The formula of young’s modulus is stress by strain. Theory: If a light bar of breadth band depth dis placed horizontally on two Knife-edges separated by a distance L, and a load of mass m, applied at the mid-point of the bar, produces a depression lof the bar, then Young’s modulus Yof the material of the bar is given by 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. It relates stress (force per unit area) to strain (proportional deformation) along an axis or line.The basic principle is that a material undergoes elastic deformation when it is compressed or extended, returning to its original shape when the load is removed. Animation. Set up (diagram or description) 4. This empirical relation is known as Hooke’s law. Difference of flexural rigidities between two steel plate beams with and without corrosion upon is supposed to present the mechanical properties of rust layer. Then the graph can be analysed to determine E. Apparatus: Experimental set up, a spirit level, a meter scale, a screw gauge and a vernier caliper.

Early Adulthood In this paper I want to talk about the diversity of adult lifestyles. Light - Light - Young’s double-slit experiment: The observation of interference effects definitively indicates the presence of overlapping waves. Young's modulus (E or Y) is a measure of a solid's stiffness or resistance to elastic deformation under load. Young’s Modulus or Elastic Modulus or Tensile Modulus, is the measurement of mechanical properties of linear elastic solids like rods, wires, etc. Use the blue tag to act as a marker for the convenience of the measurement. Practically, MPa (megapascal), i.e., N/mm 2, or GPa (gigapascal), i.e., kN/mm 2, are the units used. 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.
