Stress Formula:
σ: Stress (Pascals, Pa)
F: Force (Newtons, N)
A: Area (square meters, m²)

Definition: This calculator determines the stress experienced by an object when a force is applied to a specific area.
Purpose: It helps engineers, physicists, and students analyze material strength and structural integrity under load.
The calculator uses the fundamental stress formula:
Where:
Explanation: Stress is calculated by dividing the applied force by the area over which the force is distributed.
Details: Proper stress analysis ensures materials aren't overloaded, preventing structural failures and ensuring safety in engineering applications.
Tips: Enter the force in Newtons and the area in square meters. Both values must be positive numbers.
Q1: What is a Pascal (Pa)?
A: One Pascal equals one Newton per square meter (N/m²). It's the SI unit for pressure and stress.
Q2: How do I convert other pressure units to Pascals?
A: 1 psi ≈ 6894.76 Pa, 1 bar = 100,000 Pa, 1 atm ≈ 101,325 Pa.
Q3: What's a typical stress value for common materials?
A: Steel can handle 250-400 MPa, aluminum 70-100 MPa, concrete 20-40 MPa in compression.
Q4: Does this calculate compressive or tensile stress?
A: The formula works for both - the nature depends on force direction (pushing or pulling).
Q5: How does area affect stress?
A: Larger area reduces stress (force is distributed), smaller area increases stress (force is concentrated).
