 Course Objectives and Outcomes

• Learn the design process of mechanical components such as screws, fasteners for different design considerations, such like strength, stiffness, and stability under steady and variable loading.
• Transfer real life machine elements such as bearings to analytical models and analyze them as well as to deal with design codes and standards.
• To solve open-ended design problems, cope with decision making and satisfy competing objectives.
• Use and integrate the fundamentals studied previously towards the goal of analyzing and designing mechanical components such as gears to achieve satisfactory design.
• Use appropriate software for design, modeling, and analysis. To incorporate knowledge learned in the mechanics, structures, materials, and manufacturing courses.
• To learn the design of brakes, clutches and mechanical springs for various types of machines.
• To design and select belts and pulleys by specifying their type, geometry, material, life, and safety and how to integrate different fields of mechanical engineering to build a mechanical system.
• Work in teams to complete the given design tasks in multidisciplinary areas of engineering and communicate the designs effectively.
