Suppose a beam is loaded with three forces as shown in Figure $1.$

$0\mathrm{.}5($a$)$ Show all reaction forces on a sketch

$30\mathrm{.}5($b$)$ Calculate all reaction forces

$0\mathrm{.}5($c$)$ Determine magnitude of the resultant force at support B and its orientation about the horizontal direction using the analytical method

$0\mathrm{.}5($d$)$ Present the resultant force at support B and its components on a sketch
