| Abstract: | In order to overcome the limitations of common methods for measuring modulus of elasticity(Young's modulus),a novel method for measuring the modulus of elasticity of a metal wire with capacitive displacement sensors is presented.The measurement principle,apparatus,and manipulation are introduced,the testing results given,and the errors in measurement discussed.The measured value is consistent with that given in relevant tables.The method has some advantages over conventional methods and can be used for meas... |
