Which of the following is/are an assumption(s) made in the theory of Simple Bending?

Explanation:

Following are the assumptions made in the theory of Simple Bending:

• The material of the beam is homogenous and isotropic.
• The beam is initially straight, and all the longitudinal fibres bend in circular arcs with a common centre of curvature.
• Members have symmetric cross-sections and are subjected to bending in the plane of symmetry.
• The beam is subjected to pure bending and the effect of shear is neglected.
• Plane sections through a beam, taken normal to the axis of the beam remain plane after the beam is subjected to bending.
• The radius of curvature is large as compared to the dimensions of the beam.
