very simple but direct to the point. my professor did the same thing but toke him 2 hours and very complicated explanation. thank you so much for doing this. the planet needs more people like you
You should teach a class on teaching to professors.
Its crazy to think that teaching like this is not common. Good thing Jeff is here
University or collages are places where we learn how to learn and teach our selves, as funny as it sounds professors are not there to teach the topic but to tell its name.
the golf ball/string with the ruler on the whiteboard is such a smart teaching tool. simple and so illustrative.
That 4th problem was giving me a headache and this is the only derived solution I've seen that doesn't require some sort of monthly subscription.
sorry to be so off topic but does anybody know a trick to log back into an Instagram account??
I somehow forgot the password. I would appreciate any tips you can offer me.
that's because he didnt account for total length of the rope
Just wanted to say thank you for these videos, Im an engineering student in canada and my final exam is coming up and these videos have really been helping me so much!
I have been having the hardest time following along in my Dynamics class, but THIS video helped me tremendously to catch up and makes conceptualizing much easier!! Thank you SOOOOO much!
Thx so much for sharing your knowledge. That lesson was really helpful, this kind of content is not that easy to find with such a good explanation.
I am so grateful for another Texan translating Dynamics for me haha
Dr. Hanson, thank you so much for your videos. They make everything clearer, and your teaching style is very energetic with passion.
Keep going please!!! I'm taking this class right now
One of the best doctors ever... I am taking my static course this semester and you helped me being one of the best students in class i will be taking dynamics next semester i am really relieved now that i saw you have an online course for that .
this is my third course with Dr. Jeff, i did not watch the video yet but i am 100% positive that i will ace my tests now. huge thanks from the deep of my heart for giving us those wondeful explenations
Seriously the best of the best !
I woke up this morning not ready in any way for a dynamics test at noon. I came on youtube saw your series and watched all. I'm confident I'll pass this. thank u soooo much for this
So, did you pass ?
DR. Hanson thank you for a tremendous lecture on Absolute Dependent Motion of two Particle. I understand these problems from start to finish.
I'm really thankful to you for clearing my concepts. I referred your video since neither of my text book nor my teacher helped me
You're the greatest Jeff. Thanks a bunch
Jeff is a Godsend for all engineering students.
We will have a quiz about this in two days, nice timing 😄😇
Thank you
You are 100x better than my current professors. THANK YOU!!
JEFF UR THE GOAT THANKS FOR BEING THE ONLY REASON I PASS DYNAMICS
All your videos are so helpful to me as they increase my understanding of engineering physics material! Thank you so much for making these videos! It means a lot and I hope you know it!
the great man what ever keep it up bright man...
This golf ball example was amazing
I think these problems would be fun if the book could explain it better. My dynamics book gives like two simple examples and then the homework problems are a nightmare.
Thanks Jeff you saved me...... I have Test tomorrow on the same stuff you have covered so far.!!
you are the best greetings from Turkey
Danke schön. Completely a Course saver!
Sir you really teach well. I love the way you teach 💙💙💙
thank you so much mr hanson. this really help
these videos are really helpful! How can we get you to post the rest of the dynamics lecture videos!?!?
Go Jeff Hanson!!! Thank you so much!
10 Q alot !!!
one who learn from these lecture will be confident
I wish you were my instructor
Why dinamics part has just 16 videos???? By the way I respect to you, you are the best seriously!!
what a teacher are you !!!
Cant wait for the next lesson! Thanks again.
Hats off to you Sir!
HECK YEAH!! Dr. Jeff your an amazing professor! love your lectures!
An amazing job you have done there
BLESS YOUR HEART!
At 16:16, why is the length (b-Sc) + (Sa-Sc) and not just 2(Sa-Sc)?
someone answer this lol
It's because the length of the second rope L2 includes the rope from the right wall to the pulley labeled C and also the length of the rope that goes from pulley c to the 3m/s label (the rope with the arrowhead). (b-Sc) is the length of the first part of the rope mentioned (from wall to pulley c) and (Sa-Sc) is the length from the arrowhead to the pulley. The whole length of b goes to the wall and the length of the arrowhead to pulley c is not at the wall at this instant. Realistically there could be another datum at the right wall and you just measure the first part of the equation from that datum.
You have help me a lot. Keep doing videos.
hello sir, thank you for these amazing videos , please complete explaining and adding the remainder lessons
but on the last block B is not constant because it can be moved to the left direction untill it overlaps to the pully on its left side ... but still you are cool man keep calm man i love Phy
"You are a B because we are bad at our notation." and "Ok now its B for better" 😂
THANKS HANSON
Best professor!
Greatest man ever
Excellent video! thanks
why l2 isn't (sA - sC) + (sA - sC)
how do you pick datum lines?
That was excellent!
thank you please keep making videos
HE'S BACK!
So you should focus on the lengths of the rope rather than the direction they are moving due to the masses A and B?
that was so helpful! but how does this change when the masses are different for A and B?
King is back
The legendary Dr.jeff
thankyou so much sir for sharing.
You are an angel
Sir, I have a question: if the pulley B on the second example is stationary, how come the S_B varies on both sides of it? Wouldn't the length be the same regardless of the motion of the rope?
Edit: Thank you for that physical example with the ball. That cleared it up for me, the pulley is not stationary and it moves with the rope.
Im taking this class right now and the book is very difficult to understand. I teach math at a local highschool and the math in the book, they make ALOT of assumptions and its very easy to get lost haha
This is so useful, too bad my professor actively refuses to label rope lengths and draws diagrams very poorly.
Thanks !
Thanks ❤
Gracias !
thank you
The final solution is wrong. Va is not equal to 3 but Va-Vc =3 . Also, we should have looked for Vb/2 because B is not directly connected with rope.
How does block B have a velocity if the rope connected to it does not change?
Any chance you'll finish this play list over spring break? :-)
I know you get this a lot, but thank you so much!
he called B and C pulleys datums in the last problem which doesn't make any sense because that would mean B and C are fixed and thus nothing would move
Hi professor, in other problems ive encountered the direction of the acceleration or movement of the blocks is not stated .. how would you determine the direction of the movement of the block?
Can I get your advice on a pulley problem ?
can you make an impulse video?
Why the upper extreme right corner is blurred?? Sir
is he back? he has never left...
keep goingg !!
i am an arab and i have benefited you a lot
thank you
Having a hard time picturing why Va = -Vb, when they are both moving in the -x direction
One is moving up, one is moving down. Have nothing to do with axes.
I always wonder what is he blurring in the top right corner in all his videos.
TYSM!!!!
so whats the practical application in life of all this? whats the benefit to human?????
nice
Is dynamics this easy?
Damn! God bless you.
distinction on the way
Legend
Love the work, saving my ass right now
That last problem is giving so much trouble.
Thanks sir it really helped me and saved my time too.
All bow to King Hanson
my mom: noo son, you cant get in a gang!
me being in the Jeff Hanson gang bc he calls us gang every video: 😈😈😈
B for the best
I love you
hero
"whooooop" 😂😂😂😂
God himself
I didn’t watch yet but thank yoy
