Q3. A truss is shown in Figure Q3. The truss has two pin supports at points A and D. At points C and E, two vertical point loads with the intensity of 5 kN and 8 kN have been applied to the truss, respectively. Support D has settled down for 30 mm. The modulus of elasticity, E for all members is 200 GPa. The cross sectional area, A of all members is 500 mm². (c) (b) By taking the vertical reaction at D as redundant, determine its value. (d) Determine the degree of indeterminacy of the truss. 4 m Determine all support reactions. Determine axial forces of all members.
