Love the Just a Moment Joke! ahaha
Loved the moment pun! Thank you
That just a moment joke would have been perfect if there was an ad at that moment
These videos have been more useful to me in 30 minutes than a week of lectures. You are the best.

thank you Doctor Hanson, you are a legend
You're the best sir!
Thanks for the videos :)
you are awesome its so useful thanks
Thank you for your valuable information @Mr. Jeff Hanson! Hello everyone, I have a question about that, If we apply heat treatment to related shaft, will there be any improvement regarding the angle of twist or shaft safety? I mean, How can we calculate the effects of heat treatment in case of comparing the case hardened steel or induction hardened steel (20MnCr5 vs 4140)during calculation of torsion on the shaft?
Wonderful solids lessons!! really taking the time to explain the problems along with a good sense of humor :))
RESPECT!!
so for the counterclockwise 8 kn-m.. if I were to block the left side of the cut, wouldnt it be going clockwise as theres only the 8 kn-m there?
best teacher
so if we have hollow shaft and wanna know what is the shear stress at inside diameter which is Ri. Which J that we gonna use. I think we consider it like solidshaft and use the first one.
Nice
Professor, what if the element is a hollow disk? What is the formula we can use to calculate the torsional stress?
Last minutes safe a man

can someone please explain to me why he used C= 20mm as his furthest point of intersection? Shouldnt it be C = 40mm?

that is the outside diameter not the radius
Is it a procedure? I am not having alot of fun as I was in statics 🤔
Dr. Hanson, shouldn't CD be 7kN*m and not 8kN*m? 15-8=7

Can someone explain to me why he used MPa as the units for the final answer?

A bit late but the standard unit for pressure is the pascal (N/m^2), but since he did his calculations using mm, his final answer would have been in N/mm^2, which is the megapascal
Hi, can someone help me determining the torque at the End-B of a shaft that is 40ft long and with an applied torque on one end-A of 30,000 ft-lb.
You didn't treat internal forces on suspended frame
❤❤❤❤❤
Sir you look to me mummy return character in 2018 look same
LOL 3:40
might be a stupid question but why is it 20mm for C
@tonicakarun1731

Prolly too late but it's half of the outer diameter as we want to find the biggest shear stress(which is located at the further most point from the rotation center)

@@tonicakarun1731 isnt it suppose to be 40mm because it is from the centre of the circle no?

@@damhilmnNo, 40mm is the diameter. We need radius so 40 ÷ 2 = 20mm.

sorry but I'm confused why you used c= 20mm ? would appreciate if anyone can explain it to me. thank you...

Hello, not sure how correct I am on this, but since c is measured from the center of the shaft to the point of interest (which in this case is the outer part of the shaft) then c pretty much acts like the outer radius of the shaft which is 40mm/2 = 20mm. Hope this helped.
