Types of Bending Stresses:
Bending stresses are those that bend the beam because of beam self-load and external load acting on it.
Bending stresses are of two types;
- Pure Bending
- Simple Bending
Pure Bending:
Bending will be called as pure bending when it occurs solely because of coupling on its end. In that case there is no chance of shear stress in the beam. But, the stress that will propagate in the beam as a result will be known as normal stress. Normal stress because it not causing any damages to beam. As shown below in the picture.
Simple Bending:
Bending will be called as simple bending when it occurs because of beam self-load and external load. This type of bending is also known as ordinary bending and in this type of bending results both shear stress and normal stress in the beam. As shown below in the figure.
