Three children is trying to balance a uniformed seesaw. Boy A who has a mass of 20-kg is placed 3.5 meters away from the support on the one side of the seesaw. Boy B who has a mass of 40-kg sits 2.5 meters away from the support on the opposite side of the seesaw. The seesaw is made up of a steel that is 10-kg and 10 meters long. Where should the girl whose mass is 25-kg place herself to balance the seesaw? Find the magnitude of the upward force exerted by the support on the steel.
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.
