Baseball players swung very light and very heavy bats through our instrument and the speed of the bat was recorded. These data were used to make mathematical models for each person. Then these models were coupled with equations of physics for bat-ball collisions to compute the Ideal Bat Weight...
Determining ideal baseball bat weights using muscle force-velocity relationships The results of this coupling suggest that some batters use bats that are too heavy for them, and some batters use bats that are too light, but most... AT Bahill,WJ Karnavas - 《Biological Cybernetics》 被引量: ...
But the houses were cold, closed, unfriendly, and I ran on until I heard Jeremy’s screams behind me announcing that our attackers had fled.The neighbors who had not opened their doors to us came out with baseball bats and helped Jeremy find his glasses and keys. In a ...
