2 hours of brutal lecture, all summed up in an engaging way in 22 minutes. Thank you <3

You taught what my professor took a month to teach me. You are the most loved man at my school, everywhere in the engineering building students have your videos pulled up on your laptops.

Here's an chemical engineer student from the south of spain who learns a lot by you. I understand better mechanics of materials and now im ready to pass Material science subject. Cheers!!

You da man Jeff Hanson. Your videos are helping me through an Engineering degree which I used to think I wasn't smart enough to pursue. You're proof positive to the major impact a gifted educator can have on the life trajectory of the disenfranchised. Keep on keeping on Dr Hanson 🤙💪

This video is liquid gold. Thank you Jeff for everything!

Fantastic sir! I would like to add that I work in the Auto sector and we design the sheet metal components to be permanently deformed from their inception state of flat sheet metal so that they have the right functionality (toughness, shape etc)

[mtrik]

So amazing! I always thought of being a professor as a career, you are one of the few people that I look to and other professors should look up to aswell! Learning should be about understanding the material in ways that aren’t going to feel like chores, and you do that very well. Thanks so much for your content!

Jeff Hansen is an unsung hero to many mechanical engineering programs across the country / world

[danielzamora]

This guy literally explains it in a way that my professors thats so easy. My professors over complicate the subject.

[amitkandwal]

Hi Jeff, really great stuff. Thank you for sharing. A request, please post something on fatigue, fracture mechanics and mechanical vibration too.

Best tutoring video I've found online, complicated concepts were all explained in a understandable and fast way, thank you!

Fantastic Lecture! Regarding your question at 8:44 whether we design anything to be permanently deformed... Yes! Bike helmets are designed to get permanently deformed when they are actually used 🙂 The helmet deforms and takes the energy and prevents the force from getting transferred to the head. If the helmet did not deform, our heads would!

8:45 A dart board and and other similar targets, tears or holes to help open packaging

I think aluminum bolts in BMW's N52 engine are designed to permanently deform also because you must replace the bolts when they are removed. And after searching for this, I came across torque to yield fasteners (TTY) or stretch bolts.

M from India and i wish we had these kind of lectures in our classess, no extra drags just crisp of information and what an ossom clarity nothing that i should go back and google about. A best lecture,
Love from India❤❤❤

Such a great video! I have seen this question in books - Which is more elastic - steel or rubber? The general explanation is that materials with greater Young's modulus is more elastic. I don't understand this. It will be great if you could explain this better.

The break cartridges on one of those safety table saws that stops and retracts the blade when it senses a finger

[studocmatt]

I'm a dental student and this video helped me tremendously understand biomaterials, thank you Mr. Hanson!

[A.Hisham]

a whole semester on this topic, in 22min! Awesome.

[Adam_mohammed_]

Very helpful, I studied that in a course called (building materials) year ago. and I am studying it again in this course now (mechanics of materials)

[randompassbyer]

Nice lecture, my professor actually recommended us here ;)
