A steel rod of 15- mm diameter is held snugly (but without any initial stresses) between rigid walls by the arrangement shown in the figure part (a). (For the steel rod, use α = 12 x 10-6/˚C and E = 200 GPa.) Calculate the temperature drop ΔT (degrees Celsius) at which the average shear stress in the 12 – mm diameter bolt becomes 45 MPa. Also, what is the normal stress in the rod? What are the average bearing stresses in the bolt and clevis at A and between the washer (dW = 20mm) and wall (t = 18 mm) at B?
