- Click ‘Calculate’.
- View your results and chart below.
Formula & Methodology
The formula for beam shear stress (τ) is:
τ = F / (b * h)
Where:
- F is the force applied to the beam,
- b is the width of the beam, and
- h is the height of the beam.
Real-World Examples
Case 1: Steel Beam
F = 100,000 N, b = 0.2 m, h = 0.5 m
τ = 100,000 / (0.2 * 0.5) = 1,000,000 Pa
Case 2: Concrete Beam
F = 200,000 N, b = 0.3 m, h = 0.6 m
τ = 200,000 / (0.3 * 0.6) = 1,111,111 Pa
Case 3: Wood Beam
F = 50,000 N, b = 0.15 m, h = 0.3 m
τ = 50,000 / (0.15 * 0.3) = 1,166,667 Pa

Interactive FAQ
What is beam shear stress?
Beam shear stress is the stress experienced by a beam due to the applied force, calculated as the force divided by the product of the beam’s width and height.
How do I interpret the results?
Compare your calculated shear stress to the material’s shear strength to ensure your beam is safe and reliable.
