Problem $7$: The below system is similar to a common panelized roof system $($represented in $2$D$).$ members CD$,$ DE$,$ EF$,$ FG sit on purlins which collect load from into and out of the page. They transfer the load as shown to member AB $.$ Draw the shear and bending moment diagrams for beam CD$,$ DE$,$ EF$,$ FG and AB$.$ Hint: Start by drawing FBD of each member individually.
