A steel rod 15mm diameter is held snugly (but without any initial stresses) between rigid walls by the arrangement shown in the figure. (For the steel rod, use α= 12 x 10^-6 per deg. Celsius and E= 200GPa). a. Calculate the temperature drop (delta T) in degree Celsius at which the average shear stress in the 12mm diameter bolt becomes 55MPa. b. What ar ethe average bearing stresses in the bolt and clevis at A and the washer (dw = 20mm) and wall (t= 18mm) at B?

Question
A steel rod 15mm diameter is held snugly (but without any initial stresses) between rigid walls by the
arrangement shown in the figure. (For the steel rod, use α= 12 x 10^-6 per deg. Celsius and E= 200GPa).
a. Calculate the temperature drop (delta T) in degree Celsius at which the average shear stress in the
12mm diameter bolt becomes 55MPa.
b. What ar ethe average bearing stresses in the bolt and clevis at A and the washer (dw = 20mm) and
wall (t= 18mm) at B?
