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.
1a)
A light, inextensible cord passes over alight,
frictionless pulley with aradius of 9:5cm.
It has a(n) 19 kg mass on theleft and a(n)
7:7 kg mass on the right, bothhanging freely.
Initially their center of massesare a vertical
distance 2:4 m apart.
The acceleration of gravity is9:8m=s2 :
At what rate are the two massesaccelerat-
ing when they pass each other?Answer in
units of m=s2.
b)
What is the tension in the cordwhen they
pass each other? Answer in unitsof N.
