Discussion
· Answer the discussion question from instruction under section “Manual tester: results, analysis, and reporting”
3. Polariscope (22 points)
Procedure
Briefly explain what instrument were used, what sample(s) were tested, what was measured, how the measurements were taken, etc.
Results
· 3 photos of the first sample
o Photo of the sample with no load
o Photo of the sample where the stress starts to appear (Mark the region where stress starts to appear)
o Photo of the sample with maximum load (Mark the region where high stress starts to appear)
· 3 photos of the second sample
o Photo of the sample with no load
o Photo of the sample where the stress starts to appear (Mark the region where stress starts to appear)
o Photo of the sample with maximum load (Mark the region where high stress starts to appear)

Appendix:
MATLAB code
* Do not use first person in technical lab reports! i.e., do not use “I” or “we”.
* Figures should be labelled by figure number, included in the body of the report and include legends, if appropriate.
* Graphs are figures and therefore should be numbered consecutively within the body of the report. Both axes on a graph must be labeled with units.
* Tables should be labeled by table number and included in the body of the report. Note that it is preferable to have Figures and Tables close to the text where they are discussed so copy and paste them into the body of the report.
