Definitions
- A component of an engine that moves back and forth inside a cylinder to convert pressure into mechanical energy. - A device used in pumps to create pressure by moving up and down inside a cylinder. - A part of a firearm that moves back and forth to eject spent cartridges and load new ones.
- A device used in plumbing to unclog drains or toilets by creating suction. - A component of a syringe that is pushed down to expel the contents. - A part of a pump that moves up and down to create pressure.
List of Similarities
- 1Both are components of mechanical devices.
- 2Both involve movement in a straight line.
- 3Both create pressure or suction through their movement.
- 4Both can be used in pumps or engines.
- 5Both have cylindrical shapes.
What is the difference?
- 1Function: Piston converts pressure into mechanical energy, while plunger creates suction or pressure.
- 2Usage: Piston is used in engines and firearms, while plunger is used in plumbing and medical devices.
- 3Direction: Piston moves back and forth inside a cylinder, while plunger moves up and down.
- 4Shape: Piston has a flat top and a cylindrical body, while plunger has a narrow stem and a wider base.
- 5Connotation: Piston is associated with power and force, while plunger is associated with unclogging and suction.
Remember this!
Piston and plunger are both mechanical components that involve movement in a straight line. However, the difference between piston and plunger is their function and usage. A piston converts pressure into mechanical energy and is used in engines and firearms, while a plunger creates suction or pressure and is used in plumbing and medical devices.
