Q.1: Find out Young’s modulus value of a material whose elastic stress and strains are 4 N/m 2 and 0.Speech studied on both the phonetic and phonological levels of analysis. The force exerted by the object under tension Notations Used in the Young’s Modulus Formula We can also write Young’s Modulus Formula by using other quantities, as below: Get the huge list of Physics Formulas here The formula for Young’s Modulusįormula is as follows according to the definition: As we know that one part of the clay sample deforms more than the other whereas a steel bar will experience an equal deformation throughout. Also, Young’s modulus is used to find how much a material will deform under a certain load.Īlso, we must remember that the lower the value of Young’s Modulus in materials, the more is the deformation experienced by such a body. We can claim that Steel is a lot more rigid in nature than wood or plastic, as in its tendency to experience deformation under applied load is less. Its values in the factor of 10^9 Nm^ of different material are: Therefore the constant Young’s modulus applies only to linear elastic substances. It is also a fact that many materials are not linear and elastic beyond a small amount of deformation. Young’s modulus is defined as the mechanical property of a material to withstand the compression or the elongation with respect to its original length. Stress and strain both may be described in the case of a metal bar under tension.
We compute it by dividing It is computed as the longitudinal stress divided by the strain. Often we refer to it as the modulus of elasticity. It is a measure of the ability of a material to withstand changes in length when under lengthwise tension or compression. For example as in the case of a metal rod that after being stretched or compressed lengthwise returns to its original length. It describes the elastic properties of a solid undergoing tension or compression in only one direction. It was named for the 18th-century English physician and physicist Thomas Young. Young’s modulus, used as a numerical constant. Let us learn the interesting concept! Young’s Modulus Formula What is Young’s Modulus? In this article, we will discuss its concept and Young’s Modulus Formula with examples. This is due to the reason that it gives information about the tensile elasticity of a material. But the value of Young’s Modulus is mostly used. Some of these are Bulk modulus and Shear modulus etc. There are some other numbers exists which provide us a measure of elastic properties of a material. Young’s Modulus or Elastic Modulus or Tensile Modulus, is the measurement of mechanical properties of linear elastic solids like rods, wires, etc.
