A rod has a radius of 100 mm and a length of 10 cm. A 100 N force compresses along its length . Calculate the longitudinal stress developed in the rod.

Explanation

To calculate the longitudinal stress developed in the rod, we will follow these steps:

### Step 1: Convert the given dimensions into SI units
- The radius of the rod is given as 100 mm.
\[ \text{Radius} = 100 \text{ mm} = 100 \times 10^{-3} \text{ m} = 0.1 \text{ m} \]
- The length of the rod is given as 10 cm.
