Stress and pressure are both forces per unit area. `T` in what respect does stress differ from Pressure?

Explanation

To understand the difference between stress and pressure, we can break it down into a step-by-step explanation:

### Step-by-Step Solution:

1. **Definition of Pressure**:
- Pressure is defined as the external force applied per unit area. It acts uniformly on the surface of an object and is always compressive in nature.
- Mathematically, pressure \( P \) can be expressed as:
\[
