Question

The bell-crank mechanism is in equilibrium for an applied load of F1 = 17 kN applied at A. Assume a = 300mm, b = 190mm, c = 85mm, and θ = 50°. Pin B is in a double-shear connection and has a diameter of 30 mm. The bell crank has a thickness of 32 mm. Determine

(a) the shear stress in pin B.
(b) the bearing stress in the bell crank at B.

The bell-crank mechanism is in equilibrium for an applied load of F1 = 17 kN applied at A. Assume a = 300mm, b = 190mm, c = 85mm, and e = 50°. Pin B is in a double-shear connection and has a diameter of 30 mm. The bell crank has a thickness of 32 mm. Determine (a) the shear stress in pin B. (b) the bearing stress in the bell crank at B. Bell crank Support bracket B a Answers: Tpin B= i MPа Ob = i MPa
