Calculating Torque and Lever Arm

[frownifdown]

Here is the problem http://imgur.com/6KRKJQu
Torque = force x lever arm
We are told that the force is all the same so the only thing that would determine the torque is the size of the lever arm. The ones that I'm not sure about are B and C. The rest I think I have done correctly. Just to make sure I'm doing it right though, I drew the line of the force straight down from D and drew a line from axis to this perpendicular and it measured to be 6. That's the correct method, correct?

hi frownifdown!

correct

(do you mean B and F ?)

show us what you got for those
