Calculating maximum bending stress in an I beam?

Click For Summary
SUMMARY

The maximum bending stress in an I-beam can be calculated using the flexural formula (σ/y) = (M/I), where σ represents bending stress, y is the distance from the neutral axis to the outermost fiber, M is the maximum bending moment, and I is the moment of inertia. To apply this formula, one must first determine the maximum bending moment acting on the beam. Additionally, knowledge of the I-beam's cross-sectional dimensions is essential for calculating the moment of inertia.

PREREQUISITES
  • Understanding of bending moment calculations
  • Familiarity with the flexural formula
  • Knowledge of moment of inertia concepts
  • Basic understanding of I-beam cross-sectional dimensions
NEXT STEPS
  • Research how to calculate the maximum bending moment for various loading conditions

Hello all, I am confused on how to calculate the maximum bending stress in an I-beam.

I found the maximum deflection in each beam where the load is placed at the center of the span.

I also know all the cross-sectional dimensions of the I-beam.

Is it now possible to calculate it?

Thanks

First of all, do you know the maximum bending moment on the beam? Do you know how to calculate bending stress?
 
Maximum Bending Stress can be found using flexural formula (σ/y)= (M/I) where σ is bending stress, y is distance of outermost fibre from the Neutra axis, M is maximum Bending moment and I is the Moment of Inertia.
