Photoelastic Methods - Assignment ExampleThere has been recent methods namely Converging clean-cut Method, Scattered Light Method and freezing Method, which are used in direct application of three dimensional models. In the engineering field, this method of photoelasttic analysis of strive is important as it is used to calculate stresses under variant circumstances. A series polariscope involves an optical instrument that is used in performing the measurements of quantitative seam through photostress reflection photoelasticity method. The device is lightweight and compact and easy to operate. It is always designed for the tripod mounting or hand hold. It is always equipped to accommodate diverse special purpose accessories that adapt it to perform different tasks of measuring the strain with the photoelastic coatings.This experiment was conducted with a view to apply the photoelastic methods of measuring stress to get the set of the normal stress values of a beam and making a c omparison of the mensural stress values computed from the theory 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 stimulate was to use the Cantilever 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 end using a photostress ductile and clamped to the tables or benchs edge. Besides, the sought to measure the deflection using the telephone dial gage and the stress found by photoelasticity. The beam dimensions were taken and mounted to the needed fixed sponsor 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
