The assumption “the plane section beforebending remains plane af...
Explanation:
Assumption in the theory of bending:
- The assumption that "the plane section before bending remains plane after bending" implies that the strain is uniform along the length of the beam.
Explanation:
- When a beam is subjected to bending, the top fibers of the beam are in compression while the bottom fibers are in tension.
- Due to this, the beam undergoes deformation, resulting in strain.
- The assumption that the plane section remains plane after bending means that the strain is the same throughout the length of the beam.
Implications:
- This assumption leads to the conclusion that the strain is uniform along the length of the beam.
- It does not necessarily imply that bending stress is the same at every section of the beam or that bending stress is proportional to strain at all sections.
- The assumption simply states that the deformation of the beam is consistent and uniform along its length.
Therefore, the correct implication of the assumption "the plane section before bending remains plane after bending" is that strain is uniform along the length of the beam.
