Stress Formula:
Where:
σ: Stress (Pa)
F: Force (N)
A: Area (m²)
From: | To: |
Definition: This calculator determines the stress (σ) on a material by dividing the applied force by the cross-sectional area.
Purpose: It helps engineers and students analyze material strength and structural integrity under various loads.
The calculator uses the formula:
Where:
Explanation: Stress is calculated as the force distributed over the area it acts upon.
Details: Proper stress analysis ensures materials won't fail under load, helps in material selection, and is fundamental in structural design.
Tips: Enter the force in Newtons and the cross-sectional area in square meters. All values must be > 0.
Q1: What's the difference between stress and pressure?
A: Stress is internal resistance to deformation, while pressure is external force per unit area.
Q2: What are typical stress values for common materials?
A: Steel ~250 MPa, Aluminum ~70 MPa, Concrete ~20-40 MPa in compression.
Q3: How do I convert between Pascals and other units?
A: 1 MPa = 1,000,000 Pa, 1 GPa = 1,000 MPa.
Q4: What if my area isn't in square meters?
A: Convert to m² first (1 m² = 10,000 cm² = 1,000,000 mm²).
Q5: Does this calculate tensile or compressive stress?
A: The same formula works for both - the sign indicates direction (tension +, compression -).
