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!
jeff: "What is a failure" me looking at the mirror*
Imagines if Professor Henson teaches for fluid course 🥺
Mandy is right for sure, thanks a lot!
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!!
This is outstanding! Finally putting Mohrs circle and failure theories into two great examples of combined loading. Well done!!!
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.
Wonderful solids lessons!! really taking the time to explain the problems along with a good sense of humor :))
Wish my lectures where as passionate about their respective modules as you sir. Thanks for all the help!
thank you. very good explaination
Amazing help, Thanks so much
This dude is the GOAT
Sir, please continue to dynamics course. We need you.
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?
You are amazinggg sir , but i have a question , when are u breaking bad ?
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)
