What this tool does
Force grows with the square of the rotational speed, which is why a small unbalance that is harmless at 500 rpm becomes destructive at 3000. Two grams out of balance at the rim of a car wheel is enough to feel through the steering.
Formula
F = m × ω² × r

Limitations
- The formula assumes ideal conditions: no friction losses, no air resistance and no efficiency losses unless you enter them.
- For work that must comply with a standard or be signed off, check the result against the applicable code and have it reviewed by a qualified engineer.
