Question
In a tensile test for an aluminum alloy, the sample is 2 inches long and 0.5 inches in diameter. The proportional portion of the tension stress-strain diagram for an aluminum alloy is shown below.

Determine the axial stress of the sample under a tensile load of 9 kips: ____ ksi.

Pay attention to units and calculate your answer to 1 decimal place.

**Diagram Explanation:**

- The diagram is a graph illustrating the relationship between stress (\( \sigma \)) in ksi and strain (\( \varepsilon \)) in inches per inch.
- The graph shows a linear relationship, suggesting elastic behavior, with a slope representing the material’s modulus of elasticity.
- At a strain (\( \varepsilon \)) value of 0.00614 inches/inch, the stress (\( \sigma \)) reaches approximately 70 ksi. 
- An arrow indicates the direction of tensile load applied on a cylindrical sample.
