A simplification in the conditions for the zero-length-spring seismograph

Abstract

It has been found that for the zero-length-spring seismograph recently described the length of the arm need not equal the distance from the pivot to the point of attachment of the spring. The proof of the infinite period is given for the more general case, and the effect on the period of slight deviations from the conditions for infinite period is shown.
