dimensions are given in mm$,$ as well as a recommended co$-$ordinate system. A vertical force $P=300$

N acts on the end of the Hanger arm.

$($a$)$ Consider the portion of the structure between the external force and the section plane B$-$B$.$ Make

a neat sketch, showing the internal forces, moments or torques at the virtual face cut by $A-A,$

necessary to balance the external load.

$($b$)$ Repeat this but for the section plane A$-$A$.$Please solve asap answering every guestion clearly with axplanations
