Problem $2$: Internal shear force$/$bending moment

$(20$ points$)$

For the frame structure shown below, point A is a roller, and point C is a pin support. With the loads shown in figure $2,$

$($a$)$ Find all the support reactions. $(5$ pts$)$

$($b$)$ Draw the shear and bending moment diagram for the frame. $(10$ pts $)$

$($c$)$ Draw the deflection shape $(5$ pts $).$
