Hydraulic Machine – Mind Map

1. Definition

• A hydraulic machine uses a fluid (usually oil or water) to transmit force from one point to another using Pascal’s Law.

2. Principle Used

• Based on Pascal’s Law: Pressure applied to a fluid in a closed system is transmitted equally in all directions.

3. Working

• A small force applied on a smaller piston creates pressure in the fluid.
• This pressure is transmitted to a larger piston, generating a greater force.
• Thus, a hydraulic machine multiplies force.

4. Important Components

• Small piston (input)
• Large piston (output)
• Incompressible fluid (usually oil or water)
• Cylinder

5. Applications

• Hydraulic lift (used in garages)
• Hydraulic brakes (in vehicles)
• Hydraulic press (used in industries)
• Hydraulic cranes and excavators (e.g., JCBs)

6. Skills Students Learn

• Understanding force multiplication
• Applying physics in real-world systems
• Analyzing mechanical advantage
• Problem-solving using physics principles

7. Values Developed

• Scientific curiosity
• Appreciation for engineering and machines
• Awareness of safety and technology use
• Respect for innovation and design
