The 0.35-inch-diameter cylinder is made from C83400 red brass and is placed in the device depicted below when temperature is T1 = 5 oF throughout. The two Am 1004-T-61 magnesium alloy carriage bolts each have a diameter of 0.10 inches and hold the cylinder snug with negligible force against the rigid jaws. Determine the maximum temperature (in oF) that the brass cylinder can be subjected to without causing yielding of any one of the materials. The end plates will not deform or fail.
An engineering machine component operating in a high temperature environment consists of a copper pipe having a cross-sectional area of 2 000 mm2 and 0.3 m long, which is placed between two rigid caps. Four M22 steel bolts are symmetrically arranged around the tube and parallel to the axis of the tube and are lightly tightened. 3.1 Find the stress in the pipe and the bolts if the temperature of the assembly is increased from 25 0C to 95 0C. 3.2 What load will each bolt carry at the raised temperature? 3.3 Make a neat sketch of the assembly.
