Question: A force F = 4 5 , 0 0 0 N necessary to rotate the shaft at uniform speed is shown in Fig . 1

A force F=45,000N necessary to rotate the shaft at uniform speed is shown in Fig.1. The crank shaft is made of ductile steel whose elastic limit is 207MPa, both in tension and compression. With Elastic modulus E =207GPa, Poisson's ratio =0.25, determine the diameter of the shaft, using the maximum shear stress theory and distortion energy theory. Use a factor of safety N=2. Consider a point on the periphery at section A for analysis.
