The 50mm diameter cylinder is made from Am 1004-T61 magnesium (E = 44.7GPa, a = 26x10^-6/°C)
and is placed in the clamp when the temperature is T1 = 15°C. If the two 304-stainless-steel (E =
193GPa, a = 17x10^-6/°C) carriage bolts of the clamp each have a diameter of 10mm, and they hold
the cylinder snug with a negligible force against the rigid jaws, determine the temperature at which
the average normal stress in either the magnesium or steel becomes 12 MPa.
