| Abstract: | The Young's elastic modulus of the wire(steel wire)is quickly and easily and accurately measured by CCD photo-electric measuring system. The measurement result of the Young's modulus is 1.982×1011 N/m2,the uncertainty of measurement result is 0.113×10-11 N/m2,the expanded uncertainty is 0.226×10-11 N/m2. |
