Force Analysis of Trusses
The purpose of this experiment was to demonstrate bridge theory by placing a PASCO truss set (model ME-6990) under various loads and observing the resulting forces on the different members. These values could then be compared to the theoretical calculated forces.
Impact Toughness Testing
The purpose of this experiment was to calculate the impact energy of three different samples of 3D printed Poly Lactic Acid (PLA). Each sample of PLA had a different number of shells, which essentially determined how thick the walls of the sample were.
Yield Stress and Modulus of Elasticity
The purpose of this experiment was to determine the Modulus of Elasticity for an unknown specimen and then decide what the material of the specimen was. This was done using an Instron Tensile/Compression Tester (Model 4481) and the unknown test specimen that was in the shape of a thin rod whose initial diameter and length were measured.
