Problem $4$: $(25$ points$)$

The loading diagram for a cantilevered beam is shown below. The support at $A$ is fixed.

$($a$)$ Determine the support reactions at $A.$

$($b$)$ Determine the shear and bending moment as a function of $x,$ where

$($i$)0$ ft $x6ft$

$($ii$)6ftx10ft$

Please draw the relevant FBDs$.$

$($c$)$ Draw the shear and bending r$.$

$($d$)$ Indicate the maximum absolute values of shear and bending moment. Why is it important to know these values?
