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