Force Formula:
From: | To: |
Definition: This calculator converts between pressure (psi) and force (pounds-force) using the contact area.
Purpose: It helps engineers and technicians determine the force generated by hydraulic/pneumatic systems or the pressure created by a given force.
The calculator uses the formula:
Where:
Explanation: Pressure multiplied by area equals force. This fundamental relationship is used in hydraulic systems, pneumatic systems, and mechanical design.
Details: Proper force calculation ensures correct sizing of hydraulic components, safety in pressure systems, and accurate mechanical designs.
Tips: Enter the pressure in psi and the area in square inches. Both values must be > 0.
Q1: What's the difference between psi and pounds of force?
A: PSI is pressure (force per unit area), while pounds of force is the total force applied over the entire area.
Q2: How do I find the area for circular surfaces?
A: Use \( A = \pi r^2 \) where r is radius in inches, or \( A = \pi d^2/4 \) where d is diameter in inches.
Q3: Can I use this for hydraulic cylinder force?
A: Yes, this is the standard calculation for hydraulic cylinder force based on system pressure and piston area.
Q4: What's a typical hydraulic system pressure?
A: Common hydraulic systems operate at 1500-3000 psi, but can range from 500 psi to over 10,000 psi.
Q5: How does this relate to torque?
A: Force can be converted to torque when applied at a distance from a pivot point (Torque = Force × Distance).
