M E Subjects – Mechanical Engineering Concepts Simplified

       Various topics of Mechanical Engineering presented are in a

        simple manner. It is based on our vast teaching experience.

         Anybody can make things complex. It is very difficult

         to make a topic simple.

         An attempt is there to make every article simple to read,

         understand and reproduce. Matter is from the literature

         available. Matter is in small sentences.

Strength of Materials
  • Simple stresses and strains
  • Principal stresses
  • Shear Force and Bending Moment Diagrams
  • Bending stresses in beams
  • Bending and axial loading combined
  • Slope and Deflection
  • Torsion
  • Columns and Struts
  • Strain energy
  • Thin shells
  • Thick shells
  • Springs
  • Stresses in curved beams
  • Shear Stresses in beams
  • Stresses in Rotating Discs
  • Theories of elastic failure
Heat Transfer
Temperature difference causes heat transfer. Modes of heat transfer
are conduction, convection and radiation. There are applications needing
reduction or increase in heat transfer.
  • Introduction
  • Conduction heat transfer
  • Convection heat transfer
  • Radiation heat transfer
  • Fins heat transfer
  • Heat exchangers
  • Dimensional analysis
  • Hydrodynamic and Thermal boundary layers
  • Boiling and Condensation
Refrigeration and Air Conditioning 
      It deals with refrigeration, comfort and industrial air conditioning.
      Refrigeration is lowering of temperature. It deals with preservation
      of life, taste and flavor. Comfort air conditioning increases human
      efficiency. Industrial air conditioning improves quality and quantity
      of products.
  • Vapor compression refrigeration
  • Gas refrigeration
  • Aircraft refrigeration
  • Vapor absorption Refrigeration
  • Expansion Valves
  • Refrigeration Equipment
  • Cooling loads
  • Psychrometry
  • Air Conditioning
  • Non- conventional refrigeration
  • Refrigerants
  Compressor converts electric energy into pressure and
thermal energy. Turbine converts thermal energy into
electric energy. Motor, pump, Mixi, engine, turbine are
thermodynamic devices.
  • Entropy
  • Boilers
  • Thermodynamic processes
  • Vapor Power  Cycles
  • Air standard cycles
  • Internal combustion Engines
  • Availability
  • Steam
  • Compressible flow
  • Nozzles
  • Jet Propulsion
  • Laws of Thermodynamics
Fluid Mechanics
It deals with different types of fluids and flows. It deals with
pressure drop and dimensional analysis.
  •  Dimensional Analysis,
  • Flow measurement
  • Laminar Flow,
  • Turbulent Flow,
  • Boundary Layer Theory
Theory of Machines
Deals with various types of motion, speed regulation,
power transmission and vibrations.
  • Degrees of freedom,
  • Power transmission Belts, Chains and Gears
  • Flywheel, Governor, Balancing
  • Degrees of freedom
  • Mechanical vibrations
Engineering Drawing
Deals with expressing ones ideas in a simple, quick and
convenient manner. Various types of projections help to
achieve the objective.
  •  Letter writing,
  • Dimensions,
  • Scales in drawing,
  • Projections of points, lines, planes and solids
  • Isometric and orthographic projections,
  • development of surfaces,
  • Section of solids
  • Intersection of surfaces
 Internal & external engines
 All types of vehicles use internal combustion engines.
External engines are boilers which feed high pressure steam
to turbines.
Different manufacturing processes produce various types
of objects.
