### The main topics covered in the book

The book covers the following main topics:

Stress and strain: This topic introduces the concepts of stress and strain as measures of internal forces and deformations in a material due to external loads. It also explains the types of stress (normal, shear, bearing) and strain (linear, lateral, volumetric), as well as their relations (Hooke's law).

Elastic constants: This topic explains the concepts of elastic constants (modulus of elasticity, modulus of rigidity, bulk modulus) as measures of stiffness or resistance to deformation in a material. It also explains how to determine these constants experimentally or theoretically.

Thin cylinders and spheres: This topic deals with the analysis of thin cylindrical and spherical shells subjected to internal or external pressure. It explains how to calculate the hoop stress, longitudinal stress, volumetric strain, change in diameter and length in thin cylinders and spheres.

Principal stresses and strains: This topic deals with the analysis of complex stress systems where a material is subjected to more than one type or direction of stress. It explains how to find the principal stresses (maximum normal stress) and principal strains (maximum normal strain) using Mohr's circle or mathematical methods.

Strain energy and impact loading: This topic deals with the concept of strain energy as the work done by external forces in deforming a material elastically. It also explains how to calculate the strain energy due to axial load, shear load, bending load, torsion load, etc. It also deals with the concept of impact loading as a case where a material is subjected to a sudden or dynamic load. It explains how to calculate the impact load, impact stress, and impact factor.

Centre of gravity and moment of inertia: This topic deals with the concepts of centre of gravity and moment of inertia as measures of mass distribution in a body. It explains how to find the centre of gravity of a body using the principle of moments or integration methods.

It explains how to draw the shear force diagram and bending moment diagram for different types of beams (simply supported, overhanging, cantilever, etc.) and loading conditions (point load, uniformly distributed load, etc.). It also explains how to find the maximum shear force and bending moment in a beam.

Bending stresses in beams: This topic deals with the analysis of bending stresses in beams due to transverse loads.
