Every day the lab tests five specimens, each in a different rig: bend, tensile, torsion, column and pressure vessel. Same tests for everyone. Answer well and your specimen holds. Miss, and watch it fail.
- 1Identify: read the clues and name the material, machine, structure, law or person.
- 2Dimension check: name the quantity from its SI units.
- 3Sort it: put four values in mixed units in order.
- 4Odd one out: three share something. Find the one that doesn’t.
- 5Calc: work out a real engineering problem. Within ±2% passes. The Tools tab has a calculator, a formula sheet and a notebook.

Every miss or skip adds load to the specimen. Five rounds, 15.0 max.
Weekly curve: Monday and Tuesday are a light load, Friday is a heavy load, other days are standard.
Feedback: wrong Identify guesses tell you if you’re in the right category, and Dimension guesses tell you how many exponents match. In Calc, being within 10% after three tries still earns 1.0.
