Course on Design of Machine Elements

About Course

This course aims to develop the ability, to understand various elements involved in a mechanical system and use appropriate techniques, codes, standards and design principles for the design of mechanical systems.


Machine design is defined as the use of imagination, scientific principles and engineering process by which resources or energy is converted into useful mechanical forms, or the mechanisms to create a machine element, machine or system economically, in the desired form as per the needs so has to satisfy the requirements of customer.Machine design or Mechanical Design can lead to the formation of the entirely new machine element, product, machine, system or it can lead to improvement of the existing one.

Thus,Design engineers must have the knowledge of design principles, procedures and develop different ideas for new products and the systems. They should also be capable of modify the existing products or processes to increase efficiency or improve performance.Design process is an approach for breaking down a large project or process into manageable sub tasks or project or process to solve a variety of problems. Thus, design of various mechanical elements are important to design a components hence this course is designed gain an insight knowledge of various elements involved in a mechanical system and design them with attention to safety, reliability, societal and manufacturing aspects and then prepare professional quality solutions and presentations to effectively communicate the results of design and analysis.

What Will I Learn?

  • Understand the concepts of design principle sand the steps involved in the design process for a given mechanical components.
  • Apply design principles for the design of mechanical elements for relevant applications.
  • To design a mechanical system integrating machine elements.
  • To produce assembly and working drawings of various mechanical systems involving machine elements.
  • Apply engineering design tools to product design.
  • Become a good design engineers through learning the art of working in a team.
