experamental part presentation

Report requirements:

1 - Main purpose of laboratory work - to study methods of theoretical and experimental determination of bending stresses

2 - to draw stress distribution in bending (highlighted part at slide No 4);

3 - to draw experiment scheme (slide No 6);

4 - to draw general view of strain gauge (from slide No 8);

5 - to calculate theoretical bending stresses (according to formulas on slide No 4) for each sensor;

6 - to calculate real bending stresses (according to formulas on slide No 11) for each sensor;

7 - to find the relative error of stress determination delta_sigma in % (according to formulas on slide No 11);

8 - to draw real bending stress distribution diagram (like on slide No 4);

Summary:

1 - according to the purpose of laboratory workshop;

2 - according to results: to write values of theoretical and experimental bending stresses, to show the stress determination relative error values and to mark maximum relative error value;
