Publisher's Synopsis
Excerpt from The Screw Propeller: An Investigation of Its Geometrical and Physical Properties, and Its Application to the Propulsion of Vessels
The discovery of the surface of vanishing pressure, detailed in the second chapter, is important, as it affords an explanation of some curious pheno mena which have been observed in the practice of Screw Propulsion.
The investigation of the moment of inertia of the screw blade, as given in problem chapter ii., and its application to the determination of the accelerating forces acting on the blade of the Screw Propeller, are entirely new, as well as the results obtained, in the notes at the end of the second chapter, on a subject highly interesting both to the practical Naval Archi teet and the theoretical inquirer. The formulae for the area, pitch, radius of gyration, and moment of inertia of the screw propeller blade, and the table, computed at considerable labour, for their application in practice, will, it is hoped, be found useful to practical men.
