The uniform link AB has a mass m, and its left end A travels freely in the fixed horizontal slot. End B is attached to the vertical plunger, which compresses the spring as B falls. The spring would be uncompressed at the position 0 = 0. Determine the angle for equilibrium (other than the impossible position corresponding to 0 = 90°) and designate the condition which will ensure stability.
