Problem $12\mathrm{.}42-$ Enhanced $-$ with Hints and Feedback

Consider the frame shown in $($Figure $1).$ Suppose that $P_1=4k$ and $P_2=8k$ Each column has the cross$-$sectional area indicated. Solve the problem using the cantilever method of analysis. Assume that the internal moment, shear, and normal force in the vertical beam are positive if they act as shown in $($Figure $2)$
