Transcribed Image Text:A cylindrical specimen of a steel alloy having a diameter of 12.8 mm and a gauge length of 50.8 mm is pulled in tension and generates the stress-strain relationship shown in the Figure below. Use this figure to approximate the ductility based on percent elongation. **Enter your answer to 1 decimal place e.g., 1.2**

**Figure Description:**
The main graph displays a stress-strain curve for the steel alloy specimen, with stress measured in megapascals (MPa) on the y-axis and strain on the x-axis. The curve starts steeply, indicating elastic deformation, before peaking and displaying a curve for plastic deformation.
- **Main Graph:**
- **X-Axis (Strain):** Range from 0.00 to 0.20.
- **Y-Axis (Stress in MPa):** Range from 0 to 600.
- The curve begins at (0,0), rises steeply to the highest point around 550 MPa at a strain of approximately 0.02, and then gradually declines indicating deformation until a strain of around 0.18.
- **Inset Graph:**
- A zoomed-in view of the initial portion of the stress-strain curve.
- **X-Axis (Strain):** Range from 0.000 to 0.006.
- **Y-Axis (Stress in MPa):** Range from 0 to 500.
- Highlights the linear elastic region of the graph.
