Q10. 4 stroke engine working

Ans.

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

Q11. Theory of machine

Ans.

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.
