Introduction: |
For the simulated materials testing we were given 4 materials to test. We used mild steel, aluminum, cast iron, and copper. We would individually take a material, and test the elastic point, breaking point, and stress point.
|
Testing: |
For the mild steel it doesn't break until the extension of about 14mm. It also has a elasticity point.
The aluminum doesn't break until about 23 mm, and there is a stress point. The elasticity point occurs at about 1 mm of extension. Cast iron doesn't have a elasticity point or a stress point. It broke at about 0.05 mm of extension. Copper has a elasticity point and stress point. Copper doesn't break until 17 mm of extension. |
Take-a-way: |
My biggest take-a-way was learning the way a material can affect many variables of your design. For example if I wanted to use a material that had more elasticity I wouldn't use cast iron or mild steel.

Below are pictures of the results for each of the materials tested.
