What distance a power hitter gains using a lighter corked bat he loses in collision efficiency. But a singles hitter may get solid contact more often with the lighter, illegal bat. Steve Mirsky reports
強力的擊球手用軟木填塞球棍得到的那點更遠的距離,由于碰撞效率的問題而被失去了。 但是,用這種輕的違規(guī)的球棍,一壘安打手可能會更多地穩(wěn)穩(wěn)擊中球心。Steve Mirsky報道
Baseball players sometimes cheat! One popular method has been to cork the bat. You drill out some of the core of the bat, and replace the heavy wood with light cork. You can then swing the lighter bat faster, and thus hit the ball further.
Of course, most ballplayers aren’t physicists, so they don’t realize that by making the bat lighter, they’re reducing the collision efficiency. You swing faster, but get a limper contact. In theory, anyway.
So physicists led by the University of Illinois’s Alan Nathan tested corked bats under controlled conditions. The doctored lumber actually usually causes the ball to go less far, they found. The work appears in the online forum the Physics arXiv. [http://bit.ly/9At1lX] So for a power hitter to cork his bat is a bad idea.
But the researchers note that, ironically, a corked bat might result in more homers from non-homer hitters. Who can watch a pitch slightly longer before swinging, make up for the lost time with a faster swing and achieve more solid contact more often. So a corked bat is a bad idea for Sammy Sosa, who got caught using one. But a good idea for, say, Bucky Dent.
