The Flexural Strength of the Beam Depends upon

By Mohit Uniyal|Updated : July 22nd, 2022

The flexural strength of the beam depends upon____________

  1. Section Modulus of beam
  2. Bending Moment 
  3. Bending moment and Section Modulus of beam
  4. None of these 

Answer: C- Bending moment and section modulus of beam

The flexural strength of the beam depends upon the bending moment and section modulus of the beam.

Solution:

As defined by scientists, flexural strength is a material's resistance to breaking or fracture. Flexural strength reveals the amount of force needed to fracture a test sample with a certain measurement diameter. When this limit is reached, the test specimen cracks.

The flexural strength of the beam is given as

σb = M/Z

Where

  • b is the flexural strength of the beam
  • M is bending moment acting on the beam
  • Z is the section modulus of the beam.
