Fly-wheel is used with an engine because it
Increases the efficiency of engine
Converts linear motion into rotatory motion
Is compulsory by law
Makes the motion smooth and cuts down the vibrations
In the given figure linear acceleration of solid cylinder of mass $m_2$ is $a_2$. Then angular acceleration $\alpha_2$ is (given that there is no slipping).
What is precession ?
What is combined translation and rotation motion ?
$A$ uniform cylinder of mass $m$ can rotate freely about its own axis which is horizontal.$A$ particle of mass mo hangs from the end of a light string wound round the cylinder which does not slip over it. When the system is allowed to move, the acceleration of the descending mass will be
In rotational motion of a rigid body, all particle move with
