A rigid bar is an lever that can do pulling,pushing,lifting and raising an object :)
In classical physics, a rigid body is an idealization where the distance between any two points on the body remains constant. However, in reality, all physical bodies have some degree of flexibility or deformation under certain conditions. Therefore, there is no truly rigid body in practice.
A cell wall, usually found in plant cells, is rigid.
Collenchymatous cells have rigid cell wall
The cell wall is a rigid supporting structure.
The rigid shell or case of protozoans and rotifers is called a lorica. It provides protection and support for these microorganisms.
The rigid bar is not called a fulcrum! And, by the same token, why is the bar called a bar?

it's was a lever ..........

I don't know that's why I'm asking
A lever.
I'm guessing a lever, but someone please re-answer this if I'm wrong.
The scenario described is a simple pendulum. The rigid bar A, also known as the pendulum arm, swings from a fixed point called the pivot point or fulcrum. The motion of the pendulum is influenced by factors such as its length and the force of gravity acting upon it.
A lever is a simple machine consisting of a rigid bar that pivots around a fixed point called a fulcrum. It is used to amplify force or create motion by applying pressure at one end of the bar. Levers are commonly used in various tools and equipment to make tasks easier.
