How do I add wieght to one end of an object

I have an object sort of like a seesaw ( but not a seesaw) more like a capital "T"

I have a small sprite on one end pinned to the object.

How do I add a little weight to the small sprite so that if it isn't balanced just right, it will fall over?

Have you tested it out with the physics engine??

yea, but I can't seem to get it to do anything. it doesn't "tilt" over when I have the heavy sprite on one end of it.

Can you show your setup for everything? bBut both sprite and part have physics??

EDIT::

If you have physics on the sprite and the balance part it should function somewhere like this
