DESIGN OF MACHINE ELEMENTS (MEE302) Proposed Syllabus MEE302 DESIGN OF MACHINE ELEMENTS 2 1 0 3Version No. 1.02 Prerequisite: MEE214 Strength of Materials Objectives: 1. To understand the design methodology for machine elements. 2. To analyze the forces acting on a machine element and apply the suitable design methodology. 3. To understand the various standards and methods of standardization. 4. To apply the concept of parametric design and validation by strength analysis. Expected Outcome: Student will be able to 1. Analyze and select machine elements/components. 2. Know the applications of the various elements, materials used to make them, and methods used 3. Integrate various machine elements and components into the design of a machine or mechanical system through a design project.
