1. A steel hanger is bolted to a steel frame using two 5/8 in-18 UNF grade 7 bolts. The thickness of the hanger at the bolt is identical to that of the frame, 1 inch each. A vertical load varying between 0 and 40,000 lb is applied at the hanger. The bolts are initially tightened to 75% of its full proof load. The length of the bolt is two threads beyond the nut. Determine the factors of safety against yielding, overloading and joint separation, respectively. Also, estimate the torque required to develop the preload. F 1.
