The tensile properties of these metals will be contrasted and the properties will be compared with those in reference books. II. INTRODUCTION The tensile test is the primary test used in determining the mechanical properties of materials.  From this test, it is possible to determine the yield strength, tensile strength, modulus of elasticity,  and ductility of a given material. This type of data is essential for mechanical and structural  designs and is usually compiled in materials handbooks for commercially available materials.  III. EXPERIMENTAL Materials and Apparatus Instron Tensile Test System (Series 3369, Figure 1 ) Four tension test specimens – aluminum (2024-T4), copper (C11000), brass (C36000), and steel (1010 cold-rolled) (see Figure 2 ) Rockwell Hardness Tester Vernier caliper

    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.
