- 600 lb 600 lb An aluminum rod to be used in an aircraft control system is required to stretch 0.12 in. when a 600-1b tensile load is applied to it. If E = 10.2 × 10³ ksi and the allowable stress is 17 ksi, determine the smallest diameter that can be selected for the rod and the corresponding required length of the rod.arrow_forwardThe 3/4-in.-diameter shaft is subjected to the loading shown. Determine the stress components at point A. Sketch the results on a volume element located at this point. The journal bearing at C can exert only force components Cyand Cz on the shaft, and the thrust bearing at D can exert force components Dx, Dy, and Dz on the shaft.arrow_forwardRods AC and BC are used to suspend the 200-kg mass.
