An aluminium rod 20 mm in diameter is screwed at the ends and passes through a 25 mm bore steel tube 3 mm thick. Rigid washers and nuts are the fitted to the screwed ends of the aluminium rod and the whole system heated to 140°C, when the nuts on the rod are lightly tightened to take up any slack. Calculate the stress in the rod and tube when the assembly has cooled to 20°C. (EST = 200 GPa; EAL = 70 GPa; asr = 12 x 10-6 /°C; aAL. = 23 x 10-6 /°C)

An elevated jogging track is supported at intervals by a wood beam AB (L = 7.5 ft) that is pinned at A and supported by steel rod BC and a steel washer at B. Both the rod (dBC= 3/16 in.) and the washer (dB= 1.0 in.) were designed using a rod tension force of TBC=415 lb. The rod was sized using a factor of safely of 3 against reaching the ultimate stress tru— 60 ksi. An allowable bearing stress sba= 565 psi was used to size the washer at B.
