The uniform bar AB has weight W. If the attached spring is unstretched when = 90
Question:
The uniform bar AB has weight W. If the attached spring is unstretched when θ = 90 deg, use the principle of potential energy and determine the angle θ for equilibrium. Investigate the stability of the equilibrium positions. Note that the spring always remains in the vertical position due to the roller guide.
Given:
W = 10 lb
K = 5 1b/ft
a = 4 ft
