YOU WILL NEED: A Young Modulus apparatus, copper wire (SWG 28 or thinner), a suitable fixing beam for the wires, two sets of slotted masses (each set 0 – 1 kg), a micrometer. In a particular reading, the student measures the extension in the length of the wire to be 0.8 mm with an uncertainty of $\pm 0.05$ mm at a load of exactly 1.0 kg. Alternative metal wires can be used of course. The Young Modulus is named after Thomas Young (1773 to 1829) who was a British polymath, contributing to our understanding of optics, physiology, and Egyptology, among other fields. A student performs an experiment to determine the Young's modulus of a wire, exactly 2 m long, by Searle's method. Young’s modulus is a numerical constant, named after the 18th-century English physician and physicist Thomas Young. 15 Young’s Modulus Aim: To calculate the Young’s modulus of elasticity of the material of a bar by the method of flexure. E = FL/eA where A is the cross sectional area of the wire. The Young modulus for the wire will be the gradient of the graph x L/A.
