Professor Hanson, your students are very lucky having you as their professor. You make the difference, and one day, they will make the difference on future generations. Great attitude and approach, presenting not easy matter!

This is outstanding! Finally putting Mohrs circle and failure theories into two great examples of combined loading. Well done!!!

If you were my professor I would never skip class. I don’t skip class anyways, but at least I would be excited to come. 10/10 video as always. I wish nothing but good luck comes your way for the rest of your life. Lifesaver!!

Mandy is right for sure, thanks a lot!

Engine bolts when overheated will tend to do this, stretch beyond there recommended yield strength limit, most times you cannot see this as the necking of the bolt is not visible to the naked eye, many re-builders reuse the bolts without checking them with a simple bolt stretch gauge (test). Rod and head bolts are especially prone to this when the engine has been overheated. Excellent video series for students and us instructors to keep in practice, really useful as textbooks and samples materials are in short supply in Cambodia where I teach currently.

Imagines if Professor Henson teaches for fluid course 🥺

Great video, thank you Professor Hanson! I passed mechanics of materials and dynamics thanks to your help, and I’m now taking intermediate solid mechanics and advanced dynamics at UW Madison.

Wish my lectures where as passionate about their respective modules as you sir. Thanks for all the help!

[manuboker]

Wonderful solids lessons!! really taking the time to explain the problems along with a good sense of humor :))

Shouldn't the shear direction be the other way for example 2 on the stress element ?

[DONTfakeTOshow]

it is known that if the von Mises and Tresca criteria are assumed to agree for the case of uniaxial tension, then they will disagree for the case of pure shear and the von Mises yield circle will circumscribe the Tresca hexagon. SHOW that if it is assumed that the von Mises and Tresca criteria agree for the case of pure shear, then they will disagree for the case of uniaxial tension and the Tresca hexagon will circumscribe the von Mises ellipse)

You are amazinggg sir, but i have a question , when are u breaking bad ?

[aliihsankrka]

Sir, please continue to dynamics course. We need you.

So if my Tresca stress outputs a higher stress than Von Mises, does that mean that Tresca is saying for the same conditions, it's being more conservative?
