The greater the value of Young Modulus,the stiffer the object is. Young's modulus is an intensive quantity; it doesn't depend on the size (length, area, volume) of the material (you “divide that out”). Young’s modulus is the ratio of longitudinal stress and longitudinal strain. HISTORY. I have issues concerning setting youngs modulus to a realistic value like 10 GPa. )of a given spring Debangshu Mukherjee BS.c Physics,1st year Chennai Mathematical Institute 12.09.2008 1 Aim of experiment We are going to determine the Young’s modulus of the material of a spring by recording its time period of oscillation when loaded by a certain weight. Young's modulus, which is also known as the elastic modulus, is a mechanical property of linear elastic solid materials. This requires insanely small timesteps. Young's modulus is named after the 19th-century British scientist Thomas Young.However, the concept was developed in 1727 by Leonhard Euler, and the … In the documentatiom and in every thread on this question people say that it should not be bigger that 5e6 for si units or 5e5 for cgs. 2 Apparatus required OBJECTIVES. Aim of this experiment is to find the Young's modulus of the given material by non-uniform bending using pin and microscope method. I have a question regarding finding the Young’s modulus of a rod by loading a weight to the end and measuring the change in displacement. Notice that the definition of Young's modulus is quite similar to that for spring force; Young's modulus relates … Stress is applied to force per unit area, and strain is proportional change in length. The Young Modulus is named after Thomas Young (1773 to 1829) who was a British polymath, contributing of physiology, optics and egyptology, among other fields in 1807. If we look into above examples of Stress and Strain then the Young’s Modulus will be Stress/Strain= (F/A)/(L1/L) Young’s Modulus= Stress / Strain ={(F/A)/(L1/L)} The modulus of elasticity formula is simply stress divided by strain. Please keep in mind that Young’s modulus holds good only with respect to longitudinal strain. Young's modulus of the brick: View All: A brick of length 215mm, width 102.5mm and height of 65mm is stepped on by a man weighing 800N. Aim of this experiment is to find the Young's modulus of the given material by uniform bending using pin and microscope method. What is the strain on the brick! If this is true, then to remedy this, you will want to ramp your Young's modulus up gradually, possibly with high damping. I really can't figure how to calculate this one To experimentally determine a value of the Young modulus of a material. It defines the relationship between stress (force per unit area) and strain (proportional deformation) in a material. The modulus of elasticity, also known as Young's modulus, is a material property and a measure of its stiffness under compression or tension. If the Young's modulus is suddenly increased by several orders of magnitude, the inter-particle forces will be very high at the onset of your simulation, and therefore, you may experience some very high energies. 1 Pascal = 1 N/m 2 However, for most engineering problems it is fairly small unit, so it is convenient to work with multiples of the pascal: the GPa , and the MPa . Most commonly used unit of Young’s modulus is pascal, which is defined as force of 1N that is exerted on unit area. The Young's modulus of the brick is 20,000MN/m2.
