The block of weight W = 100 lb is suspended by two springs each of stiffness k
Question:
The block of weight W = 100 lb is suspended by two springs each of stiffness k = 200 lb/ft and is acted upon by the force F = 75 cos 15t lb where t is the time in seconds. Determine the amplitude X of the steadystate motion if the viscous damping coefficient c is (a) 0 and (b) 60 lbsec/ft. Compare these amplitudes to the static spring deflection δ_{st}.
