Unformatted text preview: strain) difference. b. Part 2: Repeat measurements of strain at fixed end displacements. i. Take the beam through a sequence of fixed displacements (5 total) from zero applied displacement to some reasonable maximum value for your set-up. ii. Repeat the displacement sequence 7 times, recording data for each run. iii. Document measurement drift by recording the values of strain after all the measurements are complete and the beam is unloaded. 3. Analysis a. Develop equations that predict strain at the location of the gage as a function of end displacement . Note1 : Use SI units throughout your work. Note2: You will be asked to do uncertainty analysis for your calculations. Make sure you have enough information to do this. See that “Uncertainty Analysis” document on the website....
