The document provides information about determining nodal displacements and stresses in members of a two bar truss shown in a figure. It gives the modulus of elasticity, member area, nodal displacements, and calculates the theoretical stress in a member based on the given displacements and modulus to compare to the finite element method result.

1. Two bar truss shown in fig. Determine the nodal displacements and the stress
in each member.
Take E = 210 X 109 Pa, Area A= 0.01m2

2. q1 = q2 = q5 = q6 = 0
q3 = 0.048 X 10-3 m
q4 = -0.182 X 10-3 m
σ = E ε = 210 X 109 X 0.048 X 10-3
=10.08 X 106 N/m2
