The following chart gives ultimate strength, yield point and modulus of elasticity data for steel and iron. In this region, the elongation of the bar is directly proportional to the tensile force and the length of the bar and inversely proportional to the cross-sectional area and the modulus of elasticity.Up to a limiting stress, a body will be able to recover its . 198. This is called the Young Modulus, E, of the material. All types of Cu/Mo/Cu sheets can be stamped into components. It is used to describe the elastic properties of objects like wires, rods or columns when they are stretched or compressed. The more the value of elastic modulus means the more elastic the material is. Young's modulus is also termed the modulus of elasticity. Its young are of copper wire. In this experiment, The Young's modulus of copper will be mesured . Young's modulus is a numerical constant, named after the 18th-century English physician and physicist Thomas Young. While it is suited to many applications most centre around its excellent electrical conductivity (e.g. Answer (1 of 2): For fluids (liquids and gases like water and air) you should use bulk modulus instead of Young modulus to describe their mechanical properties. If the treatment is made . Youngs Modulus is a Measure of Stiffness. Choi et. This sample essay on Copper Young's Modulus offers an extensive list of facts and arguments related to it.
