Time : 3 hours    Full Marks : 70

Use separate answerscript for each half.

Answer SIX questions, taking THREE from each half.

The questions are of equal value.

Two marks are reserved for neatness in each half.

FIRST HALF

1. Figure Q1 shows the plan of a space truss. The ends B, C and D are simply supported in same horizontal plane. A load of lOOkN is acting vertically downward at A. Find the forces in all members. The co-ordinates of joints are shown in bracket.

2. A plane truss is shown in figure Q2. Find the vertical deflection at joint where the load of 30kN is acting. Assume modulus of elasticity as 200GPa and cross section area as 300mm² for all members.
