Description of physical system help

[Edemardil]

This is not homework related and I am having some trouble with describing a part of a system. It is a Rube Goldberg machine. I have two vertical "levers" with axles in the middle of them. I'll post photos. I am really having trouble describing them more or less because I don't know what a good description of the objects them selves are. Are they levers? Latches? Hinges? Pendulums? This is keeping me from really describing them quantitatively because I am having trouble finding the right formulas for transferring energy, velocity, force all that, through that part.

Could someone help me or vaguely lead me to a direction to look for both items?

It is the yellow vertical poles that I am talking about.

From their action/usage, 'lever' would be the correct term.

Reasoning:
They have a point about which they pivot, an applied force and distance, and a resultant force and distance.
