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.
In order to lift a shovelful of dirt, a gardener pushes downward on the end of the shovel and pulls upward at distance l2 from the end, as shown below. The weight of the shovel is m g → and acts at the point of application of F →2. Calculate the magnitudes of the forces F →1 and F →2 as functions of l1, l2, mg, and the weight W of the load. Why do your answers not depend on the angle θ that the shovel makes with the horizontal?
