Question

What is the purpose of an internal moment in a section?

1) To generate a bending moment
2) To maintain equilibrium
3) To create a force couple
4) To oppose the bending moment

Answer 1

The purpose of an internal moment in a section is to oppose the bending moment. When a beam or any structural section is subjected to a bending moment, it experiences internal forces called internal moments to resist the bending moment and prevent excessive deformation or failure.

Step-by-step explanation:

The purpose of an internal moment in a section is to oppose the bending moment.

When a beam or any structural section is subjected to a bending moment, it experiences internal forces called internal moments. These internal moments develop within the section to resist the bending moment and prevent the section from undergoing excessive deformation or failure.
