In baseball, bats made of metal are designed to perform like bats made of wood. To test how similarly they actually perform, both types of bats were used by hitters in a batting cage off of a pitching machine. The pitching machine's velocity could be adjusted as needed. A radar gun was used to measure the velocity of a batted baseball. The exiting velocities of balls hit with metal and wood bats were compared. The natural bending modes were also analyzed to compare the size of each sweet spot. It was discovered that when missing the sweet spot the bats performed similarly, but, when the sweet spot was hit, the metal bat performed significantly better.
