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)
