A disk-shaped body can only have
"single-plane" or static unbalance
|
| Because this rotating body is rather thin (shaped like a
disk), both Weight A and Weight B appear to be located in the same plane
of rotation.
(It is the same condition as in the next picture, with both weights in
the same plane of rotation)
Centrifugal forces generated by both weights are acting in
the same plane of rotation.
Because of this, the combination of both weights acts as if it were
indeed combined to one weight.
The Result:
Static Unbalance

unbalance, regardless of the shape of the rotating body, can be
detected and measured with a static or non-rotating balancer |
