Rigid body is defined as a system of particles in which distance between each pair of particles remains

constant (with respect to time).

Read moreA body is said to be in pure translational motion, if the displacement of each particle of the system is same

during any time interval.

Read moreAs a measure of the way in which the mass of rigid body is distributed with

respect to the axis of rotation, we define a new parameter, the radius of gyration

(K). It is related to the moment of inertia and total mass of the body.

Read moreA uniform disc of radius R has a round disc of radius R/3 cut as shown in Fig.

.The mass of the remaining (shaded) portion of the disc equals M. Find the

moment of inertia of such a disc relative to the axis passing through geometrical

centre of original disc and perpendicular to the plane

of the disc.

Read moreTorque represents the capability of a force to produce change

in the rotational motion of the body

Read moreThe torque of a force ?

F about an axis AB is defined as the component of torque of ?

F about any

point O on the axis AB, along the axis AB.

Read moreA couple does not exert a net force on an object even though it exerts a torque

Read morePoint of Application of force is the point at which, if net force is assumed to be acting,

then it will produce same translational as well as rotational effect, as was produced

earlier.

equilibrium

MOTION OF A RIGID BODY

Read moreFor a rigid body as earlier stated value of angular displacement (?) , angular velocity (? ),

angular acceleration (?) is same for all points on the rigid body about any other point on the

rigid body

Read morePure Rolling (or rolling without sliding)

Read moreThis motion can be viewed as translation of centre of mass and rotation about an axis

passing through centre of mass

Read moreIt is the axis about which the combined translational and rotational motion appears as

pure rotational motion

Read moreRolling on moving surface

Read moreIn many situations an external force is applied to a body to cause it to slide along a

surface. In certain cases, the body may tip over before sliding ensues. This is known

as topping.
