Use matrix methods in MathCAD to solve the frame below. Members $1$ and $2$ are

$8\mathrm{.}85i{n}^2$ and $\{$:$I=291i{n}^4).$ Member $3$ is a W$16$x$26$ and $\{$:$I=301i{n}^4).$ The modulus of

elasticity, $E=29000$ksi. Report the reactions, the lateral displacement at each end of member $3,$ and

the member end forces. Provide both your MathCAD $.$mcdx file and the worksheets printed to pdf$.$

The frame from problem $1$ is modified slightly $-$ a moment release is to be applied at the right end of

member $3.$ Solve the frame again in MathCAD, Report the reactions, the lateral displacements at

each end of member $3,$ and the member end forces. Provide both your MathCAD $.$mcdx file and the

worksheets printed to pdf$.$ Provide a brief comparison of the results between the $2$ frames.
