Abstract
THE stresses set up in a rotating disk appear first to have been considered by Maxwell1, and the solution adopted by many engineering text-books2 shows that an axial hole, however small, halves the strength of the disk. This result, which is repugnant to physical intuition, does not appear to have been tested experimentally. During the design of an ultra-centrifuge3 to be used for separating isotopes, we had to investigate the effect of a small axial hole on the bursting speed of the rotor, and it is interesting to compare our results with the above theory.
