Pressure Formula:
From: | To: |
Definition: This calculator computes pressure using the fundamental formula P = F/A, where pressure equals force divided by area.
Purpose: It helps students, engineers, and physicists calculate pressure in various applications from hydraulics to structural engineering.
The calculator uses the formula:
Where:
Explanation: Pressure is calculated by dividing the applied force by the contact area over which the force is distributed.
Details: Understanding pressure is crucial for designing structures, hydraulic systems, and understanding fluid dynamics in various engineering applications.
Tips: Enter the force in Newtons and area in square meters. Both values must be positive numbers.
Q1: What are the units of pressure?
A: The SI unit is Pascals (Pa), where 1 Pa = 1 N/m². Other common units include psi, bar, and atm.
Q2: How does area affect pressure?
A: Pressure is inversely proportional to area - smaller contact area means greater pressure for the same force.
Q3: What's a typical example of this principle?
A: Snowshoes distribute weight over larger area to reduce pressure and prevent sinking in snow.
Q4: Can I calculate force if I know pressure and area?
A: Yes, rearrange the formula: F = P × A.
Q5: What's the difference between pressure and stress?
A: Pressure is external force per area, while stress is internal resistance force per area within materials.
