The document describes analyzing a four bar truss to determine its deformation, maximum stress, and reaction forces. The truss is made of elements that each have a modulus of elasticity of 29.5 GPa and cross-sectional area of 1 square meter. The results show a deformation of -22.25 mm, a stress of 4167 N/mm^2, and reactions forces of Fx = 4167 N and Fy = 3126 N. These results are then validated by comparing to results from ANSYS simulations.

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

58. Consider the four bar truss shown in fig. It is given that E = 29.5 X
105 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
