Course Objectives
- To introduce students how to apply the concepts of stress analysis, theories of failure and material science to model and analyze, design and/or select commonly used machine elements.
- To illustrate the variety of mechanical components available and emphasize the need to continue learning.
- To teach students how to apply mechanical engineering design theory to identify and quantify machine elements in the design of commonly used mechanical systems.
- To introduce how to apply computer based techniques in the modelling, analysis, design and/or selection of machine components.
Course Outcomes
The students will demonstrate the ability to apply the fundamentals of stress analysis, theories of failure and material science in the design of machine components. The students will also demonstrate the ability to make proper assumptions, perform correct analysis while drawing upon various mechanical engineering subject areas. Students will also demonstrate the ability to seek and learn new material in addition to the class topics through the completion of an open-ended project. <br /> <br />CO1: Knowledge will be gained on the subject matter <br />CO2: Ability to apply Knowledge of Engineering Graphics, Machine Drawing, Basic Science and Basic Applied Mathematics, Basic Machining Processes, Material Science, for design procedures of <br />Mechanical components use in Industries and incorporated in Machine Design. <br />CO3: Able to apply the theory to practical problems. <br />CO4: Knowledge will be enhanced to implement the concept for product development.
