A student foolishly attempts to stop a steel bar, of length L = 1 m and at a temperature of 20ºC, from thermally expanding by attaching it to a wooden support with a nail at each end. Steel's Young's modulus is Y = 1.9 × 1011 N/m2 and it's linear thermal expansion coefficient is α = 12.4 × 10-6 1/C.Randomized VariablesY = 1.9 × 1011 N/m2α = 12.4 × 10-6 1/C
