Problem $4$:

The simply supported beam ABCD is loaded by a weight $W=30kN$ through the

arrangement shown in the figure.

The cable passes over a small

frictionless pulley at $B$ and is

attached at $E$ to the end of the

vertical arm.

Plot the internal reaction

diagrams for the rod ABCDE $.$

$($Note: Disregard the widths of the

beam and vertical arm and use

centerline dimensions when

making calculations.$)$
