Forced oscillation

Question

In forced oscillations displacement equation is $\large x\left( t \right)\, = \,A\cos \left( {{\omega _d}t + \theta } \right)$ then amplitude ‘A’ vary with forced angular frequency $\large {\omega _d}$ and natural angular frequency ‘ $\large \omega$ ’ as (b = damping constant)

Easy

A

$\large \frac{F}{{m{\omega ^2}}}$
B
C

$\large \frac{F}{{m\left( {{\omega ^2} - \omega _d^2} \right)}}$
D

Solution

The amplitude "A" is a funciton of the external periodic force frequency and the natural frequency $\large {\omega _o}$
