Página 4 - A ratio of t ; and the numerical value — will vary inversely a as l, and directly in the duplicate ratio of t. In other words, the unit of acceleration varies directly as the unit of length, and inversely as the square of the unit of time; and the numerical value of a given acceleration varies inversely as the unit of length, and directly as the square of the unit of time. It will be observed that these have been deduced as direct consequences from the fact that [the numerical value of] an acceleration...

Special names, if short and suitable, would, in the opinion of a majority of us, be better than the provisional designations "CGS unit of . . . ." Several lists of names have already been suggested ; and attentive consideration will be given to any further suggestions which we may receive from persons interested in electrical nomenclature. The
Página 216 - September 22nd, 1881:— 1. For electrical measurements, the fundamental units, the centimetre (for length), the gramme (for mass), and the second (for time), are adopted. 2. The Ohm and the Volt (for practical measures of resistance and of electromotive force or potential) are to keep their existing definitions, 102 for the Ohm, and 108 for the Volt.
Página 50 - ... large deformations without receiving a permanent set, is said to have wide limits of elasticity. A body which, like steel, opposes great resistance to deformation, is said to have large coefficients of elasticity. Any change in the shape or size of a body produced by the application of force to the body is called a strain; and an action of force tending to produce a strain is called a stress. When a wire of cross-section A is stretched with a force F, the...
Página 211 - FRS, and Professor EVERETT (Reporter). WE consider that the most urgent portion of the task intrusted to us is that which concerns the selection and nomenclature of units of force and energy ; and under this head we are prepared to offer a definite recommendation. A more extensive and difficult part of our duty is the selection and nomenclature of electrical and magnetic units. Under this head we are prepared with a definite recommendation as regards selection, but with only an interim recommendation...
