Chase Machemehl November 8, 2007 Mrs. JoAnn Scales Section 10, Thursday 1-4pm Materials Science and Engineering Vanderbilt University Nashville, TN 37235 Hoop Stress Dear Mrs. Scales, Results of the laboratory experiment performed on Thursday, November 1 are included here. The objective of this experiment was to effectively measure the applied stress on a soda can using a strain gage. Because the soda can is mostly cylindrical and it has thin walls, it can be idealized as a thin walled cylindrical pressure vessel. Thin walled vessels can be subjected to hoop stress. In this case, the can was placed in three different scenarios and then analyzed using a strain gage. To prepare and apply the strain gage for the soda can, students followed these steps: Abrade a small area using 230-grit sand paper Cleanse the area with methanol and a q-tip Place the strain gage with a piece of tape Prepare the surface and the strain gage with M-Prep Apply M-Bond to the application site Apply Pressure for one minute
