Abstract
IT has been known for many years1 that the resistance of a copper wire is increased by loading and that this increase of resistance is in excess of that which can be accounted for by the accompanying change of cross section. It seemed to be probable, therefore, that this phenomenon could be applied to the measurement of the frequency of longitudinal vibration of non-magnetic rods, since the method which has been described previously2 cannot be used for such rods.
