Yield Strength  
scene 7 of 10
The graph plots stress in p s i versus strain in inch per inch. The horizontal axis ranges from 0 to 0.1 and the vertical axis ranges from 0 to 80,000. The graph starts at the bottom left of the viewing window at the origin, goes up and to the right with constant steepness till the point (0.050, 50,000). The graph then goes up and to the right with a reduced positive slope till (0.1, 60,000). A straight line is drawn passing through (0, 0) and (0.040, 43,700) and it overlaps the linear portion of the curve. Another straight line is drawn between the points (0.02, 0) and (0.074, 56,000). The interval from the origin to the point (0.02, 0) is marked 0.2 percent.

Begin on the strain axis at the specified permanent set. Construct a line parallel to the initial elastic modulus line.
