On the other hand, bond stiffness, the second subject, can be studied with the Instron Merlin, which is used for the 3-point bend test in different types of materials (Glass, Aluminum, Steel, and Tungsten). This test produces necessary values for a flexural modulus(Ef) for each material, which, when divided by bonds/area(1/cm2) is used to compare bond strengths between materials.

Next, we correctly placed the gas tube in the discharge power lamp, which sent voltage through the tube. From there, we used the computer software and adjusted the exposure (relevant to the light collecting fiber) and collected the data which shows the wavelength of light produced by the release of photons of each gas we observed (H2 and O2).
Using Flexural Modulus to Compare Bond Strengths The procedure to test the strength of a bond for certain types of materials, we used the Instron Merlin to apply a 3-point bend test. We selected our materials (Glass, Tungsten, Aluminum and Steel) to be tested one at a time. We took the rod of choice and appropriately placed it in the mechanical apparatus. We then applied more force using the machine and used the computer software to record our
