## Question:

Draw the free-body diagram of the beam supported at $A$ by a fixed support and at $B$ by a roller. Explain the significance of each force on the diagram.

Given:

$w$ = $40$ $\frac { Ib }{ ft }$

$a$ = $3$ $ft$

$b$ = $4$ $ft$

$\theta$ = $30$ $deg$

## Step-by-step

${ A }_{ x },{ A }_{ y },{ M }_{ A }$ effect of wall on beam.

${ N }_{ B }$ force of roller on beam.

$\frac { wa }{ 2 }$ resultant force of distributed load on beam.
