OBJECTIVE:
Enable the student to understand the behaviour of deformable
structural elements, subjected
to different types of loadings
UNIT I STRESS, STRAIN AND
DEFORMATION OF SOLIDS 12
Rigid and deformable bodies – Stability, strength and stiffness
- Axial and Shear Stresses –
Deformation of simple and compound bars –
Thermal stresses – Biaxial state of stress –
Elastic Constants - Stresses and deformation of thin cylindrical
and spherical shells –
Stresses at a point –
Stress tensor - Stresses on inclined
planes – Principal stresses and
principal planes – Mohr’s circle of stress.
UNIT II ANALYSIS OF PLANE
TRUSSES
12
Stability and equilibrium of plane frames –
perfect frames - types of trusses – Analysis of
forces in truss members –
Method of joints – Method of tension
co-efficient – Method of
sections.
UNIT III BENDING OF
BEAMS
12
Beams – types and transverse loading on beams –
shear force and bending moment in
beams – Cantilever beams – Simply supported beams and over-hanging
beams - Theory of
simple bending – bending stress distribution – Load
carrying capacity – Proportioning of
sections – Leaf springs – Flitched beams – Shear stress
distribution.
UNIT IV TORSION
12
Theory of simple torsion -
Stresses and deformation in circular and hollow shafts – Stepped
shafts – Shafts fixed at both ends – Stresses and deflection in
helical springs.
UNIT V DEFLECTION OF
BEAMS
12
Double Integration method – Macaulay’s method – Area moment method
– Conjugate beam
method for computation of slopes and deflections in determinate
beams.
