Unformatted text preview: about a substance from tensile testing. The point of failure is the most interesting and is typically called its " Ultimate Strength ". This experiment required a tensile testing machine, extensometer and three specimens for testing (Steel Rod, Aluminum 6061 T6, and Acrylic). The gage length of each specimen was measured, around 2 inches, marked with a red permanent marker, and recorded. Using a vernier caliper, we measured and recorded the gage diameter for round specimen such as the steel rod or the width and thickness for flat specimens. Next, we positioned the cross-head properly in relation to the height of the specimen and secured it between the upper and lower wedge type grips of the machine. After zeroing the extensometer, the tensile test was then ran until the stretching went to fracture. The fractured specimen was then removed and measurements of the diameter or width and thickness were recorded....
