About this book
The Strength Of Rotating Discs ( With Special Reference To Steam Turbines)
Author: R. Gardner(Member)
Year: 1924
In treating of the strength of rotating discs for steam turbines, it is usual to begin by lamenting that mathematicians have no exact way ol calculating the stresses in discs of the forms actually used. Unfortunately the stresses in any part of any machine or structure cannot be calculated exactly; it is always a matter of approximation. The usual form of disc, which has its thickness inversely proportional to a power of the radius, 1s eminently suitable for practical purposes. It is not uniformly stressed throughout— the hoop stress is usually greater near the hub than near the rim. We are, however, generally limited by the requirement of a minimum thickness at the rim, and therefore, if we made the hoop stress uniform, the disc thickness at the hub would be inconveniently great.
