    1. The critical speed of a shaft depends on following factors:

      • Shaft stiffness and support: This refers to how rigid the shaft is and how it’s supported by bearings. A stiffer shaft with strong bearings will have a higher critical speed.
      • Total mass of the shaft and attached parts: The heavier the overall rotating assembly, including the shaft and anything mounted on it, the lower the critical speed will be.
      • Unbalance of the mass: Any uneven distribution of mass around the shaft’s axis will cause wobbling and influence the critical speed. Higher imbalance leads to a lower critical speed.
