Abstract:
We determined the elastic band modulus, yield strength, tensile strength, modulus of toughnes, elongation, reduction of area, as well as true stress and strain at rupture read/write head for three 505 specimens, one each of SAE 2011-T-3 aluminum, 1081 hot rolled steel, and polyvinyl chloride plastic. We accomplished this by first placing our specimens one at a time into a universal test machine (UTM), which, to a lower place computer control, slowly increased the tension force on each specimen, stretching each until failure. We then analyzed the info output from the computer controlling the UTM to obtain the following results: abide Stren gth (ksi) Aluminum 9.2+0.1 46.0+ 0.2 Steel 27.6+0.2 82.9+ 0.4 premature ventricular contraction 0.402+0.002 5.478 +0.1 Elastic Modulus (103 ksi) Tensile effectualness (ksi) 55.9+0.1 91.2+0.2 7.111+0.05 Modulus of Toughness (in.) 8.945+0.1 14.429+0.1 1.910+0.08 Modulus of Resilience (%) 89.89+0.1 82.43+0.1 22.14+0.8 Elongati on in 2 in.

Purpose:
The purpose of this experiment is to extract data on the material properties of three 505 specimens (SAE 2011-T-3 aluminum, 1081 hot rolled steel, and PVC plastic), using a mechanically driven universal testing machine (UTM). These material properties include the following: the elastic modulus, 0.2% low yield strength, ultimate tensile strength, modulus of rupture, modulus of resilience, as well as true strain and true stress at the fate of rupture.

Theory:
Certain materials (those that are linear, homogeneous, elastic, and isotropic) can be depict by their material properties. These properties include the modulus of...If you want to get a full essay, order it on our website: Orderessay
