Question

Calculate (a) the magnification factor (b) the amplitude of the steady state response and (c) state if the steady state response is in phase or out of phase for

(1) P19.18 if a vertical (downward) force of P=4 sin(20t) (lb) is applied to the 75lb block

A 75-lb block is supported by the spring arrangement shown. The block is moved

vertically downward from its equilibrium position and released. Knowing that the

amplitude of the resulting motion is 2 in., determine (a) the period and frequency

of the motion, (b) the maximum velocity and maximum acceleration of the block
