Question
**Question 5:** Based on the stress-strain diagram for a material shown here, find the following:

- Yield strength (MPa) =
- Ultimate strength (MPa) =
- Ductility (%) =
- Rupture strength (MPa) =

**Graph Explanation:**

The graph displayed is a stress-strain curve, which is a plot that shows the relationship between the stress applied to a material and the resulting strain (deformation).

- **Axes:**
  - The horizontal axis represents the strain with values ranging approximately from 0.00 to 0.24.
  - The vertical axis represents the stress in megapascals (MPa), ranging from 0 to 900 MPa.

- **Curve Details:**
  - The data is plotted in pink and represents the behavior of steel in an annealed state under stress.
  - Key points on the curve:
    - Initial linear region, indicating elastic behavior, followed by a yield point at approximately 738.56 MPa (0.01 strain).
    - The curve reaches a peak at around 497.31 MPa at 0.15 strain, indicating ultimate strength.
    - The material then undergoes strain hardening and necking until it reaches final rupture beyond the strain of 0.20.

- **Annotations:**
  - Markers on the graph indicate specific data points for stress at given strains.
  - The curve ends abruptly, showing the rupture point where the material fails. 

This graph can be used to determine yield strength, ultimate strength, ductility, and rupture strength, as requested in the question.
