Finding and understanding the sweet spot on a wooden bat.

When you strike a bat against a ball it sends vibrations, much like the vibrations acting on airplanes or bridges, which travel in waves through the bat. This motion is important to understand because every vibration the bat experiences takes energy away from the ball's speed as it leaves the bat.

If you hit the ball at a bat's "nodes", the frequencies (each bat vibrates at several low and high frequencies at once, which is like the harmonics of stringed instruments) cancel out and since this happens you don't feel the sting in your hands that you experience when you hit the ball at different points on the bat.

There is some discrepency of where the sweet spot is on the bat. Some believe that the sweet spot is 17 inches from the end and others believe that it is 6 inches from the end. For a wooden bat, I tend to believe that the sweet spot is 6 inches from the end of a 34 inch bat (opposite of where your hands are). This is due to the fact that if you were to hit a ball 17 inches from the end, you would be hitting on the bat's emblem. If hit hard enough, the bat would break because this is a weak spot in the bat due to the stamping of the emblem.
