Photoelastic Methods - Assignment ExampleThere has been recent method actings namely meet Light Method, Scattered Light Method and freezing Method, which are workd in direct application of three dimensional models. In the engineering field, this method of photoelasttic analysis of emphasise is important as it is used to calculate stresses under different circumstances. A series polariscope involves an optical instrument that is used in performing the measurements of quantitative strain through photostress reflection photoelasticity method. The device is lightweight and compact and easy to operate. It is of all time designed for the tripod mounting or hand hold. It is always equipped to accommodate different special purpose accessories that adapt it to perform different tasks of beat the strain with the photoelastic coatings.This experiment was conducted with a view to apply the photoelastic methods of measuring stress to get the values of the normal stress values of a beam and ma king a comparison of the measured stress values com fix uped from the conjecture of elementary material strength. The study sought to compare theoretical values with measured values of the beam deflection. This study also sought to demonstrate the use and application of Maxwells law of reciprocal deflectionsIn this experiment, the focus was on beam analysis. It involved applying the photoelastic techniques, and testing the cantilever beam. The aim was to use the jut out beam to help understand the fringe by relating to the magnitude of strain. As often the case, the cantilever beam is always coated at one give up using a photostress plastic and clamped to the tables or benchs edge. Besides, the sought to measure the deflection using the dial gage and the stress found by photoelasticity. The beam dimensions were taken and mounted to the needed fixed support with the help of a C clamp. A single dialing indicator was put at the beams center and the other next to the free end
