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. Young's Modulus Measurement of Metal Wires Using FBG Sensor To work out Young's modulus, we require two things: the stress and the strain of the wire. 4.2. The equation for Young's modulus is: E = / = (F/A) / (L/L 0) = FL 0 / AL. It is better to make an S shape between the blocks. One end of the wire was clamped between two . Constantan - Wikipedia Young's Modulus - Definition, Formula & Example - VEDANTU By using an optical lever, the change in length can be measured. The force to stretch a thin wire to a certain percentage stretch will be much, much less than the force to stretch a thick wire to the same percentage stretch.

Starting with 100 g add loads in increments of 100 g to the wire up to 600 g total load. Measure and record the length of the wire from clamp to vernier. 32) is directly proportional to the strain it produces before the extension becomes 3.5mm. Stronger bonds generally result in higher stiffness; copper has relatively strong bonds due to its metallic bonding, (strong interactions between the metal ions and sea of delocalised electrons) so it has a fairly high young's modulus value of 110-128 GPa . It usually consists of 55% copper and 45% nickel. masses. WHAT TO DO: Set up the apparatus as shown in the diagram.

We had a whole apparatus in our physics room when we measured the Young's Modulus of a piece of wire. DOC Young modulus - schoolphysics The calculated results based on the experimental measurements showed that the average Young's modulus and residual stress of the electroplated copper films are 115.2 GPa and 19.3 MPa, respectively, while the Young's modulus measured by the nanoindenter for the same copper film with silicon substrate is 1101.67 GPa. Young's modulus is the measure of elasticity, equal to the ratio of stress acting on a substance to the strain produced. 32) is directly proportional to the strain it produces before the extension becomes 3.5mm.
