Abstract
Generator method for measurement of modules of elasticity and shear of wood is in excitation in sample with free ends long and transverse vibrations, and elasticity modulus and shear modules are determined by resonance frequencies of vibrations. Vibrations with resonance frequency of sample are excited by means of amplifier with use of resonance properties of sample in generation circuit.
