, weatherproof and dural bat grips here! This cookie is set by GDPR Cookie Consent plugin. Bud Hillerich, an apprentice woodworker in Louisville, Kentucky, began making Louisville Slugger bats in 1884. This makes the game easier to pick up and more exciting to watch otherwise, every hit would only be a single. However. It is critical not only for the sake of performance, but also for the sake of safety. The flight of a ball through the air depends strongly on how fast it spins, and in what direction it spins. That is, a large fraction of the stored elastic energy in the wall is retained as vibrational energy in the bat. For example, a 33-inch bat with a -3 rating weighs 30 ounces. Taking the rotation rate as 3/8 revolution / 0.04 sec gives 9.4 revolutions / sec or 560 rpm. Physicist Daniel A. Russell explains the physics of a baseball swing with a bat. The sound made by a bat can be described as a "ping". If the ball is at rest (when striking a ball off a T ) then. To view the purposes they believe they have legitimate interest for, or to object to this data processing use the vendor list link below. It is not easy to find information on the actual rate of spin of a softball in flight, but it is relatively easy to measure, at least at low ball speeds and low spin speeds. 6 0 obj See, the trouble with wood is that it vibrates. These cookies track visitors across websites and collect information to provide customized ads. /F 3 0 R Another simple estimate of spin rate is to throw the ball and catch it with the other hand as soon as it is released. >> What two factors determine the location of a baseball bat sweet spot? Since little of the bats energy is lost to vibrations when this spot is hit, more can go to the ball. The ball will rotate about 1/2 a revolution from the initial grip to the release point, in about 0.1 sec or less. Both papers can be downloaded. In the late 1990s, the Crisco-Greenwald Cage Study found that bats made out of materials like aluminum perform better, for a number of reasons: First of all, it takes more skill. In bats made of maple wood, like the Axe Bat, it's easy to find the strongest grain. R. Cross, Physics of Baseball & Softball, DOI 10.1007/978-1-4419-8113-4 14, c Springer Science+Business . { Whenever an object is struck, it vibrates in response. Pitching Trajectories.- 5. << The tube wall is thinnest, stretchiest, and tapered before being rolled, and then the handle is formed. So grab your bat and lets dive into the science behind the swing! Those two are usually close, but theyre not exactly the same. The various supposed sweet spots effectively add up to a sweet zone, about two inches wide, right on the meat of the bat. The sweet spot is found on only one side of the bat. According to Newtons third law, every action has an equal and opposite reaction. For those of us not trying to make it to the majors, using a wooden bat is mostly just a reminder that hitting a baseball is either painful or frustrating, depending on whether youve made contact with the ball or not. Hitting on the sweet spot ensures you dont lose any more energy to making vibrations inside the bat. It is almost as easy as walking. By maintaining the same swing speed with a heavier bat, players can increase bat speed and distance in the same manner. stream When a batter hits a ball, the bat will rebound from the force of the collision. Jessy is an avid baseball fan and writer for the popular website, Baseball Writes. Physics of Baseball & Softball R. Cross Published 22 February 2011 Physics, Education Preface.- 1. /P 11 0 R /WhitePoint [0.9505 1 1.089] /N 6 0 R That said, composite and metal bats are still used by younger players who are still developing their skills. PbLSZTLEE(8E@'*1mg_*eTnN*;*'V3+gm-EEetX%;Bo$ur2ss*N`.-!.kG_q6GDD' The impact on a baseball bat is shorter (since the bat and ball are harder or stiffer), about 1 msec. When To Know Its Time To Replace Your Baseball Mitt, Customizing Your Baseball Bag: A Guide To Personalizing Your Equipment. The bat is 84 cm long, and has a mass of 849 gram. Results for a baseball dropped from heights of 1, 5, 10 and 15 cm onto a piezo are shown below. /R [316 73 572 791 ] 18 0 obj /P 17 0 R Published Mar 30, 2018 4:11 PM EDT. << Colloquially, a player who hits the ball solidly is said to have gotten the sweet spot of the bat on the ball. The physics behind this phenomenon involves the transfer of energy from the bat to the ball. If the vibration frequency is less than about 1000 Hz, the end result is that ball comes off the bat at a lower speed than off a wood bat of the same weight and swing weight. The third law explains what happens to a bat when it strikes a ball. Its harder than football, harder than baseball, harder than basketball, harder than hockey or soccer or cycling or skiing or fishing or billiards or any other of the 60 sports we rated. Pitching Mechanics.