Page 2 of 3 Q1 (a) Determine the support reactions for the beam shown in Fig.Q1 (a) and hence draw the shear force and bending moment diagrams for the beam noting all significant values. Ignore point of contraflexture. (b) If the beam cross section is as shown in Fig.Q1 (b) determine the maximum tensile and compressive bending stresses in the beam. Q2 (a) Determine the force in each of the members of the pin jointed framework shown in Fig. Q2 using the method of joints. Indicate the forces on a neat sketch of the framework and show whether they are tensile or compressive. (b) If the above truss has an additional gravity load of 5kN at node C evaluate the forces in members 2, 3 and 4 using the method of sections Fig.Q1 (a) A B 6m 5m w = 20kN/m C W1 = 5kN 15kN 4m D W2 = 15kN 150mm  10mm 10mm  300mm 300mm  20mm Fig.Q1 (b) 1 2 3 4 5 A B C D Fig.Q2 10kN 2m 3m 1m 2m 2m 5kN
