Convert the system of forces to an equivalent single resultant force and a corresponding couple at C. Find the projection of the couple at C along a line adjoining DE. Sketch the system.

2. Equations related.

Fr = F[tex]_{1}[/tex] + F[tex]_{2}[/tex] + F[tex]_{3}[/tex]

M = r x F

3. Attempt at the problem.

Is this correct?

Fy = F[tex]_{3}[/tex] - F[tex]_{1}[/tex]

Fx = 0

Fz = F[tex]_{2}[/tex]

Then find Fr = [tex]\sqrt{Fy^{2} + Fx^{2} + Fz^{2}}[/tex]

M = r x F.

So does that mean I draw a perpendicular line from C to the line of D and E.
