UNIT II TRANSVERSE LOADING ON BEAMS AND STRESSES IN BEAM 12

Beams – types transverse loading on beams – Shear force and bending moment in beams – Cantilevers –
Simply supported beams and over hanging beams. Theory of simple bending– bending stress distribution –
Load carrying capacity – Proportioning of sections – Flitched beams – Shear stresses in beams – Shear flow.

UNIT III TORSION 12

Torsion formulation stresses and deformation in circular and hollows shafts – Stepped shafts– Deflection in
shafts fixed at the both ends – Stresses in helical springs – Maximum shear stress in spring section including
Wahl Factor - Deflection of helical springs, carriage springs.

UNIT IV DEFLECTION OF BEAMS AND COLUMNS 12
Double Integration method – Macaulay’s method – Area moment method for computation of slopes and
deflections in beams – Columns – End conditions – Equivalent length of a column – Euler equation –
Slenderness ratio – Rankine formula for columns.

UNIT V THIN CYLINDERS, SPHERES AND THICK CYLINDERS 12
Stresses in thin cylindrical shell due to internal pressure circumferential and longitudinal stresses and
deformation in thin and thick cylinders – spherical shells subjected to internal pressure –Deformation in
spherical shells – Lame’s theorem.
TOTAL: 60 PERIODS

OUTCOMES:
 Students can able to understand the different types of stress and strain in bars of varying cross section
and the need of Hooke’s law along with elastic constants and can understand the biaxial stresses.
 Students can understand the various types of beams subjected to various load conditions and will be
aware of shear force and bending moment diagram.
 Students can evaluate the torsion of various bars, shafts along with suitable power transmission and
can able select the suitable springs for the desired applications along with proper dimension.
 Students can understand the elastic curve of Neutral axis of the beam under normal loads and
evaluation of beam deflection and slope with various methods.
 Students can able to understand the construction of thin, thick cylindrical and spherical shells and
their application and can understand the Lame’s theorem.
