• Analysis for Mechanical Design – Adv. Solid Mechanics topics, Fatigue, Fracture, Analysis for displacement & strength, CosmosWorks (FEA), “failure analysis” of components
• Mechanical Engineering Design – Components: Bearings, Gears, Cams & Mechanisms, Bolts, Belts, Shafts, etc. Project work in teams w/ machining. Written reports & presentations required. Often involves a class competition.
• Mechanical Systems Design – Design, Analysis & Testing of an entire system to meet a “client’s needs.” Team-work, machining, realistic constraints, etc.
“CDIO” Course Descriptions
Engineering Innovation Examples
Above: Save the Astronauts (Eggs). Device needed to rescue without killing the astronauts. It “landed” on one table & astronauts were on other table. Device could only be powered by potential energy & started with the cutting of a string. Extra points gained from lighting LED’s using magnetic sensors.
Right: Chain Reaction Design Challenge. 4 sub-groups design a separate component which is started by the previous one and ends by starting the next. Must have action & a common theme.
Mechanical Engineering Design Examples
“Mrs. Smith’s Apple Pie Helper”
Using an Apple Slicer – Design a “machine” to slice the apple, remove the core & transport apple slices 1 foot away into a dish for apple pie. Can only use rotary mechanical motion to power the device.
“Skeeball” Competition
Design a machine, powered by a cordless screwdriver to throw/launch plastic air-filled balls at a target 6 feet away. Pts for accuracy & quantity.
Solar Energy used to charge bank of batteries for back-up power during a blackout .. Design of cabinet + system electronics, etc. … testing, stress analysis…
“Sustainable Neighborhood Vehicle” –Interdisciplinary Team
Solar Energy to power the vehicle
