Course Outcomes:
On completion of the course, the student will be able to:
- Explain stress and strain values and find the changes in axial, lateral and volumetric dimensions. Find thermal stresses in bodies of uniform section and composite sections. 1
- Solve the shear force and bending moment at any section of beam and draw the S.F. & B.M diagrams of UDL and Point loads.
- Show the deflection of beams, theory of columns and struts. 1
- Comparison of solid and hollow shafts, define and solve the stress and deflection of the closed coil helical spring. Illustratethe stresses on thin cylinders. 1
Module 1:
Simple Stresses and Strains: Types of forces (Tensile, Compressive and Shear); Stress, Strain and their nature; Mechanicalproperties of common engineering materials; Salient points on stress – strain diagram for ductile and brittle materials. Significance of factor of safety; Relation between elastic constants; Stress and strain values in bodies of uniform section and of composite section under the influence of normal forces; Thermal stresses in bodies of uniform section and composite sections; Simple numerical problems.

Module 3:
Theory of Simple Bending and Deflection of Beams: Explanation of terms: Neutral layer,Neutral Axis, Modulus of Section, Moment of Resistance, Bending stress, Radius of curvature; Assumptions in theory of simple bending; Bending Equation M/I = o/Y = E/R with derivation; Problems involving calculations of bending stress, modulus of section and moment of resistance; Calculation of safe loads and safe span and dimensions of crosssection; Definition and explanation of deflection as applied to beams; Deflection formulae without proof for cantilever and simply supported beams with point load and UDL only (Standard cases only); Simple numerical problems. Columns and struts Introduction – column- strut- buckling load- equivalent length- slenderness ratio – types of columns – short column- medium size column- long column – Euler’s equations and its assumption for crippling load for different end conditions (no proof) use of formulae – both end hinged -one end is fixed and other is free- one end is fixed and other is hinged- both ends fixed-equivalent length – Rankine’s formulae for columns – simple problems on columns to calculate buckling load- slenderness ratio- equivalent length on different end conditions.
Module 4:
Torsion in Shafts and Springs: Definition and function of shaft; Calculation of polar M.I. forsolid and hollow shafts; Assumptions in simple torsion; Derivation of the equation T/J=fs/R=G0/L; Problems on design of shaft based on strength and rigidity; comparison of strength and weight of solid and hollow shafts; Classification of springs; Nomenclature of closed coil helical spring; Deflection formula for closed coil helical spring (without derivation); stiffness of spring; Numerical problems on closed coil helical spring to find safe load, deflection, size of coil and number of coils. Thin Cylindrical Shells: Explanation of longitudinal and hoop stresses in the light of circumferential and longitudinal failure of shell; Expressions for the longitudinal and hoop stress; Simple numerical Problems for safe thickness and safe working pressure.
