Hands-On Method for Teaching Design of MechanicalComponents CourseHarold L. Stalford. School of Aerospace and Mechanical Engineering; University of Oklahoma, Norman,OK 73019; email: firstname.lastname@example.org Phone: (405) 325-1742AbstractA new hands-on method is presented for teaching a course on the design of mechanical components.Ref.  is an example of textbook used in our school’s course “Design of Mechanical Components”. Thiscourse requires the analysis and design of mechanical components such as fasteners, springs, bearings,gears, shafts, clutches, brakes, etc. Prerequisites include a course on solid mechanics or mechanics ofmaterials (e.g., Ref. ). Students coming into the course on Design of Mechanical Components areexpected to be fluent in performing free-body-diagrams, static equilibrium analysis, stress-strainanalysis, Mohr’s circle analysis, deflection analysis, etc. on structures with various loads (e.g., pointforces, moments, distributive loading) in axial, torsional, and bending configurations.On the first day of class, the students form teams of 5 to 6 students per team. Each team picks its choiceof a vehicle, machine or system from which they will pick all mechanical components for analysis anddesign in the course. Each team is required to carry out four (4) mechanical component projects and towrite a project report and make a presentation on each report. Each project covers a “3 to 4 weeks”time period. For example, fasteners and springs projects are “three-weeks” projects; bearings and gearsare “four-weeks” projects. Each team makes a presentation on each of the four project during thesemester. The presentations are judged by engineers from industry.The reports and presentations are required to cover analysis and design of team’s selected mechanicalcomponent from team’s same selected vehicle. The reports and presentations are required to covercomponent manufacturability and cost, environmental conditions, dimensions, loading conditions,design and statics treatment, stress-strain analysis, fatigue analysis, and simulation. On each project, ateam is required to select a team leader and to divide up the workload among all team members.The new hands-on method has been taught in 2012 and 2013; it has received high reviews fromstudents and industry judges alike.In this paper, we plan to describe all salient features of teaching a Design of Mechanical Componentscourse using the new hands-on method. Rubrics and grading criteria will be discussed.References  Robert C. Juvinall, Kurt M. Marshek, Fundamentals of Machine Component Design, Fifth Edition,John Wiley & Sons, Inc., 2012, Hoboken, NJ.
