The Bending Stress Calculator is a handy tool designed to help you determine the stress induced in a material due to a bending moment. This calculation is essential in engineering and construction to ensure that materials can withstand applied forces without failing.
Formula
The formula used for calculating bending stress is as follows:
- σ = M * y / I
Where:
- σ is the Bending Stress
- M is the Bending Moment
- y is the Distance from the Neutral Axis
- I is the Moment of Inertia
How to Use
Using the Bending Stress Calculator is straightforward:
- Enter the bending moment (M).
- Enter the distance from the neutral axis (y).
- Enter the moment of inertia (I).
- Click the “Calculate” button.
- The calculator will display the bending stress (σ).
Example
Suppose you have a bending moment of 500 Nm, a distance from the neutral axis of 0.05 m, and a moment of inertia of 0.001 m^4. You would enter:
- Bending Moment (M): 500
- Distance from Neutral Axis (y): 0.05
- Moment of Inertia (I): 0.001
The calculator will show a bending stress (σ) of approximately 25,000 N/m^2.
