Member (1) is a solid 50 mm diameter cylinder made from magnesium. The modulus of elasticity is 44.7 GPa and the thermal coefficient of expansion is 26 x 106/°C. The cylinder is placed in a clamp when the temperature is 20℃ Two stainless steel carriage bolts (2) hold the cylinder snug with negligible force against the rigid jaws of the clamp. Each bolt has a diameter of 10 mm, modulus of elasticity of 193 GPa, and a coefficient of thermal...

A 10-m steel rod is snugly supported by two rigid supports at
the end. The coefficient of thermal expansion and contraction of
the rod is 6X10^-6 per F and the elastic modulus is 210 GPa. If the
temperature of the body is increased by 50 F, the thermal stress
developed at the supports is most nearly:
