The tow hitch is held in place by a retaining pin that isdesigned to fail before the fasteners between the tow package andthe vehicle frame fail. The tow package is designed for 6,000lb asapplied to ball hitch. You are tasked with designing the shear pin(retaining pin) for the hitch and have been asked to considertowing the trailer through different gradients up to a maximum of15%. Determine the internal normal and internal shear on the tongueof the hitch (square tube behind the ball) for various gradientsbetween 0% and 15%. Plot these internal loads with respect toincreasing gradient.
