## Homework Statement

I have to solve for Ay, By, and Cy reaction forces. The constant C is a couple acting at A in a clockwise direction

## Homework Equations

Sum of all forces = 0

Sum of Moments about any point = 0

## The Attempt at a Solution

I solved for all four reaction equations(one force sum and three moment equations at a,b, and c) These are the four equations I calculated:

Ay + By + Cy = 0

36(By) + 3(36)(Cy) = C

2(36)(Cy) - 36(Ay) = C

-3(36)(Ay) -2(36)(By) = C

But no matter how I try to solve the system of equations I always get 0 = 0 or a singular matrix. I don't know if the problem is that I messed up with one of the moment equations or if there is something else I need to do. Any help would be very much appreciated, thanks!
