A cantilever beam is loaded by a distributed load as shown in the following figure.

$($a$)$ Draw the FBD for the entire beam AB$.$

$($b$)$ Determine the end reactions at support $A.$

$($c$)$ Working on section AC$,$ determine the internal loads $($shear force and moment$)$ at C$.$

$($d$)$ Comparing your solution of part $($c$)$ and the solution that we have worked out from section CB$,$ what conclusion$($s$)$ can you draw?
