What Is Rigid Body The rigid body motion can be expressed as When a constraint is expressed by equalities it is termed as holonomic constraint and those who do not are called non holonomic constraints Again if the constraint is independent of time it is called scleronomic constraints and if it is dependent of time explicitly then it is called rheonomic
Rigid body is a body that does not get deformed or change its shape even due to the action of any external forces or loads In case of Rigid body the distance remains constant between any of the two points when the rigid body is under the action of loads A planar rigid body has 3 DOF degrees of freedom in the absence of any constraints while a spatial rigid body has 6 DOF three translations and three rotations The amount of DOF that is available for the bodies to move freely is therefore decreased by the amount of DOF that the joint permits when a joint is added between two rigid bodies

A rigid body rotates about a fixed axis with a variable angular speed in rad sec at any time t in seconds angular speed 3 5t rad sec To find The angle through which it rotates before coming to rest Formula required The Formula for instantaneous angular velocity d d t A system of two bodies of masses m and M being interconnected by a spring of stiffness k in its natural length moves towards a rigid wall on a smooth horizontal surface as shown in figure with a K E of system E
a Two equal and opposite forces acting on a rigid body such that their lines of action don t coincide constitute a couple This couple produces the turning effect on the body Hence the rigid body will rotate b If the two equal and opposite forces act in such a way that their lines of action coincide then the body will not rotate A rigid body has translational as well as rotational motion If a force couple is applied on the object then which of the following quantities remains unchanged due to the force couple 1 Rotational kinetic energy 2 Translation kinetic energy 3 Total kinetic energy 4 Angular momentum about centre of mass
