Problem 2 The beam ABCD shown in the figure is simply supported at A and D, and has a circular cross- section with a diameter of 80 mm. The distributed force

acts at an angle of 60° to the Z axis and has components only along the Z and X axis. The 1.2 kN force acts parallel to the Z axis and the 1.5 kN force acts parallel the X axis. AB = 0.6 m, BC = 0.4 m and CD = 1 m. (a) Draw shear force and bending moment diagrams for the XY and YZ planes. 1.2 KN 60° 1.5 kN 4 kN/m DAD A₂ (b) Determine the maximum tensile and compressive bending stress in the beam and show their locations on the cross-section of the beam.
