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:

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

$a$ = $3$ $ft$

$b$ = $4$ $ft$

$\theta$ = $30$ $deg$

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

Given:

[latex]w[/latex] = [latex]40[/latex] [latex]\frac { Ib }{ ft }[/latex]

[latex]a[/latex] = [latex]3[/latex] [latex]ft[/latex]

[latex]b[/latex] = [latex]4[/latex] [latex]ft [/latex]

[latex] heta[/latex] = [latex]30[/latex] [latex]deg[/latex]

Accepted Answer

[latex]{ A }_{ x },{ A }_{ y },{ M }_{ A }[/latex] effect of wall on beam.

[latex]{ N }_{ B }[/latex] force of roller on beam.

[latex]\frac { wa }{ 2 }[/latex] resultant force of distributed load on beam.
