Problem #$3$:

The vector sum of the forces acting on the beam is zero, and the sum of the moments about the left end of the beam is zero.

$($a$)$ Determine the forces Ax and Ay$,$ and the couple MA$.$

$($b$)$ Determine the sum of the moments about the right end of the beam.

$($c$)$ If you represent the $600-N$ force, the $200-N$ force, and the $30N-m$ couple by a force $F$ acting at the left end of the beam and a couple M$,$ what are F and M$?$
