Question

The ends of a tuning fork oscillator at a frequency of 440Hz with an amplitude of 0.50mm.determine the maximum velocity and the maximum acceleration of the ends.

Answer 1

assume SHM.

EG:
let \(x = A \cos(\omega t ) \)

\(\dot x = - \omega A \sin(\omega t ) \)

\(\ddot x = - \omega^2 A \cos(\omega t ) \)

\(f = 400 Hz, A = 0.50 mm\)

Finally:

- \(\omega = 2 \pi f\)
