A relay is an electrically operated switch that controls the flow of electricity in a circuit.

• Relays are used to control high power circuits with low power signals.

• They consist of a coil and one or more sets of contacts.

• Relays can be used for various applications such as controlling motors, lights, and appliances.

• Common types of relays include electromagnetic relays, solid-state relays, and reed relays.

A 4 stroke engine works by completing four distinct processes: intake, compression, combustion, and exhaust.

• Intake stroke: Fuel and air are drawn into the cylinder.

• Compression stroke: The piston compresses the fuel and air mixture.

• Combustion stroke: The spark plug ignites the mixture, causing an explosion that pushes the piston down.

• Exhaust stroke: The piston pushes the exhaust gases out of the cylinder.

• This process repeats for each cylinder in the engine.

• Examples of 4 stroke...read more

Theory of machine deals with the study of mechanisms and their movements.

• Theory of machine focuses on understanding the principles behind the operation of machines.

• It involves studying the kinematics and dynamics of mechanisms.

• Examples include gears, cams, linkages, and mechanisms like engines and robots.
