What Paul Nyman's Experiments Were About

For obvious reasons, he would not use the word “torque.” However, there is no force he could apply, other than torque (top-hand driving forward – bottom-hand pulling rearward), that could snap the handle after the bat made contact with the bag.

Hi Jack,

I agree with JJA; one cannot "read into an experiment" too much without running into problems. Jack, I checked GSM's quote, and then visited Nyman's site. According to Nyman, the faster the one swings, the more energy that is being used; the more energy that is being expended, the faster the bag accelerates. Following scientific logic, the greater the acceleration, the harder the bat will hit the bag at impact. This means that 45 mph batspeed will hit the bag with less energy (and less vibration) than 75 mph batspeed.

For example, in crash tests, cars crashing into an object 15 mph might have fender damage, whereas cars crashing into an object 100 mph will be totaled.

Best,

P.S. Jack, I mean no disrespect whatsoever--I am just trying to clarify what is actually said on Paul Nyman's site.
