Unit 3 Wrap-Up: Motors, Gearboxes, and Mechanisms

Use a mechanism tradeoff sheet with a gearing calculation and test plan and the evidence you collected in this Unit. Do not answer from memory if your artifact gives you something more precise to point to.

Choose one response format: 75–125 words total, a one-minute recording, or an equivalent format available in your learning environment.

1. What did the evidence show? Name one result, dependency, measurement, trace, or behavior that your artifact makes visible.
2. What changed or became clearer? Identify one assumption you corrected, one tradeoff you understand better, or one part of your model you revised.
3. What remains uncertain? Name one question, risk, untested condition, or limitation you would investigate next.

Use at least two exact labels, values, device names, states, or test observations from your Unit artifact. “It worked” is not enough evidence.
