The bell-crank mechanism is in equilibrium for an applied load of F₁ = 13 kN applied at A. Assume a = 310mm, b = 190mm, c = 70mm, and 0 = 40°. Pin B is in a double- shear connection and has a diameter of 23 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.
