The pin is used to connect the three links together. Due to wear, the load is distributed over the lop and bottom of the pin as shown on the free-body diagram If the diameter of the pin is 0.40 in., determine the maximum bending stress on the cross-sectional area at the center section a-a. For the solution it is first necessary to determine the load intensities w1 and w2.
