6 weeks left in the semester, 8 assignments a week and 3 midterms. This guy is saving my behind right now.

[@terrancepage9163]

I learned more in the first 5 mins of this video than in my entire chapter in the textbook. The textbook went on and on and on about the derivation of the equations and didn't give me any intuition into what I was looking at. Dr. Hanson is an absolute legend!!

[@aieman8607]

Bro really change destiny of many who watch his video..some who should repeat a year pass, same want to pass got good grade ...thank you so much❤❤

[@wadeanderson2984]

I have an exam on this stuff in 3 weeks. Seeing this is one day ago is insane. LETS GO!

[@rastyisanerd3686]

Simple and straightforward, thank you once again Mr.Hanson.

[@-thesignpainter9486]

your pfp is very fitting for an engineering student 😭

[@thomazzz02yt84]

Love the videos actually got this subject today during the lecture so right on time!

14 hours before end sem ...... This guy saving me big time

[@quakershaker7475]

thank you for these videos extremely helpful. im using a shigleys mechanical engineering design manual and the book uses the same equation for stress prime y as x but at a different angle which could be easily interpreted wrong. your method is a simpler and more reliable, well for me anyway.

[@Shampoo2004]

Thank you so much mister, solids has been so hard and yes you helped reduce A LOT of my stress 😂

[@manuboker1]

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

[@andrepoiy1199]

My prof said specifically that these equations are not on the exam, but if you could memorize them you'd get full marks on the question....

[@hamcheez7490]

skipped 2 wk of lectures, jeff is actually coming in clutch atm

[@ebenezerocran]

That is a beautiful start right there 😊

[@jesseyniiarmah5486]

thank you very much mr jeff hanson

[@eduardomoreira7624]

The answer at the end is incorrect . He wrote 25 when it was 125 and the final answer should’ve been in tension 70.75MPa

[@danielniels22]

i came here for the concept though. the result is just based on inputting numbers, thats why we use computer program these days

[@J-Stew_64]

Congrats you can use a calculator

[@eduardomoreira7624]

@@J-Stew_64 it’s in case someone was comparing their answers that’s all. No need to bash me on it .

[@kslane1040]

from the formula, shouldnt it be 25, not 125 tho? since its -(sigma_x-sigma_y)/2

[@syedaliakbar5788]
