isc M record the moment of the area about the axis XX, and those in thedisc I record the moment of inertia about XX. The machine runs along aguide rail which is set parallel to the chosen axis by the distance bars indicated.With the Amsler integrator it is necessary to trace completely round a… … Fig. 11.
