A Pickering governor is mostly used for driving gramophone. It consists of three straight leaf springs arranged at equal angular intervals round the spindle. Each spring carries a weight at the centre. The weights move outwards and the springs bend as they rotate about the spindle axis with increasing speed.

Which one of the following governors is used to drive a gramophone?a)W...
Introduction:
A governor is a device used to control the speed of an engine or machine by regulating the amount of fuel or steam supplied to it. In the case of a gramophone, a governor is used to regulate the speed of the turntable, ensuring that the record plays at the correct speed.
Pickering Governor:
The correct answer to the question is option 'C', the Pickering governor. The Pickering governor is a type of centrifugal governor that is commonly used in gramophones.
Working Principle:
The Pickering governor consists of two rotating balls or weights that are mounted on a spindle. As the gramophone's turntable rotates, the balls are thrown outward by centrifugal force. This movement is transmitted to the control mechanism, which adjusts the speed of the turntable accordingly.
Advantages of Pickering Governor:
- The Pickering governor is compact and lightweight, making it suitable for use in small devices like gramophones.
- It is relatively simple in design and easy to maintain.
- The governor responds quickly to changes in speed, ensuring accurate speed control for the gramophone.
Comparison with other Governors:
- Watt Governor: The Watt governor is a centrifugal governor that was commonly used in steam engines. It is not suitable for driving a gramophone because it is larger and more complex than the Pickering governor.
- Porter Governor: The Porter governor is another type of centrifugal governor that was used in steam engines. Like the Watt governor, it is not suitable for driving a gramophone due to its size and complexity.
- Hartnell Governor: The Hartnell governor is a hydraulic governor that is used in certain types of engines. It is not commonly used in gramophones.
Conclusion:
In conclusion, the correct governor used to drive a gramophone is the Pickering governor. This compact and lightweight centrifugal governor is specifically designed for small devices like gramophones, providing accurate speed control for the turntable. Other governors like the Watt governor, Porter governor, and Hartnell governor are not suitable for this purpose due to their size and complexity.
