Question $2$

$($a$)$ Determine the components of the $250N$ force $P$ acting vertically downward along the two struts $AB$ and $BC.$

$($Note: We ask specifically for components of a given force, and not to analyse a frame.$)$

$($b$)$ What do you have to specify in order that the components of $P$ are completely known?

$($c$)$ Determine the components of the $250N$ force along the strut $AB$ and parallel to the vertical wall.

$($d$)$ Determine the components of the $250N$ force parallel and perpendicular to the vertical wall.

$($e$)$ What do you perceive from your three sets of components?
