A Pickering governor consists of a spindle and three straight leaf springs (each consisting of a single leaf). These three identical leaf springs are symmetrically placed (i.e. at equal angular intervals) around the spindle.
What is Hartnell Governor? Working, Diagram & Construction
In Hartnell governor, movement of fly-balls is controlled by means of a spring. Therefore, Hartnell governor is also known as spring-loaded governor.
Construction of Hartnell Governor
Hartnell governor consists of a casing, in which, a pre-compressed spring of helical compression type is fitted so as to apply force on the sleeve.
What is Proell Governor? Working, Diagram, Construction & Applications
Proell governor is similar to Porter governor having central load at the sleeve. But, Proell governor differs from Porter Pivot governor in ‘size’ as well as ‘arrangement’ of fly-balls. Refer to Fig. 1.
Construction of Proell Governor
Difference Between Brake and Dynamometer
In this topic you study, the between brake and dynamometer.
What is Double Block (Shoe) Brake? Working, Diagram, Construction & Applications
When a single block brake is applied to a rotating drum for braking action, an additional load is produced on shaft bearings due to normal reaction (RN). This leads to unbalanced situation. In such cases, this unbalanced load acting on the shaft may lead to bending of shaft. Hence, to overcome this drawback of single block brake, double block (shoe brake) is used. Refer Fig. 1.

Difference Between Drum Brake and Disc Brake
In this topic you study, the difference between drum brake and disc brake.
What is Drum Brake? Working, Diagram, Construction & Applications
Drum brakes are widely used in different applications. They are the cheapest as compared to other types of brakes. Drum brake consists of a rotating brake drum mounted on the wheel and two semi-circular brake shoes attached on a stationary back plate. Pressing of brake shoes against the circumference or periphery of rotating drum causes friction resulting in braking.
What is Centrifugal Clutch? Working, Diagram, Construction & Applications
Centrifugal clutch is a type of friction clutches, which uses the property of friction existing between two contacting surfaces, like single plate and multi-plate clutches. But, the construction and working of centrifugal clutch eliminate the need of circumferentially or radially mounted clutch springs.
What is Multi Plate Clutch (Multiple Disc Clutch)? Working, Diagram, Construction & Applications
Multi-plate clutch is an extension of single plate clutch and works on the same principle as that of single plate clutch. Multi-plate clutch has multiple numbers of frictional and metal plates. This arrangement of multiple frictional and metal plates provides increased friction surface area, due to which, torque transmitting capacity of clutch increases. Therefore, multi-plate clutch is widely used in many applications.
What is Single Plate Clutch? Working, Diagram, Construction & Applications
Single plate clutch is the most commonly used type of clutch in automobiles. It provides quicker disengagement.
Construction of Single Plate Clutch
Single plate clutch consists of clutch disc, pressure plate, and a cover assembly, which are bolted to the engine flywheel (Fig. 1).
