A threaded steel rod (E=210 GPa, dr = 15mm, linear coefficient of expansion= 12x10-6/ 0C) is held stress-free between rigid walls by a nut and washer (dw = 22mm) assembly at each end. If the allowable bearing stress between the washer and the wall is 55 MPa and the allowable normal stress in the rod is 90MPa, determine the maximum permissible temperature drop.

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.
