QUESTION 1 Figure Q1 below shows a steel truss pinned at both support A and E. This truss system subjected to 10 kN/m horizontal uniformly distributed load along the member of CE and the vertical load of 20 kN at joint B and D. (CO1-PO1) a) Find the determinacy of the truss. (CO1:PO1) (C2) (3 marks) b) Determine the vertical displacement at joint B by using Unit Load Method. All member have cross sectional area of 250mm² and same modulus of elasticity 200 GPa. (CO1:PO1) (C4) (15 marks) IZZA A k 10kN/m 5m 20kN Vil B C 5m 20KN 4m 4m
