In dynamic balancing do we need to support the component on the machine in the same location as in assembly?

---

Yes, it is essential to support the component being balanced at the same or nearly identical location as the actual bearing supports used in its operation. This is because dynamic balancing involves both force balancing and couple balancing.

The couple is defined as the product of the force and the distance to the point of support. If the support location is changed, the forces acting on the component will also change, leading to inaccurate balancing results. Therefore, to replicate real-life operational conditions and achieve precise balancing, the component must be supported in a way that closely mimics its actual setup in assembly.

If the point of support is altered, the balance achieved will no longer remain valid, as the relationship between forces and distances will be compromised.

The Balance is no more valid if point of support is changed.
