Bending Stress calculator

Bending stress is the stress developed in a beam due to bending moments. It is calculated based on the bending moment and the moment of inertia of the beam’s cross-sectional area. The formula for bending stress in a cantilever beam is given by:

where:

  • = Bending stress (in pascals, Pa or N/m²)
  • = Bending moment at the point of interest (in newton-meters, N·m)
  • = Distance from the neutral axis to the outermost fiber (in meters, m)
  • = Moment of inertia of the cross-sectional area (in meters to the fourth power, m⁴)
