Abstract
The present work gives the results of measurements of the modulus of elasticity and the losses in ebonite by a resonance method. These magnitudes are determined as functions of the temperature for two specimens. At t=19°C, the resonance frequency of one of the specimens was 2784 Hz, of the other 1145 Hz. At these frequencies and higher temperatures ebonite is highly elastic. It is shown that the transition to this state at sound frequencies takes place at a temperature 47° C higher than by the static method.Keywords
