Very often both in academic life and Career life there needs the basic formulas of mechanical engineering as a mechanical scholar. There are included basic subject formulas. Very soon it will be published a enriched version including more subjects and with examples of mathematical problems. Now it contains basic six subjects like Thermodynamics, IC Engine, Theory of Machines, Fluid Mechanics, Heat and Mass Transfer, Strength of Materials, Power Plant Engineering and Refrigeration & Air Conditioning. When a scholar is going for a job test, he/she easily can be run over the formulas along with his/her journey. Its just a formula guide for mechanical engineers.
