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