Question 1

On analysis of a steel truss due to certain loading, the internal forces are found as shown below. The cross-sectional area of all the members of the truss was 100mm

^{2}.If the cross sectional area of member BC was increased to 1000mm^{2}, find the internal force in member BC.

Question 2

Find the number of zero force members in the given truss, if an external load P is applied at B.

Question 3

The member forces in the member marked P, Q and R for the truss as shown below, are (respectively)

Question 4

A 2D truss, with the applied loads s shown below in the figure. If AE = 40 kN, where A is cross section area and E is modulus of elasticity, then the strain energy (in kN-m) in the member XY is

Question 5

Determine the horizontal displacement (in mm) at B due to a variation of temperature from 20

^{o}C to 40^{o}C. ( Take α = 10 x 10^{-6}/^{o}C )Question 6

A simply supported truss shown in the given figure carries a load as shown. The force in member BE is?
