Question $2.$

The frame shown in Figure Q$2$ has pinned supports at A and $F.$ Joint $E$ is internal hinge.

$($a$)$ Determine the reactions at the supports A and $F.$

$($b$)$ Draw the annotated axial force diagram for the frame.

$[$Use a negative sign to indicate a compressive force$]$

$($c$)$ Draw the annotated shear force diagram for the frame.

$($d$)$ Draw the annotated bending moment diagram for the frame.
