I can identify simple machines and explain how they change force, distance, direction, or motion in an aerospace application.
POE Unit 1 • Lesson 1.2
Simple Machines in Aerospace Systems
Focus question: How do simple machines change force, distance, direction, or motion in aerospace systems?

Lesson Targets
What You Will Be Able to Do
Simple machine identification chart and concept sketch
Each aerospace example is matched to the correct simple machine and its force, distance, direction, or motion tradeoff.
Activity Flow
How the Lesson Moves
This page highlights the lesson elements you need for practice, evidence, and submission.
1. Inspect aerospace examples
Look for the geometry and contact points that reveal the simple machine.
2. Classify the mechanism
Distinguish levers, pulleys, wheel-and-axle systems, inclined planes, screws, and wedges.
3. Explain the tradeoff
State what the machine changes and what the user gives up in return.
Lesson Interactive
Classify Aerospace Simple Machines
Identify the underlying simple machine in each aerospace example. Focus on geometry and motion rather than the complexity of the full system.
Examples
- Cargo rolls up a loading ramp.
- A screw jack raises a test fixture.
- A hinged service arm rotates about a pivot.
- A cable system lifts a payload.
- A winch drum pulls a rover.
Identification Chart
| Example | Simple machine |
|---|---|
| Loading ramp | |
| Screw jack | |
| Hinged service arm | |
| Cable lift | |
| Winch drum |
Look for the defining geometry: slope, thread, pivot, cable path, or rotating radius.
Today’s Work
Main Deliverable
Simple Machine Identification Chart and Concept Sketch
Classify aerospace examples, then sketch one simple-machine application for the rover challenge.
- For each example, name the simple machine and the input/output motion.
- On the sketch, label the effort, load, pivot or contact point, and expected tradeoff.

Mission Debrief
One way today’s lesson connects to an aerospace mechanism or VEX rover system.
One type of evidence you could use to support a design decision.
One question you still have about mechanisms, energy, power, or the Unit 1 challenge.
