Force Equation:
| From: | To: |
The force equation F = P × A calculates the force exerted by a piston based on the pressure applied and the piston area. This fundamental physics equation is widely used in hydraulic systems, pneumatic systems, and mechanical engineering applications.
The calculator uses the force equation:
Where:
Explanation: The equation demonstrates that force is directly proportional to both pressure and area - increasing either pressure or area will result in greater force output.
Details: Accurate force calculation is essential for designing hydraulic systems, determining actuator capabilities, sizing mechanical components, and ensuring system safety and efficiency in various engineering applications.
Tips: Enter pressure in Pascals (Pa) and area in square meters (m²). Both values must be positive numbers greater than zero for accurate calculation.
Q1: What units should I use for pressure and area?
A: For consistent results, use Pascals (Pa) for pressure and square meters (m²) for area. The calculator will output force in Newtons (N).
Q2: Can I use different units with this calculator?
A: The calculator expects specific SI units. If you have measurements in different units (PSI, square inches, etc.), convert them to Pascals and square meters first.
Q3: What is the relationship between pressure, area and force?
A: Force equals pressure multiplied by area. This means that for a constant pressure, increasing the area will increase the force proportionally.
Q4: Where is this calculation commonly used?
A: This calculation is fundamental in hydraulic systems, pneumatic systems, press machines, braking systems, and any application where fluid pressure is converted to mechanical force.
Q5: What if I have a circular piston?
A: For circular pistons, calculate area using A = π × r² where r is the radius, then use that area value in the calculator.
