It is to be mentioned that Young's modulus values of the 1 min and 1.5 min heat treated samples are close to Young's modulus values of cementite reported in Ref. Specimens with larger l o and ρ present more obvious measurement errors for Young's modulus, but the effect of ΔT is not significant. ASTM E1876-97 describes how the resonant frequencies of elastic materials are excited by striking a rectangular or cylindrical bar which is free to vibrate. The aim of this section is to derive a specific subclass of the class of models where the shear and Young’s moduli depend linearly on the pressure, and to describe the experiments in Jones Parry & Tabor (1973) and Paterson (1964) up to around 4000 atm.

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. Elasticity is a property of an object or material which will restore it to its original shape after distortion. Experiment No. Our value for young’s module is 1.04*10^10, (2016, 11). It is a measure of the stiffness of a material that is independent of the particular sample of a substance. This empirical relation is known as Hooke’s law. Our aim is to determine the Young’s modulus of elasticity of the material of a given wire using Searle’s apparatus. The slide with its slits is most commonly purchased from a manufacturer who provides a measured value for the slit separation distance - the d value in Young's equation. 3. Clamp the copper wire across the bench using the G clamp and the wooden blocks. In the experiment in the video above, we measured the Young’s modulus of some copper wire which does not extend very much. Cite this Simulator: Developed by Amrita Vishwa Vidyapeetham & CDAC Mumbai. Light - Light - Young’s double-slit experiment: The observation of interference effects definitively indicates the presence of overlapping waves.
