The member shown is supported by two bearings (simple supports) at O and D (note: take O as a pin support and D as a roller support). The dimensions are OC = 60 cm, CD = 40 cm, BC = 50 cm, AB = 30 cm, and the diameter is 2 cm. Two equal torques are acting near O and D, in addition to the forces at A and B as shown.
Tasks: a) Draw Free Body Diagrams in the x-y plane and x-z plane for the member OD.
b) Draw the axial force, torque, shear force, and bending moment diagrams for OCD in the x-y and x-z planes.
