Use the finite element method to calculate nodal displacements, member stresses, and the support reactions in the bar shown in Fig.Q1.
Modulus of Elasticity = 200,000 MPa
A1 = 10 mm^2
A2 = 25 mm^2
A1 = 50 mm^2

The total load at node 3 is 500 N. This is a statically indeterminate problem and therefore it cannot be solved by simple "Strength of materials" theory.
