Does this seem correct?

### Understanding Tensile Stress Tensile stress is an important concept in materials science and engineering. Here, we explore its definition through multiple-choice options: 1. **The same as force** - This option is incorrect. Tensile stress is not simply the force applied. 2. **Applied force per cross-sectional area** (✔️) - This option is correct. Tensile stress is the force applied to an object divided by the area over which the force is distributed, typically measured in Pascals (Pa). 3. **The strain per unit length** - This option is incorrect. Strain is a measure of deformation representing the displacement between particles in the material body. 4. **The ratio of the change in length** (✔️) - This option relates to strain rather than stress. However, in some contexts, the strain can indirectly indicate tensile properties. Understanding these distinctions is crucial for studying how materials respond to various forces, which is fundamental in designing safe and effective structures.
