Concept explainers

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.

Question

1. A 2m long uniform seesaw AB is supported at its
geometric center. A 600N boy sits 15 cm from point
A. How far from point B should a 1700N man sit so
that the seesaw remains in a horizontal position?
2. A uniform pole 20ft long and weighing 80lb is
supported by a boy 2ft from the left end A. and a
man from 5ft from the right end B. at what point
should a load of 100lb be so that the man will
support twice as much as the boy?
