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.
