Problem $1$c$.1$

The inclined beam has a mass of $120$ kg and center of gravity at $G.$ The beam is supported by a roller at $A,$ cable $AB,$ and a smooth peg in a slot at $C.$ The $1500$ N force is perpendicular to the beam.

Calculate the reaction forces at these supports.

Answers: $N_C=2871N$;$N_A=193\mathrm{.}9N$;$T=709\mathrm{.}7N$
