CE2201 MECHANICS OF SOLIDS
OBJECTIVE
The subject of Mechanics of Solids cuts broadly across all branches of engineering profession. At the end of this course, the student will have knowledge about behaviour of members subjected to various type of forces. The subject can be mastered best by solving numerous problems.
UNIT I STRESS STRAIN AND DEFORMATION OF SOLIDS, STATES OF STRESS
Rigid bodies and deformable solids – stability, strength, stiffness – tension, compression and shear stresses – strain, elasticity, Hooke’s law, limit of proportionately, modules of elasticity, stress-strain curve, lateral strain – temperature stresses – deformation of simple and compound bars – shear modulus, bulk modulus, relationship between elastic constants – biaxial state of stress – stress at a point – stress on inclined plane – principal stresses and principal planes – Mohr’s circle of stresses.
UNIT II ANALYSIS OF PLANE TRUSS, THIN CYLINDERS / SHELLS
Stability and equilibrium of plane frames – types of trusses – analysis of forces in trussmembers method of joints, method of sections, method of tension coefficients – thin cylinders and shells – under internal pressure – deformation of thin cylinders and shells.
UNIT III TRANSVERSE LOADING ON BEAMS
Beams – types of supports – simple and fixed, types of load – concentrated, uniformly distributed, varying distributed load, combination of above loading – relationship between bending moment and shear force – bending moment, shear force diagram for simply supported, cantilever and over hanging beams – Theory of simple bending – analysis of stresses – load carrying capacity of beams – proportioning of sections
UNIT IV DEFLECTION OF BEAMS AND SHEAR STRESSES
Deflection of beams – double integration method – Macaulay’s method – slope and deflection using moment area method, Conjugate Beam method – variation of shear stress – shear stress distribution in rectangular, I sections, solid circular sections, hollow circular sections, angle and channel sections – shear flow – shear centre.
UNIT V TORSION AND SPRINGS
Stresses and deformation in circular (solid and hollow shafts) – stepped shafts – shafts fixed at both ends – leaf springs – stresses in helical springs – deflection of springs.