- 6. The frequency is typically between 1000 Hz and 2500 Hz, meaning that the wall vibrates in and out 1000 to 2500 times in one second. hitting a baseball is either painful or frustrating. << Energy is lost during the collision if the bat vibrates. QuickTime movie files A and B show a baseball bouncing on a block of granite. Current research on the physics and science behind the game of cricket centers on the performance of the batsmen and bowlers. /N 25 0 R >> window.mc4wp = window.mc4wp || { We call the point where a baseball bat has its nodes the sweet spot. Ball Trajectories.- 4. External forces are the only way to redirect the ball according to the first law of motion. Learn how the sweet spot correlates with movement and vibration. This website uses cookies to improve your experience while you navigate through the website. The sweet spot's location for maximizing how far the batted ball travels after being hit can be calculated scientifically. The more general recommendation is that a teams best hitters should be grouped together in the batting order, rather than spread out, as this maximizes the chances of someone being on base when a good hitter comes to bat. I tossed a 12 inch softball at very low speed and filmed the result, using two hands instead of one to increase the spin rate and to make sure the spin axis was horizontal. Since the CM traces out a spiral rather than a circular path, the center of the circle moves, as the bat is swung, along the path traced out by the inner circle of black dots. Elastic behaviour in the horizontal direction can be described by a tangential coefficient of restitution, which is about 0.5 or 0.6 for a superball but only about 0.2 for a baseball on a rigid surface. This is why it is important that baseball bats are made out of a hard material that can maximize the energy transfer while also reducing the risk of injury to the player. Players tend to feel a zing in their hands; often called bat sting. endstream Swinging a Bat.- 7. The impact point 2 cm from the tip of the Easton bat is a dead spot where the ball doesn't bounce at all, so q = 0. 19 0 obj Definition. << A homerun hit right at the sweet spot would sound different than one hit off the target. In this paper, we analyze the effect on the ball-bat model of corking the bat, and investigate the relationship between the sweet spot and different materials. When you hit a ball just right, you've hit it on one of the three "sweet spots" of the bat. For small swings of a pendulum, the incoming and outgoing speed of the pendulum bob is proportional to its horizontal displacement, so the relevant ball speed ratios can be measured directly off the film with a ruler. No player is perfect so all players will miss hitting in the sweet spot, so every hit could result in baseball bat damage. /V 7 0 R So, well hit balls are struck at the sweet spot. A question that is equally interesting is how the swing speed of each body segment varies as the bat speed varies and as the bat swing weight varies. These cookies ensure basic functionalities and security features of the website, anonymously. Largest thickness - The sweet spot Bat - Ball Collision Diagrams Vball 1 = Vb Vbat 1 = V2b V bat 2 = V2a Vball = V1a Before After Bats in the United States are primarily made of aluminum, which accounts for nearly all of them. q varies from about zero near the tip of the bat to about 0.2 or 0.3 further along the barrel, and needs to be measured for any given bat since it is usually too hard to calculate. From that you can work out the speed and spin of the ball before and after it bounces. By combining the results of these two separate experiments, we can then work out what happens when a bat is swung at an incoming ball. A heavier bat is a better choice for hitting faster balls. Allow Dan Russell to explain: Any solid structure has vibrational patterns.. Analytical cookies are used to understand how visitors interact with the website. Most contact and power hitters use maple bats because the material is the strongest and has very little give, which is why they swing ash bats. The effect of the hands on the centre of percussion is described in American Journal of Physics, , 622-630 (2004). >> If the ball is also mounted as a pendulum, the experiment can also be performed in reverse, by swinging the bat at a stationary ball. Sign up to receive Popular Science's emails and get the highlights. Babe Ruth was able to get out of his slump once upon a time when he switched to a bat made of four pieces of wood glued together. The COR for a collision between the bat and the ball is less than 0.59 when energy is lost to vibrations, but can be greater than 0.59 if the bat has