When you can't use dials to measure misalignment, can you use the cross dial formula with feeler gauges or calipers?

The use of dials, such as dial indicators, is the preferred method for measuring misalignment due to the precision and direct readouts they provide. When dials are not available, measuring misalignment using feeler gauges or calipers does not yield accurate results corresponding to the parameters typically needed for alignment. The cross dial method specifically relies on certain geometrical and mechanical principles that don’t translate well with the tools mentioned in the other choices.

Utilizing feeler gauges or calipers may provide rough estimates of gaps or spaces, yet they lack the capability to assess angular misalignment or shaft alignment accurately, which are crucial for ensuring proper equipment function and reliability.

While there may be conditions in which basic measurements could be taken to inform rough adjustments, these methods do not effectively replace the precision required, which leads to an answer that supports the notion that accurate alignment measurement cannot be achieved without dial indicators. Thus, the response indicating 'No' correctly highlights that such methods do not meet the stringent accuracy requirements necessary for effective misalignment assessment.
