The beam ABCD shown in Figure $3$ has a fixed support at Point $A,$ a hinge at Point $B$ and a roller support at Point C:

$($a$)$ On a sketch of the structure, show the possible reaction components at the supports.

$($b$)$ Show that the system is statically determinate.

$($c$)$ Using the equations of equilibrium, solve for the reaction components.

$($d$)$ Draw the Axial Force, Shear Force and Bending Moment Diagrams. Show the locations and magnitudes of maximum and minimum values.
