Torque Problem????

[pinky2468]

I have no idea how to do this! My teacher never really showed us how to determine clockwise and counterclockwise torque. Any help would be greatly appreciated!!

Referring to the diagram(I have attached it):
1. Which forces create counterclockwise torques and calculate the sum of these torques.
2. Which forces create clockwise torques and calculate the sum of these torques.

I forgot to add Xo=.4610m

This is probably very simple, but I don't have a clue!! Thanks!

Please help, I added the missing Xo. How do you know if it clockwise or counterclockwise?

This was almost exactly like a problem I had on my provincial exam last year.

Depending on where you put the....jesus...whatever the triangle thing is called...the forces to the left are counter clockwise torques and to the right are clockwise torques. Think of the force pulling the beam down and the beam rotating in a C or CC motion. That's how I always thought about it.
