## Homework Equations

[/B]

So I can just sum up all the forces then sum the moments?

## The Attempt at a Solution

[/B]

F

_{Bx }= 0 lb

F

_{Cx}= 800 cos30 = 692.82 lb

F

_{Ex}= 0 lb

F

_{By}= -2500 lb

F

_{Cy}= 800sin30 = 400 lb

F

_{Ey}= -1200 lb

Resultant force:

F

_{Ax}= 0 + 692.82 + 0 = 692.82 lb

F

_{Ay}= -2500 + 400 - 1200 = -3300 lb

Moments about point C:

M

_{OB}= (2500)(2) = 5000 lb*ft counterclockwise

M

_{OC}= 0 lb*ft

M

_{OE}= having trouble with this one

Does everything seem ok here so far?
