YOU THE MAN CARRIED ME THROUGH THIS 5 WEEK SUMMER CLASS! NOW YOU GOTTA GET ME THROUGH ELECTRICITY AND MAGNETISM FOR THE NEXT 6 WEEKS!
You are saving my life with this Statics course. Thank you for all the work that you put into this.
"The Newton-Hanson Laws" hahahah! Thanks for another great video Dr. Hanson :)
you are helping me to get this engineering degree. much respect to you, sir. and thank you very very much
Your explanations are awesome
you just untangled my confused mind thank you sir
ur lectures are really good , love the statics playlist , really good sir
i love you :)
I hate those who disliked this video. Mr. Hanson, thanks for the effort!!
Hi, your videos are great, I prepared structural mechanics exam watching your channel. Now I have mechanical behavior of materials and I still have some doubts with fatigue life estimation and calculation of max stress and strain using Neuber approach. Can you make some example about them? Thanks! Wish you all the best! 😉
Love your shirt Jeff, thanks for the lesson
Thank you always sir, long live!
Dr Hanson I stuck in new papa Guinea theory from three days 😂
Cant expresse my happiness when I solved first two problems first was cone and second is round ring
It looks soo easy at moment
How is this derived when compared to the conventional calculus approach for bodies of revolution?
haha i loved the part when u said "muy importante" nice pronuntation, excellent video !!
First of all thank you so much Jeff for the brilliant way you're teaching the course!
Can anybody tell me- is this theorem relates to Steiner theorem Mass moment of Inertia?
Because in our course we learnt Steiner's theorem but I'm not sure about pappus. Thanks!
Great teacher
what a boss whish he was my teacher
muchas gracias
in the fist figure should the y bar equal to 1.33?
No, the y bar is 1/3 from the side of the most area. This is why it's 1+2/3.
DR. Hanson thank you for explaining The Theorem of Pappus -Guldinus , Volume and Surface Area in mechanics. This theorem offer a simple way for computing the area of surfaces of revolution and the volume of bodies of revolution.
Shouldnt the y bar of first figure be 1.33
that was what i was tinking too
At time just after 8:37. How do we know that the height of triangle 1 and 3 are the same, meaning 1mm?
Triangle 1 is equal to 2mm-1mm=1mm. Triangle 3 is equal to 4mm-3mm=1mm.
Just wait till the semester starts then your videos will be flooded again lol
Hanson ,you are just awesome! But I have a "CONFUSION" that I think in the part of "S.A", section 4 will not be considered as that section 4 ,didn''t create any surfaces.
ah yes the NEWTON - HANSON laws, how could I forget :)
one shape in 4 quadrant two in first
Took me time
Forget x axis y axis
Start from bottom
X centroid is same
Y is 7 book want from axis one foot is above axis 6 foot is down ans is 1 foot from x axis 7 from bottom and x is same doesn't matter top or bottom
