Introduction to Strength of Material (SOM)-Mechanics of Deformable body

Strength of Material :-

It is study of internal resisting force developed due to elastic deformation of a body under the action of load.
Assumption made in Strength of Material Equation:-

1. Material is assumed to be homogeneous and isotropic.
2. Component is assumed to be prismatic.
3. Load is assumed as static load
4. Effect of self weight is neglected. 

Static Load:- 

When magnitude and direction is constant with respect to time.

Prismatic:-

All dimension are constant or same throughout the structure.

Homogeneous:-

Material is said it be isotropic, when it exhibit same elastic property at a point in a given direction.

Isotropic:-

Material is said it be isotropic, when it exhibit same elastic properties in any direction at a given point.
