I can classify structural loads and predict the deformation or failure they may cause.
POE Unit 2 • Lesson 2.2
Forces, Loads, and Aerospace Structures
Focus question: How do different loads change the way an aerospace structure deforms or fails?

Lesson Targets
What You Will Be Able to Do
Load-type analysis
Each scenario is classified by the dominant load and connected to a reasonable deformation or failure concern.
Activity Flow
How the Lesson Moves
Each step builds the structural reasoning needed for the lesson deliverable.
1. Observe the loading
Identify where forces enter and leave the structure.
2. Classify the effect
Distinguish axial, transverse, rotational, and twisting behavior.
3. Predict the risk
Connect the load to a likely deformation or failure mode.
Lesson Interactive
Classify the Structural Loads
Match each aerospace scenario to the dominant load acting on the highlighted component.

Tip: Name the dominant internal effect in the component, not merely the direction of the external force.
Aerospace Scenarios
| Scenario | Dominant load |
|---|---|
| Suspended payload cable | |
| Landing-gear compression strut | |
| Clevis pin across a joint | |
| Wing spar under lift | |
| Drive shaft transmitting torque |
Look for pulling, pushing, sliding, curving, or twisting behavior.
