Rationale
Specific shape and size of machine parts are required to be determined before we do the production of that machine or machine part. We have to also select specific material for that. This process of deciding shape, size and material is known as design. In designing a machine component it is necessary to have a good knowledge of many subjects such as Mathematics, Engineering Mechanics, Strength of Materials, Theory of Machines, Workshop Processes and Engineering Drawing. Students have learnt these subjects in previous semesters. The course curriculum provides the students knowledge of design process, as well as familiarity with design of components subjected to various stresses and moments like direct stress, bending stress, twisting moment and combined stresses. In this course students will learn design of components like cotter joint, knuckle joint, power screw, levers, helical and leaf springs, couplings, pressure vessels, bearings etc.
Course Outcome
The theory should be taught and practical should be carried out in such a manner that students are able to acquire required learning out comes in cognitive, psychomotor and affective domain to demonstrate following course outcomes.

i. Select the materials for the design of machine element
ii. Design simple machine elements subjected to direct stresses.
iii. Design simple machine elements subjected to bending stresses.
iv. Design machine elements subjected to direct and twisting moments.
v. Design machine elements subjected to direct and bending stresses.
