Institutional subscribers have access to the current volume, plus a To determine Young’s modulus of elasticity of the material of a given wire. RIS. The computer you are using is not registered by an institution with a subscription to this article. Specimens with larger l o and ρ present more obvious measurement errors for Young's modulus, but the effect of ΔT is not significant. By comparing the effects of uniaxial tensile load on the change of the deflection curve with gravity, the relation between the actual and directly measured tensile Young's modulus is obtained. Risk Assessment 6. The Young Modulus is also known as Young's Modulus or the elastic modulus or tensile modulus.. Technol. Young's modulus measured by uniaxial tensile testing is affected by many inevitable factors, such as misalignment of the tensile axis [6–9], initial residual stress and clamping position . To understand how Searle’s apparatus is used to determine Young’s modulus of elasticity of the material of a given wire, read the below experiment.

Furthermore, the quantitative effects of ideal gage length l o , temperature change ∆T and the density ρ of the specimen on the modulus difference and modulus ratio are calculated. Furthermore, the quantitative effects of ideal gage length lo, temperature change ΔT and the density ρ of the specimen on the modulus difference and modulus ratio are calculated. In order to analyze and calculate the measurement error of the tensile Young's modulus, the effects of gravity and temperature changes, which would respectively lead to and intensify the bending deformation of thin specimens, are considered as influencing factors.
