Abstract Beam analysis using photoelastic methods provides engineers with the data for values of stress and deflection on a beam. The objective of this lab was to apply photoelastic methods of stress measurement to obtain values of the normal stress in a beam, and to compare the measured stress values with values computed from elementary strength of materials theory. To compare measured and theoretical values of beam deflection, and to demonstrate Maxwell’s Law of Reciprocal Deflections. The beam was recorded for the deflections and the stresses. The results showed that when the load was applied at the end of the beam there was a greater deflection then when the load was applied at the middle of the beam. The results were used to calculate experimental stresses, theoretical stresses, and theoretical deflections. 3

Introduction Beams with aluminum and photoealstic plastic are a material that is used consistently in engineering projects. Different types of beams are used depending on the different circumstances. Deflection and stress are factors that an engineer should consider while using photoelastic beams. The objective of this lab was to apply photoelastic methods of stress measurement to obtain values of the normal stress in a beam, and to compare the measured stress values with values computed from elementary strength of materials theory. To compare measured and theoretical values of beam deflection, and to demonstrate Maxwell’s Law of Reciprocal Deflections. The photoelastic beam was recorded for its deflection and stresses. The data found was used to show that when the load was applied at the end of the beam there was a greater deflection then when the load was applied at the middle of the beam. The results were used to calculate experimental stresses, theoretical stresses, and theoretical deflections.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
