This course deals with the fundamental principle of solid mechanics. It also extends the fundamental concepts to three-dimensional continuos media. The relation of shear force and bending moment will be discussed. Shear force and bending moment diagram will also be introduced. The beam problem due to bending moment and shear force will be stated. The relationship between stress and strain will be studied. It also deals with Mohrs circle. Deflection of beam due to bending will be studied.
