This course comprises vast and detailed technical concepts on one of the oldest subject, Mechanical Engineering. It is one of the core engineering subjects that deals with the mechanisms of machines and machine elements. The subject is composed of the study of complete stages of machines including design, simulation, manufacturing, cost and wear calculation and so on. In order to master this subject, the learners should have an open mind to grasp all the concepts that dealing the machines. 
This course paves way for the learners to gain knowledge on the technical aspects and practical problems that illustrate the concepts of mechanical engineering subjects. It also has a cover up on basic concepts and terms used, technical drawings that are used for designing, common material properties and behaviors on load, failure mechanisms which are the limiting factors in any material design, Some design concepts on machine elements such as fasteners, rivets, gear drives and couplings have been discussed. The fundamental laws of thermodynamics and fluid mechanics provide the mass and energy transfer of working fluids. Details of various manufacturing processes like metal production and heat treatment, machines, their installation and maintenance have been included. 
The Students will learn the concepts of mechanical engineering, design of mechanical elements and role of mechanical engineers. This course is the right choice for those who have fundamental knowledge on mechanical engineering and are willing to learn detailed concepts and future technologies used.
