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 method of virtual work and determine the angle θ for equilibrium.
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
