1. A bolt is expected to break at 105 ft-lb of torque. A cheater bar is being used to tighten the bolt. The cheater bar is placed on the wrench 3 inches from the center of the bolt. The cheater bar is made of pipe that is 6.6 pounds per linear foot. The bar is 5.7 feet long. What is the lowest angle above the horizon that that the bar can be held before it exceeds the maximum expected torque?
