The bridge below has been designed to hold the distributed loads shown. The bridge roadbed behaves

like a beam that is attached to a truss by supports that extend downward from the road bed to pins B

and $C,$ shown by dashed lines below; those supports only transfer force between the beam and the truss

in the $y-$direction. Determine the internal forces in members $AB,EF,EC,$ and $BC$ as w

ell as the internal

force at point $G.$

Please solve for Ab$,$ EF$,$ EC$,$ BC and G
