Create a simple balance using a ruler as the balance beam and a pencil as the fulcrum. Put 2 nickels stacked together on one side of the ruler and a single nickel on the other side so that the ruler is balanced. Does the distance from the fulcrum to the 2 nickels = 1/2 the distance to the single nickel? How would you account

Rotational Equilibrium And Rotational Dynamics

In physics, the state of balance between the forces and the dynamics of motion is called the equilibrium state. The balance between various forces acting on a system in a rotational motion is called rotational equilibrium or rotational dynamics. 

Equilibrium of Forces

The tension created on one body during push or pull is known as force.
