Elasticity is a property of an object or material which will restore it to its original shape after distortion. Table (set up for data collection) Aim To determine Young’s modulus of elasticity of the material of a given wire. Light fr… How to determine Young Modulus of A wire by Experiment? It quantifies the relationship between tensile stress (force per unit area) and axial strain (proportional deformation) in the linear elastic region of a material and is determined using the formula: Young's modulus (E or Y) is a measure of a solid's stiffness or resistance to elastic deformation under load. More than 60,000 people in the United States are over the age of 100, and there are enough people over the, Nathaniel Hawthorne’s short story “Young Goodman Brown” is an intriguing story of mystery that mingles with faith and sin.

After each new weight check that the wire returns to its original length. This empirical relation is known as Hooke’s law. Young's modulus can be expressed as. Young’s modulus is also termed the modulus of elasticity. � Apparatus: Experimental set up, a spirit level, a meter scale, a screw gauge and a vernier caliper. Young's Modulus. Early Adulthood In this paper I want to talk about the diversity of adult lifestyles. Resources. Young’s Modulus or Elastic Modulus or Tensile Modulus, is the measurement of mechanical properties of linear elastic solids like rods, wires, etc. Clamp the copper wire across the bench using the G clamp and the wooden blocks. Background information (what is Young’s Modulus, how do we use a stress strain curve to determine it, etc) 3. Experiment No. 11, 2016. A new experimental method for evaluating Young’s modulus of rust layer has been proposed by simply-supported 4-point bending tests. 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.

Young’s modulus of steel is 200 x 10 9 GPa. Some of these are Bulk modulus and Shear modulus etc. Measurement of Young Modulus. 2 Theory Speaking loosely, if we were to press on any object from all the sides, the The Theory Before we move ahead, do you know what a Searle’s apparatus is? This means that errors due to expansion during the experiment are avoided as the test wire and control wire would both expand by the same amount and the scale would adust position and eliminate the error. = 4 3 3 ( ) Nm-2 2. Youngs modulus experiment apparatus setup is a complete system used to determine Young`s modulus of elasticity of materials of the given samples by bending. M is the bending moment. The wire suggested will have a diameter of 0.40 mm or less). : Date: SINGLE CANTILEVER Aim: To determine the youngs modulus of a material (q) by single cantilever. In solid mechanics, Young’s modulus is defines as the ratio of the longitudinal stress over longitudinal strain, in the range of elasticity the Hook’s law holds (stress is directly proportional to strain). The formula of young’s modulus is stress by strain. Young's modulus, the Young modulus or the modulus of elasticity in tension, is a mechanical property that measures the tensile stiffness of a solid material. I K L � � � � � � > G I y z ~ � � � � � � � � � � � � � � � ����������������������ئ���̰��榸��氢����������� Aim of this experiment is to find the Young's modulus of the given material by uniform bending using pin and microscope method. 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. Apparatus: Experimental set up, a spirit level, a meter scale, a screw gauge and a vernier caliper. Set up (diagram or description) 4. Load the wire carefully and for each weight (F) record the extension (e) of the wire using the vernier scale. E = FL/eA where A is the cross sectional area of the wire. Practically, MPa (megapascal), i.e., N/mm 2, or GPa (gigapascal), i.e., kN/mm 2, are the units used. Theresults of this experiment demonstrate that there is a positive correlationbetween the load of the couples and the deflection of the steel beam. Young’s double-slit experiment uses two coherent sources of light placed at a small distance apart, usually, only a few orders of magnitude greater than the wavelength of light is used. I, The numbers are astonishing. Thomas Young postulated that light is a wave and is subject to the superposition principle; his great experimental achievement was to demonstrate the constructive and destructive interference of light (c. 1801). Viva voce. 15 Young’s Modulus Aim: To calculate the Young’s modulus of elasticity of the material of a bar by the method of flexure. Use the blue tag to act as a marker for the convenience of the measurement. 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. Unit of stress is Pascal and strain is a dimensionless quantity. Background information (what is Young’s Modulus, how do we use a stress strain curve to determine it, etc) 3.

Method: Clamp the copper wire across the bench using the G clamp and the wooden blocks. Measurement of the Young modules. Rather than using a note card to split the single beam into two coherent beams, a carbon-coated glass slide with two closely spaced etched slits is used. There are some other numbers exists which provide us a measure of elastic properties of a material. 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. Young’s modulus is a numerical constant, named after the 18th-century English physician and physicist Thomas Young. Description of Searle’s Apparatus Construction.
