Homework Equations
Right Hand Rule
The Attempt at a Solution
I have to find the moments at B. I know I have to use the right hand rule to figure out which force has a positive and which force has a negative action. However, I'm not too certain on how to do this. I know how to position my right hand, but I don't know whether to use the "up thumb" or "down thumb" for a specific point.
Please Help.
