How Is Torque Calculated in This Physics Problem?

Homework Statement

Please see the attached picture. But I'm trying to do is figure out where this moment would be created and how much torque would be applied based upon this example.

Homework Equations

T = fxd

I would suspect that any weight added to the left side of the axle would be pushing the system in a counterclockwise fashion. And, conversely, I need weight added on the right side of the axle wood have a tendency to counter that by pushing the axle in a clockwise fashion. I believe the total torque to be:
980 Nm

If your diagram is accurate, yes, but it looks odd that in spite of the lever arm being rotated to some unspecified angle to the horizontal the weight is exactly 1m horizontally from the axle. Maybe you shoukd post the original question exactly as given to you.

Your question about where exactly the torque is applied suggests some misunderstanding. The torque applies at whichever point you chose to calculate it about; in this case, the centre of the axle.
