| To R.{Sir Henry Royce} from EFC. C. to CJ. " " E.{Mr Elliott - Chief Engineer} X. 1775 EFC3/AT13.3.18. RE PERIODICITY OF SIMILAR VIBRATING SYSTEMS OF VARYING DIMENSIONS. With reference to the point we were discussing we make out that the periodicity of similar mechanical systems varies inversely as the first power of their linear dimensions, that is to say the period varies directly as this first power.
