ME2254 STRENGTH OF MATERIALS SYLLABUS | ANNA UNIVERSITY BE MECHANICAL ENGINEERING 4TH SEM SYLLABUS REGULATION 2008 2011 2012-2013 BELOW IS THE ANNA UNIVERSITY FOURTH SEMESTER BE MECHANICAL ENGINEERING DEPARTMENT SYLLABUS, TEXTBOOKS, REFERENCE BOOKS,EXAM PORTIONS,QUESTION BANK,CLASS NOTES, IMPORTANT 2 MARKS, 8 MARKS, 16 MARKS TOPICS. IT IS APPLICABLE FOR ALL STUDENTS ADMITTED IN THE YEAR 2011 2012-2013 (ANNA UNIVERSITY CHENNAI,TRICHY,MADURAI,TIRUNELVELI,COIMBATORE), 2008 REGULATION OF ANNA UNIVERSITY CHENNAI AND STUDENTS ADMITTED IN ANNA UNIVERSITY CHENNAI DURING 2009
ME2254 STRENGTH OF MATERIALS L T P C
(Common to Mechanical, Automobile & Production) 3 1 0 4
OBJECTIVES
To gain knowledge of simple stresses, strains and deformation in components due to
external loads.
To assess stresses and deformations through mathematical models of beams,
twisting bars or combinations of both.
Effect of component dimensions and shape on stresses and deformations are to be
understood.
The study would provide knowledge for use in the design courses
UNIT I STRESS STRAIN DEFORMATION OF SOLIDS 12
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.
36
UNIT II BEAMS - LOADS AND STRESSES 12
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 12
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 BEAM DEFLECTION 12
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 12
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.
