Question

4-81. The 50-mm-diameter cylinder is made from Am 1004-T61 magnesium and is placed in the clamp when the temperature is $T_1 = 20^\circ C$. If the 304-stainless-steel carriage bolts of the clamp each have a diameter of 10 mm, and they hold the cylinder snug with negligible force against the rigid jaws, determine the force in the cylinder when the temperature rises to $T_2 = 130^\circ C$. 4-82. The 50-mm-diameter cylinder is made from Am 1004- T61 magnesium and is placed in the clamp when the temp- erature is $T_1 = 15^\circ C$. If the two 304-stainless-steel carriage bolts of the clamp each have a diameter of 10 mm, and they hold the cylinder snug with negligible force against the rigid jaws, determine the temperature at which the average normal stress in either the magnesium or the steel first becomes 12 MPa.

4-81. The 50-mm-diameter cylinder is made from Am
1004-T61 magnesium and is placed in the clamp when the
temperature is T1 = 20^∘ C. If the 304-stainless-steel carriage
bolts of the clamp each have a diameter of 10 mm, and they
hold the cylinder snug with negligible force against the
rigid jaws, determine the force in the cylinder when the
temperature rises to T2 = 130^∘ C.
