Measuring young’s modulus of copper essay example for free studymoosecom repeat the experiment by using copper wire with different swg and take an average of the young’s modulus obtained so that we can estimate the value of young’s modulus of copper more accurately. In solid mechanics, young's modulus (e) is a measure of the stiffness of a given material it is also known as the young modulus , modulus of elasticity , elastic modulus or tensile modulus (the bulk modulus and shear modulus are different types of elastic modulus . Young's modulus as a function of temperature was determined by a dynamic method for single‐crystal sapphire and ruby and for polycrystalline aluminum oxide, magnesium oxide, thorium oxide, mullite, spinel, stabilized zirconium oxide, silicon carbide, and nickel‐bonded titanium carbide. According to the theory of elasticity the modulus of elasticity or young's modulus (thomas young) is denoted by e is defined for isotropic materials in addition with the shear modulus or the.
In part ii of this lab, you will hang weights on a copper wire and measure the stress and strain from that data you will compute young's modulus for copper and plot a stress vs strain graph similar to the one in figure 3. Modulus of elasticity is an important design factor for metals for calculations of elastic deflections room temperature modulus of elasticity values for some of the aluminum alloys, copper alloys, cast irons, various non-ferrous metals, steel alloys and titanium alloys are given in the following chart. Young's modulus data which fit the above equation craver and taylor (11, 12) describe apparatus for measuring the velocity of propagation of a mechanical pulse in a paper sample. The aim of this work was to obtain an accurate young's modulus using a resonance frequency measurement to accurately measure the young's modulus of copper foils and compare the results with the tensile young's modulus.
Their young’s modulus, yield stress, ultimate tensile strength, and elastic strain energy density 11 uniaxial testing for uniaxial tests, the displacement is typically held at a constant rate, and displacement. Measurement of the young modules aim: the aim of this experiment is to measure the young modules of copper wire method: clamp the copper wire across the bench using the g clamp and the wooden blocks. Under elastic conditions, a modulus of elasticity of a wire, called the young modulus e, is defined as the ratio of the tensile stress applied to a body to the tensile strain produced where e is expressed in n m-2 or pascal (pa.
