Homework Equations
[/B]
So I can just sum up all the forces then sum the moments?
The Attempt at a Solution
[/B]
FBx = 0 lb
FCx = 800 cos30 = 692.82 lb
FEx = 0 lb
FBy = -2500 lb
FCy = 800sin30 = 400 lb
FEy = -1200 lb
Resultant force:
FAx = 0 + 692.82 + 0 = 692.82 lb
FAy = -2500 + 400 - 1200 = -3300 lb
Moments about point C:
MOB = (2500)(2) = 5000 lb*ft counterclockwise
MOC = 0 lb*ft
MOE = having trouble with this oneDoes everything seem ok here so far?
