PROBLEM 10.73 Using the method of Section 10.8, solve Problem 10.39. Determine whether the equilibrium is stable, unstable or neutral. (Hint:The potential energy corresponding to the couple exerted by a torsional spring is 21,2Kθwhere Kis the torsional spring constant and is the angle of twist.) SOLUTION Potential Energy 21sin2VKPl=−cosdVKPld22sindVld=+Equilibrium:0: cosdVKdPl==For 400 lb,
