Balance System with Physics

I am trying to figure out how I would approach making a balance system. Much like a Justice Balance or a Weighing Scale (shown below) where there are two sides connected at a pivot point in the center. When objects are put onto one side the other side will go up, while the one with the objects will go down.

I am new to Unity and scripting so at the moment I am a little lost at what to do. If anyone could point me in a direction or any advice to give on how to achieve this I appreciate it. Thanks Guys!

You need to create separate gameobjects for each part that is supposed to be moving.

say you have one foundation
one lever
two platforms

then connect the foundation to the lever thru a hinge joint. connect the platforms to each end of the lever with hinge joints too.

if you want to drop stuff onto the platforms, you need a collider on the platforms so the things you put there will not fall thru the platform. the things you add should have a collider, a rigidbody with some mass and usegravity.
