The moments around the pivot point need to sum to zero.

A moment is the centre of mass x distance from pivot.

So 1kg x 1m clockwise - 0.5kg x 2m anticlockwise = 0 and would be static.

The sign you give to each direction is arbitrary but you must be consistent.

Where this will get tricky if you want to be super accurate is friction at the pivot(ignore it) and the COG of your various masses but you should be able to get into the ballpark fairly easily.
