A steel bolt having 650 mm² cross-sectional area, passes centrally through a copper tube of 1200 mm² cross-sectional area. The tube is 500 mm long and is closed by rigid washers, which are fastened by the threads on the steel bolt. The nut is now tightened by 4 of a turn. If the pitch of the thread is 3 mm, the stresses induced in the tube and the bolt are (Take Es = 2.05 x 10^5 N/mm² and Ec= 1.1 x 10^5 N/mm²) (a) 82.89 N/mm² and 153 N/mm² (b) 81.38 N/mm² and 143 N/mm² (c) 78.82 N/mm² and 185 N/mm² (d) 165 N/mm² and 304.6 N/mm² 2 2 A steel bolt having 650 mm² cross-sectional area, passes centrally through a copper tube of 1200 mm² cross-sectional area.
