Problem 7: Two children of mass 17 kg and 32 kg sit balanced on a seesaw with the pivot point located at the center of the seesaw. -If the children are separated by a distance of 3.0 m, at what distance, in meters, from the pivot point is the smaller child sitting in order to maintain the balance? Problem 10: Two children push on opposite sides of a door during play. Both push horizontally and perpendicular to the surface of the door. One child pushes with a force of 19 N at a distance of 0.575 m from the hinges, and the second child pushes at a distance of 0.47 m. -What is the magnitude of the force, in newtons, the second child must exert to keep the door from moving? Assume friction is negligible.
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.
