2. A horizontal beam supported by a vertical tension link. Determine the minimum width of a rectangular cross section for member C-D (the height must be 3 times of width), so that the maximum normal stress in member C-D does not exceed 500 MPa. The dashed line in the cross section indicates the axis along which the bending occurs. (15' in total) |H = 3W C Pin diameter = Rectangular cross section A 8.00 mm at A and C 1.5 m -2.5 m- B D 12.5 kN 3
