R$7-1.$ The beam $AB$ is pin supported at A and supported

$7$

by a cable $BC.$ A separate cable $CG$ is used to hold up the frame. If $AB$ weighs $120l\frac{b}{f}t$ and the column $FC$ has a weight of $180l\frac{b}{f}t,$ determine the resultant internal loadings acting on cross sections located at points $D$ and $E.$ Neglect the thickness of both the beam and column in the calculation.
