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:
