1. What is Pressure?

Definition: Pressure is the amount of force applied perpendicular to the surface of an object per unit area.

Purpose: This calculator helps determine the pressure exerted when a force is applied over a specific area.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ P = \frac{F}{A} \]

Where:

Explanation: Pressure is calculated by dividing the applied force by the area over which the force is distributed.

3. Importance of Pressure Calculation

Details: Understanding pressure is crucial in engineering, physics, and many practical applications like hydraulic systems, structural design, and material science.

4. Using the Calculator

Tips: Enter the force in Newtons and area in square meters. Both values must be greater than zero.

5. Frequently Asked Questions (FAQ)

Q1: What are the units of pressure?
A: The SI unit is Pascal (Pa), which equals 1 Newton per square meter. Other common units include psi, bar, and atm.

Q2: How does area affect pressure?
A: For a constant force, pressure increases as area decreases (sharper objects exert more pressure).

Q3: What's a typical pressure example?
A: Atmospheric pressure at sea level is about 101,325 Pa (101.325 kPa).

Q4: Can I use different units?
A: Convert all values to SI units (N and m²) before calculation for accurate results in Pascals.

Q5: How is this different from stress?
A: Pressure is external force per area, while stress is internal resistance force per area within materials.
