The block of weight W = 100 Ib is suspended by two springs each of stiffness k = 200 Ib/ft and is acted upon by the force where t is the time in seconds. Determine the amplitude X of the steady-state motion if the viscous damping coefficient c is (a) 0 and (b) Compare these amplitudes to the static spring deflection
