SA3301 Mechanics of Solids and Fluids Syllabus – Anna University Regulation 2021

OBJECTIVE

 At the end of this course the student is expected to have a knowledge of the concepts of Forces, Equilibrium, Stress, Strain, Shear force, Bending moment and torsion and should be able to apply these concepts to simple problems in beams and shafts. Further, he /she is also expected to gain knowledge of the fundamentals of fluid flow and their applications to flow through pipes and hydraulic machines. He / She should be able to solve application problems in these areas.

UNIT I DEFORMATION OF SOLIDS AND BENDING OF BEAMS

Concept of stress and strain – Normal and shear stresses – Simple and compound Stresses – Elasticity and elastic moduli – Poisson’s ratio – Concept of Shear Force and Bending Moment – Bending moment and shear force diagrams for simply supported, cantilever and over hanging beams.

UNIT II SHAFTS AND SPRINGS

Torsion – Shear stresses in circular solid and hollow shafts – Torque and power – Helical and leaf springs – Load, deflection, stress and stiffness relationships.

UNIT III FLUID PROPERTY AND FLOW CHARACTERISTICS

Surface tension – Capillarity – Viscosity – Newton’s law – Fluid pressure and pressure head – Fluid velocity – Uniform and steady flow – Reynolds number – Classification as laminar and turbulent flow – Continuity equation.

UNIT IV FLOW DYNAMICS AND MEASUREMENT IN PIPE NETWORKS

Euler’s and Bernoulli’s Equations – Manometer, Venturi meter and orifice meter – Pressure losses along the flow – Categorisation into minor losses – Flow through circular pipes – Statement of Darcy – Weisbach equation – Friction factor – Pipes in series and parallel – Hydraulic gradient.

UNIT V TURBINES AND PUMPS

Introduction and Classification of Turbines – Specific Speed – Turbine characteristics Speed Governance – Classification – Centrifugal Pumps – Impeller Blade Profiles – Cavitation in pumps – Pump characteristics – Efficiency – Reciprocating Pumps – Classification.

OUTCOMES:

On completion of the course, the student is expected to be able to
1. Understand how a solid (materials, structures) deforms when it is exposed to forces.
2. Apply the fundamental concepts of principle of superposition, equilibrium, compatibility, forcedeformation, and stress‐strain relationships to the solid and structural mechanics problems
3. Understand the properties and behaviour in static conditions. Also, to understand the conservation laws applicable to fluids and its application through fluid kinematics and dynamics
4. Explain the working principles of various turbines and design the various types of turbines.
5. Explain the working principles of centrifugal, reciprocating and rotary pumps and design the centrifugal and reciprocating pumps
