When a body rotates, it experiences a force towards the center of the object. This force is called centrifugal force. This force tends to push the rotating object out of the circle. The magnitude of the centrifugal force is directly proportional to the mass as well as the velocity of the object, while the force is inversely proportional to the circle in which the object is rotating. Using this apparatus, the characteristics of centrifugal force can be studied. This unit consist of a small metallic rod which is placed on a guided path with the help of two grooves. The rod has a vertical axis of rotation. Some mass can be placed on the rod as the rod contains some retaining holes. During rotation, the centrifugal forces exerted on the metal rod are transmitted to a bending bar. The deformation of the bending bar is directly proportional to the centrifugal force. The force is recorded by an electronic measuring system and is displayed digitally. In simple terms, the centrifugal force that acts on the rod, from the attached mass, during rotation is displayed on the force indicator on the control panel. The rotational speed of the rod is adjusted using a control panel. Similarly, the rotational speed of the drive motor can also be adjusted through the 10-turn potentiometer. This speed is also displayed digitally on the control panel. This unit is covered with a transparent lid for protection from rotating parts while providing clear view of the operation of the device. This unit is portable and can be set up wherever the user requires. It does not need to be clamped in place.
