stress strain, Mechanical Engineering

Assignment Help:

1. Determine young''s modulus using first 20 data points

2. Determine yield strain and yield stress based on -0.1 offset

3. Determine max(or min) stress.

4. Determine toughness

Display all above properly

On single graphm draw followings

5. Draw graph of original data with blue *

6. Draw initial regression using first 20 data points with red

7. Draw -0.1 offsetted regression line with green

Have another graph.

8. Draw 10 original data points around intersection with blue *. (for example, if intersection happens between data 60 and 61, plot original data from 56-65)

9. Draw line between two original data points before and after interseation with red line (for example, datat points between 60-61). Only between two data points

10. Draw offsetted regression line using 10 data points above with green line (for example, 56-65)
