Focus question: How do mechanisms change or control motion in aerospace systems?
Distinguish linear, rotary, oscillating, and reciprocating motion. Explain how a mechanism changes direction, speed, force, or motion type. Connect motion choices to aerospace systems such as control surfaces, landing gear, or payload doors.
For the online work: a browser and your engineering notebook. Follow the activity’s materials list for any physical build, and get teacher approval before using equipment.
Suggested work block: 45–60 minutes. Physical builds and projects may span several classes; follow your teacher’s schedule.
Use this page with the lesson presentation, your engineering notebook, and the tools or evidence assigned for Classify Mechanisms by Motion.
You can identify motion types and explain how mechanisms transfer or transform motion.
Connect your response to the decision, evidence, or quality standard required for Classify Mechanisms by Motion.
This lesson is ready to move forward when the evidence meets this standard: Motion classifications describe what the parts actually do rather than only naming the device.
Mechanisms make motion useful and controlled.
Motion can be transferred, transformed, limited, or amplified.
A mechanism choice should match the function the system must perform.
Analyze examples to determine their input motion, output motion, and mechanical purpose.
Quality check: Motion classifications describe what the parts actually do rather than only naming the device.
Identify motion by following the path of the output component.
| System | Observed output motion | Classification |
|---|---|---|
| Access-panel hinge | Turns around a fixed axis | |
| Payload drawer | Moves straight in and out | |
| Cam follower | Moves repeatedly up and down | |
| Cooling fan | Turns continuously |
Submission standard: Motion classifications describe what the parts actually do rather than only naming the device.
