22-63. The spring system is connected to a crosshead that oscillates vertically when the wheel rotates with a constant angular velocity of w. If the amplitude of the steady-state vibration is observed to be 400 mm, and the springs each have a stiffness of k = 2500 N/m, determine the two possible values of w at which the wheel must rotate. The block has a mass of 50 kg.
