VECHANICS OF D. 5. 73.8% THERMAL STRESS Steel Rod d = 20 mm L = 5 m E = 200 GPa a = 11.70 µm/(m-°C) p = 8,000 kg/m³ 1. A steel rod is positioned vertically as shown in the figure. It is fixed at one end and unsupported at the other end. An external force (F = 800 N) is applied to the free end of the rod the same time when the temperature is raised by 25 C. Assume that all deformations will happen at the same time, compute the stress developed in the steel rod if the gap between the free end of the steel rod and the ground is 0.20 mm. %3D GAP
