A beam supports both a uniform distributed load and a concentrated force, as shown in the figure below. The uniform distributed load has a magnitude and extends from to to the right of point A$.$ The concentrated force has a magnitude $,$ is inclined by an angle $,$ and acts to the left of point B$.$ The beam has an overall length $,$ and is held in equilibrium by a pin at point A and a roller at point B$.$ Neglect the height and weight of the beam for this analysis. Determine the support reactions at points A and B$.$A beam supports both a uniform distributed load and a concentrated force, as shown in the figure below.

The uniform distributed load has a magnitude $q=30l\frac{b}{f}t$ and extends from $L_1=0ft$ to $L_2=6ft$ to

the right of point $A.$ The concentrated force has a magnitude $F=750lb,$ is inclined by an angle $=75,$

and acts $L_3=7ft$ to the left of point $B.$ The beam has an overall length $L=20ft,$ and is held in

equilibrium by a pin at point A and a roller at point $B.$ Neglect the height and weight of the beam for this

analysis. Determine the support reactions at points A and $B.$
