# STRENGTH OF MATERIALS

PRE-REQUISITE: Knowledge of Engineering mechanics.

Faculty: Dr. P.A.Krishnan

OBJECTIVE: To provide the same basic methodology to deformable bodies under the action of Forces and Torques.

1. Simple Stresses And Strains-Types of stresses-types of strain

2. Stress transformation equations. Principal stress and their planes. Plane of Maximum shear stress ÃƒÂ¯Ã‚Â¿Ã‚Â½ MohrÃƒÂ¯Ã‚Â¿Ã‚Â½s Circle for stress

3. Shear force and bending moment Diagrams for different types of beams like cantilever Relationship between loading - Shear force and bending moment diagrams for cantilever, simply supported and overhanging beams subjected to concentrated load and Uniformly Distributed Load(UDL)

4. Deflection equation elastic line of a beam ÃƒÂ¯Ã‚Â¿Ã‚Â½ Different methods to find deflection and slope of beams like MacaulyÃƒÂ¯Ã‚Â¿Ã‚Â½s method, moment area method and conjugate beam method.

5. Theory of simple torsion ÃƒÂ¯Ã‚Â¿Ã‚Â½ assumptions ÃƒÂ¯Ã‚Â¿Ã‚Â½ simple torsion formula for circular shafts ÃƒÂ¯Ã‚Â¿Ã‚Â½ hollow shafts ÃƒÂ¯Ã‚Â¿Ã‚Â½ power transmission ÃƒÂ¯Ã‚Â¿Ã‚Â½ strength and stiffness of shafts.
