(Solution Download) A steel rod of 15-mm diameter is held snugly (but without any initial stresses) between rigid walls.


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. (For the steel rod, use
12 106/°C and E 200 GPa.)
(a) Calculate the temperature dropT (degrees
Celsius) at which the average shear stress in the 12-mm
diameter bolt becomes 45 MPa.
(b) What are the average bearing stresses in the bolt
and clevis at A and the washer (dw 20 mm) and wall
(t 18mm) at B?