a trampoline effect on the ball. You also have the option to opt-out of these cookies. Rather, most coaches and others think in terms of wrist torque, which is probably much too small to provide the necessary large couple near the end of the swing The couple must come mainly from the two arms, not the wrists. He has been writing about the sport for over five years and is passionate about sharing his knowledge and enthusiasm for the game. % The sweet spot is typically located around the center of the bat, and its size varies depending on the type of bat being used. ** A new article on knuckleballs was added in May 2013 **. On average, players aged 15 to 17 hit 140 feet, while players aged 16 to 18 hit 150 feet, and players aged 18 to 19 hit 165 feet. These spots are also described in the physics of tennis page. The ideal is the 110 turn model. For the purposes of this paper, I will attempt to examine the . Explains r. cross, "the sweet spot of a baseball bat," american journal of physics, 66, 772-779. A superball has a COR of about 0.9, a baseball has a COR of about 0.5 and a sorbothane ball has a COR of about 0.1 (ie it hardly bounces at all). /P 14 0 R Although the Hickory bat wood is the most difficult to swing, it is also the most powerful, making it the hardest of all bat wood species. But opting out of some of these cookies may affect your browsing experience. Edd Roush holds the distinction of being the heaviest Major League Baseball player in terms of weight. The collision of a bat and a ball can be understood by treating the bat as a heavy ball whose mass depends on the impact point. Balls compress along the same F vs x curve, regardless of the ball speed, although the actual compression curve for a given ball will depend on its stiffness. The sweet spot classification quantifies that as a batted-ball event with a launch angle ranging from 8 to 32 degrees. << At other impact points, the impact is usually felt as a sting or jarring of the hands and forearm, particularly if the impact occurs at a point well removed from the sweet spot. Is swinging a bat potential or kinetic energy? By understanding the physics of baseball bats, players can maximize their performance on the field. Other research indicates that the 'sweet spot' lies between the nodes of the lowest 2 vibrations of the bat. In theory, this should mean that a homerun hit right on the sweet spot would sound different from an off-target pop fly. A first guess would be at the tip of the bat since the tip travels the fastest. Demonstrating the sweet spot of the bat in a talk I gave at Wrigley Field for University of Illinois alumni in 1997. It is very surprising that no one seems to have worked this out before. Two ounces doesnt seem like much but Ive seen it make a large difference. These vibrations travel in waves up and down the length of the object. But man, hit it right on the sweet spot and it feels like you are a baseball god. The above results are more or less as expected, in that light bats can be swung faster than heavy bats. But strong vibrations are generated for impacts near the tip. A high performance bat has a strong trampoline effect and hence a relatively large COR. /V 13 0 R It minimizes vibration of the bat and results in the maximum energy delivered to the ball, meaning it travels the farthest. Thank you so much for. In recent years, an acoustics professor and engineer, Daniel Russell, from Pennsylvania State University helped develop a Kevlar-based vibration damper to help combat the painful sting of missing the sweet spot (only the physical sting, though). This force is required to change a 5 1/8th-ounce ball from a speed of 90 mph to a speed of 110 mph, this distorts the baseball to half its original diameter and the bat is compressed one fiftieth of its size.. As a result, the fundamental and second vibration modes are both excited with about the same amplitude. The swing weight of the bat (that is, its moment of inertia) can be determined from the measured period of oscillation when swung as a pendulum. The film is shown here, taken at 25 frames/sec. The pain of hitting away from the sweet spot motivates you to learn how to find itthat, or buy a composite bat with a vibration damper in the handle. The majority of wooden bats are made from ash, with maple, hickory, and bamboo following in their footsteps. The tubes were suspended by a length of string so that they could vibrate for a long time without damping. Newtons second law, which deals with the value of time, is also important in baseball. /P 11 0 R gF/(+GaKo$qneLWDrQ#;5\S(\$q'LM9bYJX9N;hHO_e;>`Y"/'J:I~> We and our partners use data for Personalised ads and content, ad and content measurement, audience insights and product development. As the ball leaves the bat, the potential energy