PhysicsWork Done by a Torque or Couple Torque is an appraise of the force that can reason an object to rotate about an axis. It is a vector quantity. The path of…
PhysicsDefine Torque and Moment of the Torque or Couple There are many examples in practice where two forces, acting together, exert a moment. or turning effect on some object. As a very simple case,…
PhysicsExplain Moment of Force A force can rotate a nut when applied by a wrench or it can open a door while the door rotates on its hinges; in…
PhysicsTheorems of Moment of Inertia Theorems of Moment of Inertia: (i) Parallel axes theorem: The moment of inertia of a body about any axis is equal to the sum of…
PhysicsMoment of Inertia and its Physical Significance Moment of inertia is a determination of how complicated it is to rotate an exacting body about a given axis. It is a measure of…
PhysicsEquations of Rotational Motion As in linear motion, for a body having uniform angular acceleration, here derive the equations of motion. Let consider a particle start rotating with angular…
PhysicsWhat is Rotational Motion? When a body rotates about a fixed axis, its motion is known as rotatory motion. A rigid body is said to have pure rotational motion,…
PhysicsDefine Rigid Body in terms of Rotational Motion A rigid body is defined as that body which does not undergo any change in shape or volume when external forces are applied on it.…
PhysicsTypes of Equilibrium of Bodies There are three types of equilibrium of bodies. They are: (a) Stable equilibrium (b) Unstable equilibrium (c) Neutral equilibrium Consider three uniform bars shown in…
