Modeling and Analysis Lab Problem-5 solution: Static analysis of four bar truss element using ANSYS

1. Consider the four bar truss shown in fig. It is given that E = 29.5 X 106 N/m2
and area A = 1 m2 for all the elements. Determine the deformation, maximum
stress and the reaction forces in the truss system.
Results:
Deformation = -22.25 X 10-3 m
Stress = 4167 N/m2
Reaction = Fx = 4167 N
Fy = 3126N
