CE8402 Strength of Materials II Previous Year Question Paper For Regulation 2017


OBJECTIVES:
 To know the method of finding slope and deflection of beams and trusses using energy
theorems and to know the concept of analysing indeterminate beam
 To estimate the load carrying capacity of columns, stresses due to unsymmetrical bending
and various theories for failure of materials

UNIT I ENERGY PRINCIPLES 
Strain energy and strain energy density – strain energy due to axial load (gradual, sudden and
impact loadings) , shear, flexure and torsion – Castigliano’s theorems – Maxwell’s reciprocal
theorem – Principle of virtual work – unit load method – Application of energy theorems for
computing deflections in determinate beams , plane frames and plane trusses – lack of fit and
temperature effects – Williot Mohr’s Diagram.

UNIT II INDETERMINATE BEAMS 
Concept of Analysis – Propped cantilever and fixed beams – fixed end moments and reactions –
sinking and rotation of supports – Theorem of three moments – analysis of continuous beams –
shear force and bending moment diagrams.

UNIT III COLUMNS AND CYLINDERS 
Euler’s column theory – critical load for prismatic columns with different end conditions – Effective
length – limitations – Rankine-Gordon formula – Eccentrically loaded columns – middle third rule –
core of a section – Thin cylindrical and spherical shells – stresses and change in dimensions –
Thick cylinders – Compound cylinders – shrinking on stresses.

UNIT IV STATE OF STRESS IN THREE DIMENSIONS 
Stress tensor at a point – Stress invariants – Determination of principal stresses and principal
planes – Volumetric strain. Theories of failure: Maximum Principal stress theory – Maximum
Principal strain theory – Maximum shear stress theory – Total Strain energy theory – Maximum
distortion energy theory – Application problems.

UNIT V ADVANCED TOPICS 
Unsymmetrical bending of beams of symmetrical and unsymmetrical sections – Shear Centre –
curved beams – Winkler Bach formula – stresses in hooks.

OUTCOMES:
Students will be able to
 Determine the strain energy and compute the deflection of determinate beams, frames and
trusses using energy principles.
 Analyze propped cantilever, fixed beams and continuous beams using theorem of three
moment equation for external loadings and support settlements.
 find the load carrying capacity of columns and stresses induced in columns and cylinders
 Determine principal stresses and planes for an element in three dimensional state of stress
and study various theories of failure
 Determine the stresses due to Unsymmetrical bending of beams, locate the shear center,
and find the stresses in curved beams.
