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 “Pulley mechanical efficiency” lab practice?
Tune parameters and match readouts to the “Pulley mechanical efficiency” 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.
