5 bolts are made of low carbon steel with a yield point in shear of 19,200 psi. The bolts are 3/8 inch in diameter and are going to be used in a flanged coupling that transmits 285 hp @ 1250 rpm. If the bolts are to have a factor of safety in shear of 1.5, FIND the distance, r, from the center of the coupling at which the bolts should be placed. Is this distance the minimum or maxium?
