The bell-crank mechanism is in equilibrium for an applied load of F1 = 11 kN applied at A. Assume a = 250mm, b = 100mm, c = 90mm, and θ = 40°. Pin B is in a double-shear connection and has a diameter of 29 mm. The bell crank has a thickness of 31 mm. Determine the shear stress in pin B. and the the bearing stress in the bell crank at B.

The d = 14-mm-diameter solid rod passes through a D = 19-mm-diameter hole in the support plate. When a load Pis applied to the rod, the rod head rests on the support plate. The support plate has a thickness of b = 11 mm. The rod head has a diameter of a = 28 mm, and the head has a thickness of t = 8 mm. The shear stress in the rod head cannot exceed 130 MPa, the punching shear stress in the support plate cannot exceed 95 MPa, and the bearing stress between the rod head and the support plate cannot exceed 125 MPa. Determine the maximum value of Pmax that can be supported by the structure. Support Plate - Hole diameter D Rod Нead b -

Two loads P act as shown, one parallel to (x0) and another parallel to z0; each load P equals 2.5 kN. The crankshaft dimensions are b1 = 80 mm, b2 = 135 mm, and b3 = 55 mm. The diameter of the upper shaft is d = 26 mm. Determine the normal stress at point B, which is located on the surface of the upper shaft at the yo axis.
