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.
The diagram shows a uniform diving platform supported from below a strut. THe platform, whih has a mass of 75 kg, is held in a horizontal positions and is attached to the tower at the point P. The force exerted on the platform by the strut is directed along the strut. A diver with a mass of 100 kg is standing at the end of the platform preparing to dive.
a. WHat is the magnitude of the force that the strut exerts on the platform?
b. What are the horiztonal and vertical componetnts of the force at the point P?
