Figure P3–69 Shows a horizontal beam supported by a vertical tension link. The cross sections of both the beam and the link are 20 mm square. All connections use 8.00 mm-diameter cylindrical pins in double shear. Compute the tensile stress in member A-B, the stress due to bending in C-D, and the shearing stress in the pins A and C.
