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 2 1 , 2 K θ where K is the torsional spring constant and is the angle of twist.) SOLUTION Potential Energy 2 1 sin 2 VKP l =− cos dV KP l d 2 2 sin dV l d =+ Equilibrium: 0: cos dV K dP l == For 400 lb,
