1. Governor apparatus.

A governor is a device used to measure and regulate the speed of an engine. To minimize fluctuations in the mean speed which may occur due to load variation, the governor is used. When there is a change in load, variation in speed also takes place then-governor operates a regulatory control and adjusts the fuel supply to maintain the mean speed nearly constant. Therefore, the governor automatically regulates through linkages, the energy supply to the engine as demanded by variation of the load so that the engine speed is maintained nearly constant. The broad classification of the governor can be made depending on their operation. There are basically two types of governors. Centrifugal governor, inertia governor. In centrifugal governors, the centrifugal force is balanced by the controlling force. These types of governors are used extensively. In the inertia type of governors, the inertia force is balanced by the controlling force. The centrifugal governors can be further classified as follows (1) Pendulum type e.g. Watt governor. (2) Loaded type e.g. Porter governor, Proell governor, Hartnell governor, Hartung governor.

 

 

 

2. Gyroscope Apparatus

A gyroscope is a device used for measuring or maintaining orientation and angular velocity It is a spinning wheel or disc in which the axis of rotation (spin axis) is free to assume any orientation by itself. When rotating, the orientation of this axis is unaffected by tilting or rotation of the mounting, according to the conservation of angular momentum. A gyroscope is an instrument, consisting of a wheel mounted into two or three gimbals providing pivoted supports, for allowing the wheel to rotate about a single axis. A set of three gimbals, one mounted on the other with orthogonal pivot axes, may be used to allow a wheel mounted on the innermost gimbal to have an orientation remaining independent of the orientation, in space, of its support. All spinning objects have gyroscopic properties. The main properties that an object can experience in any gyroscopic motion are rigidity in space and precession.
