Which two measurements enable the strain of the wire to be calculated? A the unstretche length of the wire and the cross-sectional area of the wireB the unstretche length of the wire and the extension of the wireC the Young modulus of the wire's material and the extension of the wire...
一个是应力(stress),应力是等于拉力除以横截面积,这样就是单位面积的受力了; 另外一个是伸长比例(strain),等于伸长长度除以原始长度,即伸长的百分比。 由于stress已经去除掉了面积的干扰因素,strain去除掉了原始长度的干扰因素,我们对杨氏模量的定义即为: 杨氏模量是只和材料相关的物理量,其数值越大,说明在变形的时...
Young's modulus assess how a polymer responds to external forces. See typical stiffness values for various plastics to guide your material selection.
Stress, Strain and Young's Modulus Stress is force per unit area - strain is the deformation of a solid due to stress. Stress Stress is the ratio of applied force F to a cross section area - defined as "force per unit area". tensile stress - stress that tends to stretch or length...

a convenient parameter is the ratio of the stress to the strain, a parameter called the"Young's modulus" or "Modulus of Elasticity" of the material. Young's modulus can be used to predict theelongation or compression of an object as long as the stress is less than the yield strength of...
Young's modulus is a measure of the elasticity or extension of a material when it's in the form of a stress–strain diagram. It is named after Thomas Young.
(sometimes referred to as Modulus of Elasticity, meaning "measure" of elasticity) is an extremely important characteristic of a material. It is the numerical evaluation of Hooke's Law, namely the ratio of stress to strain (the measure of resistance to elastic deformation). To calculate Young's...
