The phrase "a rigid stage" is correct and usable in written English.
It can be used to describe a phase or level of development that is inflexible or unchanging.
Example: "In the project, we reached a rigid stage where no further modifications could be made without significant consequences."
Alternatives: "a fixed phase" or "an inflexible level".
It is able to effectively constrain the parasitic rotation of all rigid stages and the cross-axis coupling of the motion stage.
This is good reading, although one gets that sense that, with some of the characters, Greenwald may be stuck at an earlier, more rigid stage.
Later on, in an episodic book with sections named for the stages of an epileptic seizure ("Onset," "The Rigid Stage," "The Convulsive Stage," "The Stage of Recovery"), Ms. Slater presents her most creative and wry bit of dissembling.
In order to prevent such a problem, the algorithm includes a rigid registration stage, which finds the relative displacement (in pixels) between each binary mask and the following one.
The play has also been frozen in time by Beckett's famously rigid stage directions.
As such, the fourfold method is of highest import, and it should be observed that it did not need to be applied in a rigid four-stage way.
The proposed approach is based on a systematic arrangement of rigid stages and compliant modules in a three-legged XYZ CPM system using the constraint spaces and the position spaces of the compliant modules.
A compliant mechanism can be decomposed into rigid stages and compliant modules.
Two analytical models, static approximate and static accurate, are derived for all translational displacements of rigid stages, and compared to a finite element analysis (FEA) model and experimental results for a case study.
If a compliant mechanism is at static equilibrium, all the rigid stages are also at static equilibrium under the influence of the variable and constant constraint forces.
