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!
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.
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!!
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.
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)
There's a symmetry to the shear stress. It will always be the opposite direction on the perpendicular face in order for the element to be in equilibrium.
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?

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

this man is simply the GOAT

Mandy is right for sure, thanks a lot!
Imagines if Professor Henson teaches for fluid course 🥺

Wish my lectures where as passionate about their respective modules as you sir. Thanks for all the help!
Thank you very much sir
YOU ARE SUPER COOL Professor
Wonderful solids lessons!! really taking the time to explain the problems along with a good sense of humor :))

You are amazinggg sir , but i have a question , when are u breaking bad ?
This dude is the GOAT
Amazing help, Thanks so much
Sir, please continue to dynamics course. We need you.
thank you. very good explaination
Shouldn't the shear direction be the other way for example 2 on the stress element ?
There's a symmetry to the shear stress. It will always be the opposite direction on the perpendicular face in order for the element to be in equilibrium.
you're absolutely right bud!
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?
Its more conservative he literally said it in the video bro
