Stress, Strain & Quicksand: Crash Course Engineering #12

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!

This looks so simple, but oh boy, when you go deep into it...

I feel like stress and strain need a few episodes each. This stuff is so, so important.

[losoggyspaghetti]

I'm starting my fall semester in 10 days and I'm taking fluid mechanics too. thank you so much I'm actually excited to learn about fluids now lol

[Anonymous-cvuh]

I’m taking fluid mechanics during the spring semester and I’m so pumped for it. Lol pun not intended.

Best CrashCourse ever... EVER!!!!
I love it...
I think it is easier to understand stress and strain in the context of beam theory. And then defined a fluid as a solid not able to carry stress in tension. But this works too...
I am looking forward to the FE and CFD videos it is going to be amassing.

In microfluidics, the flow is always laminar because the diameter is tiny (less than a millimeter), so when you pump in two different fluids, they don't mix easily. If you look up "microfluidic chip", you'll see that most of them have a zig-zag shape. That increases the length of the channel so the fluids can diffuse into each other and mix evenly along the way (although there are other reasons why you would want to make the channel longer).

You can either watch these videos for overview skim which actually makes your sch/uni/coll lesson easier or you have already learnt these at sch/uni/coll then come and watch for better understanding. Both actually worked. I have already tried with chemistry, physics, biology, anatomy and physiology.

I am taking Fluid Dynamics next Semester for my Engineering Studies. Thanks for the first insight, Shini & CC-Team :)

[laurenadegoke]

I'm taking biomedical transport phenomenon and it is basically fluid dynamics.. I can assure you all it is not fun. Thanks crash course for breaking this down for others.

[flamephlegm]

Normally I find the host speaks a little fast for me, but this ep was perfect. As always, full of great info.

[theodddodo]

Great video, thank you. Just a small point I think might need correcting: In the diagram accompanying the normal strain equation, I think the subscript of the total length (on the top) should be T for total. This would differentiate it from the shear strain LF.

[alexanderhoppe]

I learned more in this video than in half of my lectures on fluids mechanics

[mikey]

We did this in a level physics I love it :)

[holzdamolz]

CrashCourse, Are you able to make your content available on podcasts? I would love to listen to your videos while I work

[lazytv]

Ansys Fluent CFD is an interesting and helpful program for fluid mechanics/dynamics. Kind of wish they would talk about problems like cavitation or water hammer/hydraulic shock, unless that is in the next part...

[BrunosSquirrel]

OMG where were you this year when I failed my exam on rheology?!

[shayraviv]

Can you guys make a linguistics course?

[rakeshbam]

I had take the video 2x slower to make listening optimal since the delivery is very fluid.

[ximenaguevara]

I'd like to traslate these amazing series into Spanish since It's my mother tongue and I am really sure that some people around me or just that don't speak English would find them so helpful and interesting. Would it be possible drop the link here for that porpouse?

My first time watching— thank you, crash course, for giving a platform to a woman of color in STEM. You’re being the change we need in the world.
