Abstract
Values of Young's modulus have been obtained for commercial 60-40 brass, 0.9% carbon steel, Vitreosil silica, super-purity aluminium and alumina by determination of the resonance frequencies in `free-free' transverse vibration and an attempt made to correct the results for shear and rotatory inertia. However, it was found that an empirical correction depending linearly on the stiffness ratio gives a more dependable result than the various suggested theoretical corrections.
