Force Formula:
From: | To: |
Definition: This calculator converts pressure in pounds per square inch (PSI) to total force in pounds-force (lbf) based on the given area.
Purpose: It helps engineers, mechanics, and technicians determine the total force exerted by a given pressure over a specific area.
The calculator uses the formula:
Where:
Explanation: The pressure is multiplied by the area to calculate the total force exerted over that area.
Details: Accurate force calculations are essential for designing hydraulic systems, pneumatic systems, pressure vessels, and many mechanical applications.
Tips: Enter the pressure in psi and the area in square inches. All values must be > 0.
Q1: What is the difference between psi and lbf?
A: PSI (pounds per square inch) is a unit of pressure, while lbf (pounds-force) is a unit of force. PSI measures force per unit area.
Q2: Can I use this for hydraulic cylinder calculations?
A: Yes, this is commonly used to calculate the force output of hydraulic cylinders based on system pressure and piston area.
Q3: What's a typical application for this calculation?
A: Common applications include determining bolt clamping force, hydraulic cylinder force, or pressure vessel loading.
Q4: How do I find the area if I only know diameter?
A: For circular areas, use \( A = \pi \times r^2 \) where r is radius (diameter/2).
Q5: Does this account for friction or efficiency losses?
A: No, this calculates theoretical force. Actual force may be less due to friction and system inefficiencies.
