Question

A steel rod. of 15-mm diameter is held snugly (but without am1
initial stresses) between rigid walls by the arrangement shown in the figure part a. (For the steel rod, use a = 12 X KT 6 fX and E = 200 GPa.)
(a) Calculate the temperature drop AT (degrees Celsius) al which the average shear stress in the 12-mm diameter bolt becomes 45 MPa. Also, what is the normal stress in the rod?
(b) What are the average bearing stresses in the bolt and clevis al A and between the washer {dw= 20 mm) and wall (r = IS mm) at £?
(c) If the connection to the wall at B is changed to an end plate with two bolts (see figure part b), what is the required diameter dhof each bolt if the temperature drop is A J" = 38°C and the allowable bolt stress is 90 MPa?
