Question

A machine part is undergoing Simple Harmonic Motion with a frequency of 5.10 Hz and amplitude 1.80 cm.

(a) Determine the angular velocity “ω” of the oscillation.  

(b)      What is the displacement of this oscillation at t=5 sec if it follows the part of x=A cos (ωt) with x=0 m at equilibrium?

Answer 1

(1) frequency and amplitude of SHM is given as;

solution:

(A) Angular velocity can be defined as;

(B) displacement of this oscillation is given as;

at t = 5 s;
