MV2257 STRENGTH OF MATERIALS L T P C
3 0 0 3
AIM
To impart knowledge to the students about the Strength of Materials.
OBJECTIVES
To make the student learner, able to determine various stresses and strains in simple
and composite members under external load, strength of simple connections and strain
energy stored in members.
To make the student learner able to design beams which can resist bending and
shearing stresses and to teach the concept of principal stresses and maximum shear
stresses.
To teach the students to calculate the Shear force and Bending moment for the various
types of statically determinate and indeterminate beams and the method of drawing the
SFD and BMD.
To make the student learner able to calculate the deflections caused by the application
of loads and design of solid, hollow shafts, open coiled and closed coiled helical springs
based on shear and bending.
UNIT I 9
Concept of stress- tensile and compressive stresses- shear stress- Elastic limit –
Hooke’s law- Elastic constants and their relationship – Poisson’s ratio – Generalized
Hooke’s law – Elongation of Simple and composite bars under external load - allowable
stress – Factor of safety- Thermal stresses of Simple members – strength of simple
connections for cotter joints and screwed joints, Resilience-suddenly applied loads,
strain gauges.
UNIT II 9
Stresses in beams – neutral axis- theory of simple bending- bending stresses in
rectangular, I-sections and circular section beams. Bending stresses in composite
section beams. Shear stresses in beams –rectangular, I-sections and circular sections.
Stress components on a general plane and oblique plane - Principal stresses and
Principal Planes, Maximum shear stresses and their planes.
UNIT III 9
Bending moment-shear force, BMD and SFD for statically determinate beams-cantileversimply
supported--overhanging beams- with or without applied moments, point of contra
29
flexure. Statically indeterminate beams-BMD and SFD for fixed beams, propped
cantilever beams and continuous beams-theorem of three moments.
UNIT IV 9
Slope and deflection of Cantilever, overhanging and simply supported beams - Double
integration method - Moment area method- problems with various types of load with or
without applied moments and varying flexural rigidity (EI).
Torsion of solid and hollow circular shafts – power transmitted by shafts – compound
shafts - shafts subjected to both twisting and bending moment - Open coil and closed
coil helical springs.
UNIT V 9
Columns and struts - long and short columns- Euler’s formula for long column –
equivalent length – slenderness ratio - Eccentric loaded long and short columns -
Rankine Gordon formula, use of Strut formulae. Thin cylinders and thin spherical shellsunder
internal pressure-change in volume due to internal pressure. Thick cylinders –
simple treatment of thick cylindrical walled pressure vessels
TOTAL: 45 PERIODS
