The figure shows a flat hanger bar for supporting shop equipment in a factory. The bar is fixed to a support by means of a bolted connection. The main part of the hanging bar is 1.5 inches wide. This width varies up to 3.0 inches. A 1.0-inch diameter bolt transfers the hanger bar load to the two top bracket plates. Determine the allowable stress of the tension load P in the hanger in the following two instances: to. The allowable tensile stress in the main part of the hanger is 16,000 psi. b. The allowable stress load between the hanger bar and the bolt is 26,000 lb/pu.
