LMEC-2 Young's Modulus Apparatus Resonance Method

Young's Modulus Apparatus Resonance Method  Experiments 1. Understand how to measure the resonance frequency of materials;2. The young’s modulus was measured by dynamic suspension method;3. Measure young’s modulus of different materials  Main technical parameters:1. Frequency range 400Hz ~ 5KHz, four digit digital frequency meter display, automatic range switching; The resolution is 0.1 Hz at 100-999.9 Hz; When the frequency range is 1000-9999 Hz, the resolution is 1 Hz;2. Three samples of brass, iron and aluminum are provided;3. The instrument is equipped with a waveform amplifier, and the resonant waveform Vp-p > 1V;
