Question

1. Does the beam section designed on Maximum shear force value criteria differ the
section designed on maximum bending moment criteria? Justify your answer.
​

Answer 1

Answer:

A beam of rectangular cross-section is subjected to a bending moment M (N·m) and a maximum shear force V (N). The bending stress in the beam is calculated as σ = 6M/bd2 (Pa), and average shear stress is calculated as τ = 3V/2bd (Pa), where b is the width and d is the depth of the beam.
