The trailer hitch from Figure 1-1 (p. 11) has loads applied as shown in Figure 3. The tongue weight of 980 N acts downward and the pull force of4 905

N acts horizontally. Using the dimensions of the ball bracket in Figure1-5 (p. 14), draw a free-body diagram of the ball bracket and find the tensile and shear loads applied to the two bolts that attach the bracket to the channel in Figure 1 -1.
