# Statics -- Net Moment

## Homework Equations

I can see how the net force is not the same but I'm not getting the net moment.

## The Attempt at a Solution

12mm x 10N = 120N-mm. How do these two FBDs not have the same net moments.

Thanks for any help!

Welcome to the PF.

What is the actual problem statement? Something about showing the two situations do not have the same net forces and net moments?

How do these two FBDs not have the same net moments.

If I'm reading this right, it looks like the FBD on the right is just the FBD on the left, except it's showing you the moment caused by the 10N force. Or in other words, the 10N force is still there they're just not showing it and the net moment is the same on both. Of course I'm not sure what the actual problem statement is, so...
