POE Unit 2 • Lesson 2.17

Prototype Build and Load Testing

Construct the payload support structure, record mass and dimensions, run load tests, and document failure or performance limits.

Lesson Snapshot

Student Objective

I can build a structural prototype safely and test it using a repeatable procedure.

Main Activity

Construct the payload support structure, record mass and dimensions, run load tests, and document failure or performance limits.

Deliverable

Prototype photos and load test data

Tools / Materials

Approved build materials, hand tools, adhesives/fasteners, weights or force gauge, safety equipment

1ProblemUnderstand the challenge and why it matters.

A design is not proven until it is built and tested under controlled conditions. The goal is to learn how the structure behaves, not just to avoid failure.

2ConceptLearn the engineering idea or skill.

Prototype testing compares expected behavior to actual performance. Teams should record mass, dimensions, load, deflection, failure mode, test photos, and any unexpected behavior.

3ApplyUse the skill in a guided task.

Build your payload support structure, inspect it for safety and quality, and test it using the class procedure.

4DocumentRecord your evidence and decisions.

Record prototype photos, measurements, load-test results, deflection data, and failure or success observations.

5ReviewCheck quality and identify your next step.

A failed prototype can still be a successful engineering test if the data explains what happened and what should change next.
