Pressure Calculation
1. **State the problem:** We need to calculate the pressure on a brake pad given the force applied and the area of the brake pad.
2. **Write down the formula for pressure:**
$$\text{pressure} = \frac{\text{force}}{\text{area}}$$
3. **Identify the given values:**
- Force, $F = 140$ N
- Area, $A = 0.35$ m$^2$
4. **Substitute the values into the formula:**
$$\text{pressure} = \frac{140}{0.35}$$
5. **Calculate the pressure:**
$$\text{pressure} = 400 \text{ N/m}^2$$
6. **Interpret the result:** The pressure on the brake pad is 400 N/m$^2$, which means each square meter of the brake pad experiences a force of 400 Newtons.
