Hydraulics + Pneumatics Gym — Level 1
Level 1 builds the core language: pressure vs flow, why hydraulics feel “strong,” why pneumatics feel “springy,” and the basic purpose of common components.
- Pressure: force per area
- Flow: volume per time
- Hydraulic vs pneumatic: liquid vs air
- Basics: check valves, cylinders, simple causes of speed

Pressure is not flow. Flow is not pressure. Keep them separate and most questions become easy.
Lesson Before You Start
Hydraulics and pneumatics questions usually test whether you can reason about two fundamentals: pressure and flow. Pressure relates to force; flow relates to speed.
Force depends mostly on pressure and area.
Speed depends mostly on flow and area.

Press Start
Question 1 loads immediately.
Pressure = force/area. Flow = volume/time. Keep them separate.
After-Session Lesson: Pressure vs Flow
If you only remember one thing, remember this: flow mostly controls speed, and pressure mostly relates to force.
When Level 1 is solid, move to Level 2.
