Course Details

Mechanical engineering, in simple terms, deals with any equipment that moves; this is what makes it perhaps the broadest and most diverse engineering discipline. The mechanical discipline primarily derives its breadth from the need to design and manufacture everything from small (even nano) individual devices, such as measuring instruments, to large systems such as machine tools and power plants.

Easy installation and serviceability are critical to the success of a mechanical system, as is operational and design flexibility. Understanding parameters governing the selection and design of mechanical systems is essential for identifying suitable systems for a particular application.

To place all these issues in context, a good working knowledge of mechanical principles combined with a solid understanding of critical concepts such as force, energy, and heat is essential. Mechanical power transmission is discussed from the point of view of gears, couplings, and bearings. Proper selection and sizing of these critical mechanical components are vital to ensure optimum performance and improved efficiency of a mechanical system. Recently, fluid engineering has undergone significant change, and therefore, a detailed overview of the underlying principles of fluid power and its applications is vital. The theory behind heat transfer, the various heat transfer mechanisms, and the design of heat exchangers are also examined.

Any study of mechanical systems would be incomplete without including a review of mechanical vibrations. This will help you in monitoring, controlling, and analyzing vibrations and in conducting fault diagnoses in mechanical systems.

The field of maintenance has evolved into a separate and highly specialized function. An effective maintenance regime helps identify failure symptoms and enables the initiation of corrective measures for preventing unscheduled and sometimes catastrophic failures. Lastly, a discussion on the numerous standards, codes, and regulations governing mechanical systems helps put the whole course into perspective.

The course is composed of 12 modules, covering topics such as force, work, power, moments and torques, balanced and unbalanced forces and loads in a system, heat transfer mechanisms, gears and bearings, and the principles of design manufacturing.
