Which type of forces are responsible in explosion of chemical bomb internal or external forces ?
Explain with illustration the pure translation and combination of translation and rotation motion of rigid body.
Which forces needed for the rotational motion about a fixed axis ?
In the following figure, a body of mass $m$ is tied at one end of a light string and this string is wrapped around the solid cylinder of mass $M$ and radius $R$. At the moment $t = 0$ the system starts moving. If the friction is negligible, angular velocity at time $t$ would be
Explain translational motion by given illustration.
How to be verify fixed axis ?
