Professor Hanson... You sir, are a legend. Thank you for posting these videos, I'm studying for the FE exam and your videos are helping my relieve an enormous amount of anxiety!
I had to stop and just say "Thank You" for the laughs you create with your jokes and demeanor. It keeps us engaged and constantly absorbing info.
I feel more engaged in these videos than any of my lectures over the past three years
its a joke comon
Literally best explanation ever
Awesome videos. I'm not sure how my instructor never thought to explain the concept of making a cut where the object will fall. That is so succinct and so helpful in figuring out how to start the FBD.
Professor Hanson, thank you for an excellent introduction to Pulleys.
by far, the most passionate teacher Ive listened to
Thanks alot for all your videos you have helped a lot of us...
Studying for an exam. Super helpful, thanks!
You remind me of my old history professor, Mr. Scott, except you have a sense of humor.
Pulley problems are nothing after watching this video. Waiting for my next exam to crush the pulley problem. Thank you sooo much
Wonderful Statics lessons!! really taking the time to explain the problems along with a good sense of humor :))
Ive finally understood pulley. Thank you very much sir
I don’t usually comment but for this have to say thank you for these videos..
The I know we shud be on the metric system too killed man
Fun while learning is rare
Thank u so much u 220ib MAN😂
In the man on platform problem, isn't it a mechanical advantage of 4t (not 5t) and the section of rope the man is pulling on, allows him to pull down rather than pull up which would be awkward.
why did we count the redirecting rope as a tension rope in the 3rd problem?
can anyone explain why there are only one rope in the problem with the man? why don’t we count the 2 ropes tied off to the platform?
I expressed all tensions in terms of T, and then I found the tension that had the highest factor of T (in other words, 2*T) and set that tension to 1500 N.
Another method: Let tension T1 = 1 Newton, and find the tension in the remaining pulleys on this assumption. Then scale it up, until the largest tension is 1500 N.
I can do all things, through Christ who strengthens me - Philippians 4:13 👍👍
Metric system rules!
I wish I doodled more in school so I could draw these amazing pictures.
Good stuff! Thanks!
love you doc
Nice Shirt!!
Why wasn't T1 set to 1500 N as well?
Thank you man ❤️❤️

Race guy Jeff 👍
It's unfair to call T4 and T5 the weakest links, they're just the ropes being subjected to the most weight. Maybe if T1, T2, and T3 helped out a little more, T4 and T5 wouldn't have to carry so much
eye opening
Who even disliked this video...
I felt insulted I'm 60 Kg 😡
