ResumoAn electronic apparatus is described for the determination by a resonance method of Young's modulus and the modulus of rigidity of materials in the form of cylindrical rods. Results can be obtained at strains as low as 109. The method of calculation of the moduli from the observed resonant frequencies is given.
