Unformatted text preview: PROBLEM 10.8 The two-bar linkage shown is supported by a pin and bracket at B and a collar at D that slides freely on a vertical rod. Determine the force P required to maintain the equilibrium of the linkage. SOLUTION Assume Have Since bar CD moves in translation yA yC = 160 yA 320 or yC = 1 yA 2 yE = yF = yC or Virtual Work: y E = yF = 1 yA 2 U = 0: - P y A + ( 400 N ) yE + ( 600 N ) yF = 0 1 1 - P y A + ( 400 N ) y A + ( 600 N ) y A = 0 2 2 or P = 500 N P = 500 N ...
