The damper has a coefficient of c= 107 Ns/m, and its mass is negligible. The crank AB has a mass of M = 20 kg and radius of gyration of ko = 0.316 m. The lengths are; a = 0.2 m, and b 0.3 m. The coordinate x is measured from the static equilibrium configuration of mass m = 30 kg. The spring has a stiffness of k = 8 kN/m. If the mass m is displaced upwards by 0.012 m and released from rest, estimate the velocity with which it passes through the static equilibrium configuration for the first time after it is released, by assuming small motion. b E A Hil
