As we are going to start new topic i.e. shear force
and bending moment and therefore before going ahead let us see few basic
concepts of strength of material with the help of following links.

- Stress and strain in strength of materials
- Different types of stress
- Different types of strain
- Area moment of inertia
- The difference between centroid and centre of gravity
- Basic principle of complementary shear stresses
- Elongation of uniformly tapering circular rod
- Total elongation of the bar due to its own weight
- Thermal stress and strain
- Hook’s Law
- Derivation of relationship between young’s modulus of elasticity (E) and bulk modulus of elasticity (K)
- Elongation of uniformly tapering rectangular rod
- Basic principle of complementary shear stresses
- Volumetric strain of a rectangular body
- The perpendicular axis theorem and its proof
- The theorem of parallel axis about moment of inertia
- Moment of inertia for rectangular section
- Moment of inertia for the hollow rectangular section
- Moment of inertia for circular section
- Moment of inertia for the hollow circular section
- Method to determine the area moment of inertia for a hollow rectangular section, area moment of inertia for the rectangular section about a line passing through the base
- Concepts of mass moment of inertia
- Mass moment of inertia of a hollow rectangular section

Now we will see our current topic i.e. “Basic concepts of shear force and bending moment” in our next post.
