Static Balance: - correct answer when its mass centerline coincides with its
geometric centerline or axis of rotation. If it doesn't, the gravitational forces will produce a moment that
tends to rotate the rotor when it's at rest, causing an imbalance.
imbalance is a car tire.
To correct static imbalance: - correct answer weights are typically added or material
is removed from the rotor in such a way that the center of gravity is brought back to the rotor's axis of
rotation.
Not addressing static imbalance can result in - correct answer vibrations, reduced
bearing life, increased energy consumption, and potential equipment damage when the machinery
operates.
Limitations of Static Balance - correct answer a rotor can be in static balance but
still be in dynamic imbalance due to the distribution of its mass in different planes. That's why, especially
for high-speed machinery, dynamic balancing is also crucial.
Dynamic Imbalance:
1.Description: - correct answer In a dynamically imbalanced rotor, the mass
centroids of two or more planes do not align with the rotor's rotational axis. This misalignment results in
forces that create vibrations when the rotor spins.
3. Structural damage to the equipment and its surroundings
4. Reduced operational efficiency5. Noise issues
Dynamic Imbalance:
