10 4/21/99 Problem 14.7 in text
11 4/26/99 Plot the strain versus time AND stress versus time for the data given in sgage.txt.  The bridge voltage is 2.5 V, the gage factor for the strain gage is 2.055, and the dimensions of the bar are 1/8 inch X 1.5 inches.  The material is steel, and the negative signs on the offset voltages should be deleted (it's just a polarity issue).  Assuming that the loading was 1000 lbs +/- 400 lbs, compare the peak, minimum and average stresses computed based on the applied load and the stresses computed based on the measured strains.
