CrashCourse

Today we’ll explore more about two of the three main types of materials that we use as engineers: metals and ceramics. We’ll discuss properties of metals, alloys, ceramics, clay, cement, and glass-ceramic materials. We’ll also look at the applications of our materials with microelectromechanical systems and accelerometers.

Correction: aluminum oxide is not rust; rust refers only to iron oxide. Aluminum does corrode and the process by which it corrodes has been referred to as 'rusting', even if it is technically not rusting unless the material is iron or steel.

Crash Course Engineering is produced in association with PBS Digital Studios: https://www.youtube.com/playlist?list=PL1mtdjDVOoOqJzeaJAV15Tq0tZ1vKj7ZV
