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.
