The required steps, process, diagrams, and$/$or unknowns are specified below.

The plane rigid frame is carrying loads as shown in Fig. $2.$ The nodal numbers are indicated in Fig. $2.$ It's required that a two$-$element model must be used for the analysis. Note that the support Lat wode $2$ experiences a displacement of $1\mathrm{.}5$ in $.($horizontal$,$ towards the left$).$ By means of the structural finite element method:

$($a$)$ Compute the equivalent nodal loads.

$(15$ points$)$

$($b$)$ Draw a diagram of the frame carrying the equivalent loads $($magnitudes and directions must be clearly indicated on the diagram$).$

$(4$ points$)$

$($c$)$ Determine the nodal displacements at node $1.$

$(14$ points$)$

Take $A_1=10i{n}^2,A_2=15i{n}^2,I_1=100i{n}^4$ and $I_2=200i{n}^4.$ Use $E=400$ksi for entire frame.
