---------------------------- 📏📐📏Operation Principle 📏📐📏 ----------------------------------
How do things work?
4 types
- Mechanical
- Electrical
- Chemical
- Magnetism

Enables and enhances the principle
In order for the identified operating principle can work efficiently
A mechanism
- In ENGINEERING view is the combination of moving components to transform the input forces and movement into a desired set of output and movement.
- In CHEMISTRY view is the step by step of sequence of elementary reactions by which overall chemical change occurs.
6 essential mechanisms in functional prototypes
1. Actuators
A device that makes something move or operates it
2. Cams
A mechanical device is used to convert the rotation of a shaft into simple or complex reciprocating linear motion.
3. Gears
A device used to
Increase torque from the driving equipment (motor) to driven equipment
Reduce the speed generated by the motor
Change the direction of the rotating shafts
4. Lever
An effort applied to one end of the beam will cause a load to be moved at the other.
Allowing a small input force to exert a much higher output force.
5. Ratchets
A mechanism that drives to limit either rotary or linear motion to only one direction.
6. Springs
A mechanism that has the capacity to absorb, store and release energy through a change in shape.
The amount of energy generated by the change in shape is governed by Hooke’s Law (within the elastic limitations of materials)
