A person places a bathroom scale in the center of the floor and stands on the scale with his arms at his sides. If he keeps his arms rigid and quickly moves them up and over his head, he notices the scale reading increase as he brings his arms upward? Why? Then , with his arms over his head, he quickly lowers his arms to his side, How does the scale reading change and why?
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.
