Research on Selecting the Length Measuring Instruments for Young’s Modulus
摘要
Abstract
The rational selecting of measuring instruments is one of key elements during designing experiments.This paper discus-ses the measuring Young’s modulus of tinsel by pulling and stretching method from the perspective of measurement uncertainty,intro-ducing a method of transforming the requirement of the indirect measurement uncertainty into the estimation of the uncertainty of direct measurements by the uniform distribution of the uncertainty principle,which is expected to provide a reference to design experiments to meet the requirements of measuring instruments.关键词
