**ME2254 STRENGTH OF MATERIALS**

** (Common to Mechanical, Automobile & Production)**

** UNIT I STRESS STRAIN DEFORMATION OF SOLIDS**

Rigid and Deformable bodies – Strength, Stiffness and Stability – Stresses; Tensile,

Compressive and Shear – Deformation of simple and compound bars under axial load –

Thermal stress – Elastic constants – Strain energy and unit strain energy – Strain energy

in uniaxial loads.

** UNIT II BEAMS – LOADS AND STRESSES**

Types of beams: Supports and Loads – Shear force and Bending Moment in beams –

Cantilever, Simply supported and Overhanging beams – Stresses in beams – Theory of

simple bending – Stress variation along the length and in the beam section – Effect of

shape of beam section on stress induced – Shear stresses in beams – Shear flow

** UNIT III TORSION**

Analysis of torsion of circular bars – Shear stress distribution – Bars of Solid and hollow

circular section – Stepped shaft – Twist and torsion stiffness – Compound shafts – Fixed

and simply supported shafts – Application to close-coiled helical springs – Maximum

shear stress in spring section including Wahl Factor – Deflection of helical coil springs

under axial loads – Design of helical coil springs – stresses in helical coil springs under

torsion loads

** UNIT IV BEAMDEFLECTION**

Elastic curve of Neutral axis of the beam under normal loads – Evaluation of beam

deflection and slope: Double integration method, Macaulay Method, and Moment-area

Method –Columns – End conditions – Equivalent length of a column – Euler equation –

Slenderness ratio – Rankine formula for columns

** UNIT V ANALYSIS OF STRESSES IN TWO DIMENSIONS**

Biaxial state of stresses – Thin cylindrical and spherical shells – Deformation in thin

cylindrical and spherical shells – Biaxial stresses at a point – Stresses on inclined plane

– Principal planes and stresses – Mohr’s circle for biaxial stresses – Maximum shear

stress – Strain energy in bending and torsion.
