FAQ
What does MVP mean on this page?
An interactive sketch with formulas and parameters. Polished Ready labs are the full bench experience.
What does the “Single-rod rail model” lab practice?
Tune parameters and match readouts to the “Single-rod rail model” relations — useful for prep and demos.
Self-study or classroom?
Both — tune alone, or project “what if…?” demos in class.
Readouts don’t match the formula?
Check units and ranges, then substitute step-by-step from the formula panel.
