The mechanical resonance of quartz microfibers was investigated, pulled from a quartz rod. The investigation was made to qualify the method of obtaining Young's modulus of nanowires from their resonance frequency and geometry. The resonance frequency shift was calculated by an equation for a circular beam with a linearly varying cross-section. The results show that mean value from measurements of the fundamental resonance on 14 different microfibers is 70±6 GPa, which is close to 72 GPa, the Young's modulus of bulk fused quartz.
