Lab 2 Grading Explanation
If you have questions about the correct programming approach, or what the graphs should look like for your group's particular data, please contact the TA (Trevor, trevor.lujan@utah.edu) directly.

Lab 3 Instructions

Note - TA has curve-fit the data for all groups now.  ALL WEDNESDAY GROUPS SHOULD USE "ta_harmonic.txt".

split.m, and sub-function nozero.m - Matlab file used to pre-process the "ta_harmonic.txt" file - will need to be modified before using with data for the lab groups.

Sample dimensions corresponding to data set "ta_harmonic.txt":  Width:  2.21 mm; Thickness: 3.08;  Length:  15.60
Strain levels corresponding to data set "ta_harmonic.txt":  2%, 4%, 6%

Data, Wednesday
    Group 1:  Use ta_harmonic.txt
    Group 2:  Use ta_harmonic.txt
    Group 3:  Use ta_harmonic.txt
    Group 4:  Use ta_harmonic.txt
Data, Thursday
    Group 1: h1_harmonic.txt
    Group 2: h2_harmonic.txt
    Group 3: h3_harmonic.txt
    Group 4: h4_harmonic.txt
