Question

A steel rod with a length of l = 1.55 m and a cross section of A = 3.80 cm2 is held fixed at the end points of the rod. What is the size of the force developing inside the steel rod when its temperature is raised by ∆T = 25.0 K? The coefficient of linear expansion for steel is α = 1.17×10-5 1/K, and the Young modulus of steel is E = 200.0 GPa.
