摘要: Every hitter knows that there is a spot on the fat part of baseball bat where maximum power transferred to ball when hit. Why isn’t this at end bat? A simple explanation based torque might seem identify as sweet spot, but known be empirically incorrect. This paper develops model helps explain empirical finding. We consider outputs greatest hit speed. Firstly, we simplified collision between and free model, applying laws classical dynamics find position spot. According rules game, chose parameters used Maple 13.0 do calculation plotting successfully. also augments confirm or deny effect predict different behavior for wood metal bats. found “corking” affects extents due size hole density substance filled, which confirming reasonability MLB, argued competitions should always set such kinds rules.
