## 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:

**F**

_{1}:F

_{x}= 0

F

_{y}= 375 lb

F

F

_{2}:F

_{x}= -500(3/5)lb = -300lb

F

_{y}= -500(4/5)lb = -400lb

**F**

_{3}:F

_{x}= 160cos30° = 138.6lb

F

_{y}= -160sin30° = -80lb

If those components are right, I'm having trouble finding their perpendicular distances.
