Centrifugal force is the apparent force that acts away from the center of a circular path. The force is always perpendicular to the direction of movement. The formula for centrifugal force is the same as for centripetal force: F c = mv 2 /r. However, centrifugal force acts in an equal and opposite direction. The force pushes or pulls an …

Centrifugal Force on Wind Turbine. The velocity of each particle inside the blade changes direction as the rotor rotates. This change of direction is a form of acceleration of the particle toward the center, or axis, that the blade revolves around. This acceleration is caused by the centripetal force.

The centrifugal force equation, expressed as F c = (m × v 2) ÷ r, calculates the outward force experienced by an object moving in a curved path. This force, denoted by F c, represents the apparent push away from the center that arises in a non-inertial reference frame. The variables m, v, and r represent the mass of the object, its velocity ...
