How can general body be obtained ?
General body is considered as a system of particle instead of considering only a one particle. By considering a general body as a system whole mass of it concentrated on its centre of mass and all external forces acting on the centre of mass.
Such type of assumption leads to determine the motion of centre of mass of system.
Explain with illustration the pure translation and combination of translation and rotation motion of rigid body.
A uniform solid cylinder of mass $M$ and radius $R$ rotates about a frictionless horizontal axle. Two similar masses suspended with the help two ropes wrapped around the cylinder. If the angular velocity of the cylinder, after the masses fall down through distance $h$, will be
In rotational motion of a rigid body, all particle move with
What is the total momentum of the system of particle ?
Figure shows a small wheel fixed coaxially on a bigger one of double the radius. The system rotates about the common axis. The strings supporting $A$ and $B$ do not slip on the wheels. If $x$ and $y$ be the distances travelled by $A$ and $B$ in the same time interval, then
