Homework Statement
Determine the moment about point B of each of the three forces acting on the beam.
Homework Equations
M = F*d⊥
The Attempt at a Solution
I went and found the components for each of the forces. Please double check it if I did them right:
F1 :
Fx = 0
Fy = 375 lb
F2:
Fx = -500(3/5)lb = -300lb
Fy = -500(4/5)lb = -400lb
F3:
Fx = 160cos30° = 138.6lb
Fy = -160sin30° = -80lb
If those components are right, I'm having trouble finding their perpendicular distances.
