Bending moment for curve and straight beam

Click For Summary
SUMMARY

The bending moment for a curved beam is consistently less than that of a straight beam due to the relationship between bending stress and moment of inertia. While the bending moment is influenced by the applied load and distance, it remains independent of the moment of inertia. In contrast, bending stress is directly affected by the moment of inertia, leading to different behaviors in curved versus straight beams.

PREREQUISITES
  • Understanding of bending moment and bending stress concepts
  • Familiarity with moment of inertia calculations
  • Knowledge of beam theory and mechanics of materials
  • Basic principles of structural engineering
NEXT STEPS
  • Research the relationship between bending moment and load distribution in beams
  • Study the calculations for moment of inertia in various beam shapes
  • Explore the differences in bending stress for curved versus straight beams
  • Learn about beam deflection and its implications in structural design
USEFUL FOR

Structural engineers, civil engineering students, and professionals involved in beam design and analysis will benefit from this discussion.

It’s clear that bending moment for a curve beam is less than straight one
And you can attribute this to moment of inertia, but there is something i don’t understand
Which is if i have straight beam with small moment of inertia or huge moment of inertia simple supported beam), the moment will not differ, so why it will differ in curve beam.

some help please
 
Are you confusing bending stress with bending moment? Bending moment is a function of load and distance and has nothing to do with moment of inertia. Bending stress is dependent on the moment of inertia.
