Crash Course Engineering

Stress, Strain & Quicksand

Today we’re talking all about fluid mechanics! We’ll look at different scales that we work with as engineers, mass and energy transfers, the no-slip condition, stress and strain, Newton’s law of viscosity, Reynold’s number, and more!

    Metals & Ceramics: Crash Course Engineering #19

    S1 E19 - 10m 3s

    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.

    S1 E18 - 11m 23s

    Today we’re going to start thinking about materials that are used in engineering. We’ll look at mechanical properties of materials, stress-strain diagrams, elasticity and toughness, and describe other material properties like hardness, creep strength, and fatigue strength.

    S1 E17 - 11m 16s

    Engineers use three processes to separate chemicals: distillation, which separates substances based on their different boiling points; liquid-liquid extraction, which uses differences in solubility to transfer a contaminant into a solvent; and reverse osmosis, which filters molecules from a solvent by pressurizing it through a semipermeable barrier.
