Concept explained with pictorial representation Utilization of multiple formulae for single process/operation. Techniques to solve high level problems. Practical implementation of formulae to be memorized. Extracted formulae from different chapters for candidates who don’t have basic knowledge of subjects. Subjects of relevance in competitive examinations and interviews have been discussed in each chapter. Important formulae and applications have been given in Tabular form for easy understanding. A Quick Glance on Technical Distinguished Features of the Book Engineering Mechanics: Given formulas for various conditions in Laws of Motion e.g. Force System-Most importantly Pictorial representation of concepts in Force System is given where as its usually in descriptive format. Formulas for determining Mass Moment of Inertia in different conditions is given in tabular form for simple shapes viz Sphere, Cylinder, and Rectangular block etc. Strength of Materials:MOHR circle for different loading conditions is given (See page no 55-59) which has a very high asking rate in competitiveexams esp. Gate and in interviews. Theory of Machines: Vibrations-Various conditions-Natural frequency formulae and Offset slider crank mechanism (refer page no.98) is given –again which is of very high importance in exams and interviews. Fluid Mechanics: Flow through pipes-different formulae has highlighted for various conditions viz. Head Loss, Discharge, Pressure difference has all been discussed. Thermodynamics: Heat and Work –We have various process viz: Constant Pressure, Volume, Temperature , Adiabatic, Polytrophic Process etc. for which there is standard formulas but in this book, we have given extracted formulas for the given conditions (see page no.297-301) Which shall surely help to 3-5 valuable seconds in competition level exams. HMT: Concept of radiation-Basic shape factor formulae for all geometries.
