If the driving frequency for the system of Prob.8/47 is ω = 6 red/sec. determine the required value of the damping coefficient if the steady-state amplitude is not to exceed 3 in.
Prob. 47
The 64.4-lb cart is acted upon by the harmonic force shown in the figure. If c = 0 determine the range of the driving frequency ω for which the magnitude of the steady-state response is less than 3 in.
