QUESTION $2(60\%)$

The following system, shown in Figure $2,$ is modeled using $5$ finite elements; the element numbers are shown. Elements $1$ and $2$ are modeled using beam elements, elements $3$ and $4$ are truss elements, element $5$ is a linear spring. The parameters of each element are given in Table $1.$ Using the finite element method, determine:

a$)$ the displacements of each node? $(10\%)$

b$)$ the strain of each truss element? $(10\%)$

c$)$ the stress of each truss element? $(10\%)$

d$)$ the loads within each truss element? $(10\%)$

e$)$ verify the results from part a$,$ b$,$ c and d using ANSYS? $(20\%)$
