.
Note:
Design Data books are not permitted in the Examinations. The design must not only satisfy strength criteria but also rigidity criteria.
Course Objectives:
- To understand the general design procedures and principles in the design of machine elements.
- To study different materials of construction and their properties and factors determining the selection of material for various applications.
- To determine stresses under different loading conditions.
- To learn the design procedure of different fasteners, joints, shafts and couplings.
