The Pressure of a Blow1

Nature volume 88, pages 531536 (15 February 1912) | Download Citation



THE scientific analysis of a blow requires, first, the determination of the actual pressures or forces set up between the colliding bodies, and, secondly, an investigation of the distribution of these pressures and of their physicaf effects. The pressure produced by a blow does not differ in kind from that produced by any other agency, such as an hydraulic press, but it differs in degree because of its great intensity and of its extremely short duration, and these characteristics, as we shall see, have a marked influence on the effects which it produces.
