# What is Centrifugal force?

Fri June 08, 2012

Centrifugal force represents the effects of inertia that arise in connection with rotation and which are experienced as an outward force away from the center of rotation. In Newtonian mechanics, the term centrifugal force is used to refer to one of two distinct concepts: an inertial force (also called a "fictitious" force) observed in a non-inertial reference frame, and a reaction force corresponding to a centripetal force.

The term is also sometimes used in Lagrangian mechanics to describe certain terms in the generalized force that depend on the choice of generalized coordinates.

The concept of centrifugal force is applied in rotating devices such as centrifuges, centrifugal pumps, centrifugal governors, centrifugal clutches, etc., as well as in centrifugal railways, planetary orbits, banked curves, etc. These devices and situations can be analyzed either in terms of the fictitious force in the rotating coordinate system of the motion relative to a center, or in terms of the centripetal and reactive centrifugal forces seen from a non-rotating frame of reference; these different forces are equal in magnitude, but centrifugal and reactive centrifugal forces are opposite in direction to the centripetal force

# This is the answer of question 15 in selina physics class 10 solutions which you have given. What is the reason of force being applied in this direction only? To lift up the wheel on the platform, Point X will become the point of rotation of the wheel. Why can't the force be applied at the diameter of the wheel so that the perpendicular distance of the line of action of force from the axis of rotation is maximum? This is one of the factors affecting torque. Torque is directly proportional to the perpendicular distance of the line of action of force from the axis of rotation. Therefore, by applying the force at the diameter, the perpendicular distance increases and due to this, the moment of force also increases. therefore, by applying minimum effort, the wheel can be raised.
