Mechanical System
A set of physical components that convert input force and motion into a desired output.
Input–Process–Output Systems
Mechanical systems are made up of three key elements:
- Input: The energy, force, or data introduced into a system.
- Process: The transformation or manipulation of the input to achieve a desired outcome.
- Output: The final result or product of the system's operation.
This model is not limited to mechanical systems, it applies to digital, biological, and organisational systems as well.
Inputs
- Energy Sources:
- Electrical: Powers motors and actuators.
- Mechanical: Includes human force or gravitational energy.
- Hydraulic/Pneumatic: Uses fluid or air pressure.
- Sensors and Data:
- Temperature Sensors: Trigger cooling systems.
- Pressure Sensors: Regulate hydraulic systems.
In a car engine, the input includes fuel (chemical energy) and air (oxygen) mixed in precise ratios.

Processes
- Transformation of Energy:
- Combustion: Converts chemical energy to mechanical energy in engines.
- Electromechanical Conversion: Motors transform electrical energy into motion.
- Control and Regulation:
- Feedback Loops: Sensors adjust processes in real-time.
- Valves and Switches: Regulate flow and pressure.
- Mechanical Operations:
