Problem $2$

For the frame shown, determine the reactions at the

supports $($support A is a hinged while B is a roller$).$

$($a$)$ Determine the resultant reaction at the

hinged support.

$($b$)$ Determine the reaction at the roller support.

$($c$)$ Determine the shear at $2\mathrm{.}5$ meters from

point $D$ along the beam.

$($d$)$ Determine the moment at $4$ meters from

point A along the beam.
