A board of mass 3.0Kg serves as a seesaw for two children. Child A has a mass of 40Kg and sits 2.5m from the pivot point. At what distance x should a child B of mass 25Kg sit from the pivot point so as to balance the seesaw? What is the normal force at the pivot point? Assume the board is uniform and centered over the pivot
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.
