Operating principle:
The standard implements a method for reproducing constant angular acceleration by transforming the projection of the acceleration of gravity using a screw-type aerostatic support with minimal parasitic friction.
Composition of the standard:
- A stand for reproducing constant angular acceleration by converting the acceleration of gravity into constant angular acceleration;
- A ring laser measuring system;
- A magnetic drum for transferring unit size;
