What Critical Speed Means for Rotating Shafts
Cuándo aplica
Relate shaft stiffness and concentrated masses to a first natural frequency check before you chase balance or run near resonance.
Herramienta a usar
Estimate bending critical speed from stiffness and distributed mass—compare running-speed margins before detailed rotor analysis.

- 1Clarify the scenario, units, and governing assumptions before typing numbers.
- 2Run the linked calculator with conservative inputs and record what you changed.
- 3Compare against a second method, vendor data, or code limits when decisions matter.
Ejemplos
- Early screening before you invest in detailed modeling or vendor quotes.
- Teaching or design reviews where transparent assumptions matter more than precision.
Qué evitar
- Mixing metric and imperial without writing the conversion chain.
- Treating educational estimates as code-compliant sign-off.

FAQ
Is this a substitute for professional engineering?
No—use it to learn and screen options; qualified review still applies for compliance and safety.
Why might my numbers disagree with standards or vendor software?
Property data, rounding, and implicit safety factors differ. Treat this as transparent reasoning—then confirm with codes, datasheets, or licensed review when decisions bind.
