The equilibrium position of the mass m occurs where y = 0 and y B = 0.

Question:

The equilibrium position of the mass m occurs where y = 0 and yB = 0. When the attachment B is given a steady vertical motion yB = b sin wt, the mass m will acquire a steady vertical oscillation. Derive the differential equation of motion for m and specify the circular frequency wc for which the oscillations of m tend to become excessively large. The stiffness of the spring is k, and the mass and friction of the pulley are negligible.
