Experiment Time! Take out a paper clip, and consider how it was manufactured. Now, consider how, as a mechanical device undergoing cyclic strains, it will fail. How many times you could clip a single piece of paper before it failed? A stack of 20 sheets? A stack of 100? Or even bending it back and forth manually?
This is an example of the types of problems that guide our learning in ME371, where we together discover and implement engineering design and analysis concepts and tools regarding material failure modes, including yielding, fracture, and fatigue. We also consider specific elements as bolts, springs, rolling-element bearings, fluid-film lubrication, and power transmissions, including gears, friction drives, and clutches.
