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.
Consider the person lifting a heavy box with his back, shown in Figure,The mass of the upper body is 55.0 kg and the mass of the box is 30.0 kg.
Calculate the magnitude of the force FB –in the back muscles that is needed to support the upper body plus the box and compare this with his weight.
