Mechanical Systems of Engineering Complete

Mechanical Systems of Engineering / Basics of Mechanical Engineering / Elements of Mechanical Engineering is the subject designed for First year year Engineering students.  This is to enable all engineering students to get acquainted with the subject and also to get clear ideas of the mechanical devices / appliances which come across in real life. The course consists of Theoretical as well as numerical part.  Numericals are incorporated  as per syllabus structure so it is very beneficial for beginners  to get an idea about method / approach to solve the same. The data required for preparation of the subject takes more time as to search through various books and  web sites. The course hence designed with the requirement of the students so that they can save lot of time and also gain confidence to get through the subject with good score.

The course is divided into six units as below:

Unit-I :   Introduction to Energy sources and its Energy Conversions

Unit-II :  Introduction to Thermal Engineering

Unit-III : Introduction to Vehicles / Automobile Engineering and their Specifications

Unit-IV : Various Systems of Vehicle / Automobile

Unit-V :  Introduction to Manufacturing Processes

Unit-VI : Engineering Mechanisms and their application in Domestic appliances
