The ball is hung on a thread with a length of l = 20cm. Three other balls are hung on strings. The length of one thread of the ball is l = 10cm, of the other l = 20cm, and of the third l = 30 cm.
1. Determine the natural frequencies of mathematical pendulums
2. Divert the ball with length l = 20cm from its equilibrium position and let it vibrate freely. the amolitus with which the other balls begin to vibrate. When vibrating, which of the balls does not have a resonance? (g = 10m /s
Given,
Length of the thread
Now, substituting the values,
Hz
