4) If a bronze model railroad track is 26 in. long and the ends are restrained from moving when
the temperature rises 40 °F, what is the stress that results? (Look up the coefficient of
thermal expansion and modulus of elasticity.)

Expert Solution
Step 1

Given:-

         Length of the bronze model track = 26 in

                                    Temperature rise = 40° F

       coefficient of thermal expansion α = 18×10-6 I° F

           Elasticity modulus of copper  E = 110×103 ksi
