One of the hardest concepts i've came across personally and you made it very understandable. Thank you so much Dr. Hanson

[CaptainJuiccy]

god i wish my proff was HALF as good as you are :( thankfully your videos are free, super helpful. thank you jeff!! i owe my degree to you

[LifeofFarhan]

You are a genius. Your videos will be helpful for generations and generations to come. Thank you Dr.Hanson

[cadeallen]

Perfect timing, we're doing this right now!

[INCRDIBLJMAN]

You're a life saver Dr/Prof Hanson

[cluccraft]

Very well explained. Intuitive and a lot easier this way. Thank you so so much for your work on education!
Much love from Brazil s2

Exceptional questions with Exceptional solution. You are at your best sir.

[leonidashadjiminas]

Wow. This is what engineering is about. If you can help someone visualize how physics works he will be able to understand any concept. Thank you, Sir.

[somshridhar]

I understood the concepts of rotation about, bending about, shear and normal force and torque application with how to estimate directions correctly. Thanks a lot professor 👌👌

[manuboker]

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

[dudeisorange]

I'm not in school anymore but this one sounds interesting!

[nilson]

thank youuuu... you might have just helped me pass!!!

[RobertArrington-fm]

Man, its too bad your a cowboys fan. lol Thanks for all of the help I don't know how i would do this without you!

[meowmeowmeow]

why is it done using the forces on the system rather than the reaction forces at the cross section?

[willfaulkner]

When you draw your graph, based on how you are looking at the piece. Should your positive x-axis be on the other side?

[mehmetdurdu]

ı follow u as liking from Turkey Dr. Hanson

[alvaroflores]

for the shear stress on point B isnt the force going to the negative direction? can someone clarify this part please

[VincentFrangipane]

When Jeff is calculating normal stresses, wouldnt one use (pi/4) * r^2? He just uses traditional pi r squared. In my class we use the pi over 4 and I've been clowned on for not using it.

[LLcoolJ-tvkd]

Why do you flip your x-axis, even thought you still have point A on the left side?

[kieranaxisa]

Can someone explain how and why sigma stress in the z direction zero, since there is a bending moment about the x-axis