is converted into kinetic energy. Hitting a baseball in the sweet spot on a baseball bat gives the best rebound and does not twist the handle of the bat in the hitter's hand. The spot is close to the centre of percussion (COP) for a freely supported bat, so it was thought at one time that the sweet spot might be associated with the COP. >> It is almost as easy as walking. endobj Typical results are shown here for a superball, a baseball and a sorbothane ball. } /R [52 73 308 791 ] The tangential COR is defined in the same way as the normal COR, but in terms of the horizontal speed of the ball at the contact point rather than the normal (ie vertical) speed of the contact point. How much force does a baseball bat generate? The dead spots in the bat will cause a vibration to be sent down through the handle of the bat into the hands, which ultimately causes vibration or a stinging feeling. << Subscribe to get special offers, free giveaways, and once-in-a-lifetime deals. not apply to baseball or softball bats. What have you found works for you? It is not difficult to swing a bat. The batter might find that he needs to change the way he swings the bat if the swing weight is altered, or he might have a grooved swing technique and swing every bat the same way. For most bats all of these "sweetspots" are at different locations on the bat, so one is often forced to define the sweetspot as a region, approximately 5-7 inches from the end of the barrel, where the batted-ball speed is the highest and the sensation in the hands if minimized. Adair provides a few answers in his book The Physics of Baseball but he does not give the directions or the torques. (7Boo^^S:71(MN]ZQX/+Cbu.lK"p74pe1T%s.DY%&\1TdJhr54.M9au6>79n6`Q:4 Additionally, a hard material helps to reduce the amount of vibration that travels through the bat and into the players hands, helping them to maintain control over the bat while swinging. You can actually hear where the sweet spot is just by tapping a bat yourself. Are heavy bats are more powerful than light bats? The hitch is, no one knows for sure how close the optimal spot for hitting is to the sweet spot that players know and love. >> According to Science Daily, human hands are sensitive to vibration frequencies between 200-700 hertz and we experience the most pain when those frequencies are between 600-700 hertz. /V 6 0 R According to Newtons second law of motion, the acceleration of an object equals the net force acting on it divided by its mass, or a = F m . The result was not a super slow softball spin, neither was it particularly fast. The heavier the bat, the higher the bats bat speed. The bat is 84 cm long, and has a mass of 849 gram. Join PopSci+ to read sciences greatest stories. Well also examine the impact that technology has had on the design of baseball bats in recent years and how it has helped players to hit the ball farther and harder. One of these sweet spots relates to vibration. If you are interested in diving deeper into the subject of the science of baseball bats, check out some of these great articles and research: You dont have to be scientist to get a sense of how baseball bats perform. The faster the hit ball travels, the longer it should travel. They have a hoop vibration mode - alongside the typical bending modes - that extends their sweet spots. With each hit, you should hear and feel the vibrations (make it easier by taping a paper cone around the knob, loosely enough that it will vibrate when the bat does). /Gamma [1.8 1.8 1.8] The size and weight of the bat is a matter of personal preference, but it is important to remember that a bat must be approved by the league in order to be used in official games. } In file A, the ball spins faster than in file B, both before and after the bounce. Metal bats, on the other hand, are lighter and more forgiving, but they lack the power of iron bats. Learn how to add this technique to your swing while still keeping a balanced, relaxed approach to the ball. The physics of a baseball bat include the material of the bat, the length, weight, and shape of the bat, and the force of the swing. While the majority of baseball bats are constructed from wood, there are also metal alloy bats available for certain leagues. If the ball didn't bounce at all then COR would be zero. Baseball bats (typically aluminum) are made up of either hardwood or metal. Baseball bats are most commonly made out of wood, such as maple, ash, or bamboo. Finally, if players started using bats made of a better material, the game would become dangerous as the baseball would start travelling much too fast. Basic Physics.- 2. Baseball physics is based on fluid dynamics. My particular research interests are two-fold: the physics of the baseball-bat collision and the flight of the baseball.
