Question

Assume that the allowable stress is the limiting factor. Calculate the minimum required diameter for the rod so as to not exceed the allowable stress. A steel (E = 207

GPa] tension member is being designed for an automobile. It must withstand a load of 3800 N and not elongate more than 0.11 mm in its 610-mm length. The yield strength of the steel is 440 MPa, and a factor of safety of 6.7 is specified with respect to yield. Compute the minimum required diameter of a round rod to satisfy these requirements. Assume that the elongation is the limiting factor. Calculate the minimum required diameter for the rod so as to not exceed the allowable elongation. Determine the minimum required diameter of the rod, so that neither the allowable stress nor the allowable elongation are exceeded.
