I can translate a structural mission into measurable criteria, constraints, and evidence.
POE Unit 2 • Lesson 2.1
Unit Launch: Built to Survive
Focus question: How do structural engineers balance strength, stiffness, mass, safety, and evidence?

Lesson Targets
What You Will Be Able to Do
Payload support mission map
The map identifies the load, supports, load path, criteria, constraints, and proof required for success.
Activity Flow
How the Lesson Moves
Each step builds the structural reasoning needed for the lesson deliverable.
1. Decode the mission
Separate what the structure must do from the limits placed on the design.
2. Trace the load path
Show how the payload force travels through members and connections to the supports.
3. Define proof
Choose calculations and tests that could verify performance.
Lesson Interactive
Decode the Payload-Support Mission
Classify each statement so the team knows what defines success, what limits the solution, and what evidence must be collected.
Challenge Statements
Mission: Support a 20 N payload 150 mm above the base using no more than 45 g of classroom material. The structure must survive three tests and be documented with calculations and photos.
Classify the Requirements
| Statement | Type |
|---|---|
| Support 20 N | |
| Reach 150 mm | |
| Use no more than 45 g | |
| Survive three tests | |
| Calculations and photos |
Criteria measure performance, constraints limit the design, and evidence proves the claim.
Today’s Work
Main Deliverable
Payload Support Mission Map
Create one annotated mission map for the Unit 2 structural challenge.
- Label the applied load, supports, primary load path, and likely critical connection.
- List at least two measurable criteria, one constraint, and the evidence needed to defend the design.
