Mechanical engineering is one of the primitive and diversified domains revolving around the core implementation of subjects like physics and mathematics. Though this branch of engineering seems physical to a greater extent, but thermal engineering converges to a crucial segment into the domain. In the aspects of design and production analysis of systems, the influence of thermal engineering parameters is also significant. Out of several major influential subjects, this book specially insists upon the subjects like engineering mechanics, thermodynamics, materials science, heat transfer, refrigeration and air conditioning, internal combustion engine and gas turbines, and power plant engineering. This book supports module wise objective class of questions and their answers. Apart from this, the book showcases the specific explanations to the answers.
