railway RRB JE (CBT I + CBT II) Mock Test 2024 Strength of Materials Shear Stress and Bending Stress
Which of the following is not an assumption in the Theory of Simple Bending?
1
The material of the beam is homogenous and isotropic
2
The beam is initially straight, and all the longitudinal fibres bend in circular arcs with a common centre of curvature
3
The radius of curvature is small as compared to the dimensions of the beam
4
The beam is subjected to pure bending and the effect of shear is neglected
