I am an engineering student and everyone in our department watches your videos to understand everything. You're the best!
@Ayaan Duncan but why is this a reply to my engineering comment?
Jack Carrico 😂 bots aye, but I agree with your statement!!
had to pause just to comment, "Thats American football, that other stuff is called soccer." killed me lol
with online classes we just watch your videos. You are now my teacher :). also that 165 thing threw me for a loop i was questioning my sanity on the low.
you have taught me in 10 minutes what my professor couldnt in weeks. TYSM. you're amazing!
hey do you know any other yt profs that completes the dynamics course?
You're a professor indeed!
My regret is I didn't find you earlier in the beginning of my course in the university but since I had on my subscription list you haven't disappointed.
Thank you very much Prof. Hanson
thank you Jeff, your enthusiasm while teaching is a breathe of fresh air !
DR. Hanson, thank you once again for another powerful analysis of a Curvilinear Motion on a Parabolic Path. Calculus continues to play an important part in Dynamics.
Pretty helpful videos. Thanks a lot Jeff. Please make more videos on rest of Dynamics!!
Hi Jeff, I was wondering if you’re going to be making an Intermediate Dynamics series of lessons any time soon.
(Topics such as 3D angular momentum, types of mechanisms, degrees of freedom, and inertia tensors)
quick question. would the velocity be different when the car traveled along the curve 100m. compared to when it traveled to x=0 along the curve. Are we assuming that s=100 along the curve is the same distance as if the car traveled from x=A to X=0 along the curve. am a bit confused since we used that velocity in Normal Acceleration..
Thank you Dr. Hanson for this Dynamics course
You are amazing sir! Keep it up! Thank you for all the academic help
My words can't express how I want to thank you professor !!
We are waiting for more and more videos 😎❤
got a midterm tomorrow, these have been a life saver.
You're videos are just godly!!
😎 I now get curvilinear motion. Ur the best.
This harder problem is much better than your other videos, Which are still awesome! Thanks for all your videos!
Thanks for this amazing tutorial.
When are you going to start with structural Analysis topic?
Hi, how do we know that we have to find velocity first instead of the other? thanks
Sent down a rabbit hole...love the videos...this one threw me for a loop since I'm doing a refresh and tackling the problems before I watch your video that gives me the answer...so...S being 100, the distance along the curve doesn't happen at X = 0 for the curve function given. I did the points where it crosses the axes (0,16) and (0,100) and distance was 101.27 feet therefore I was trying to find the x that gave S = 100 which is "super gnarly" man to solve analytically...x ~ 1.6 numerically...I'd change the problem statement to "x = 0 at which S = 101.68" instead of "S=100 and x=0" which I interpreted as find at two points...one at x=0 and one at S=100.
That messed me up a bit too because he uses S which is the symbol for arc length and also s as the position variable.
This threw me for a loop as soon as I saw the problem.
But in trying to work it out I had to refresh myself on curve length formulas and parameters mixing curves. So that was good
Thank you Mr. Hanson!!
Thank you for taking the time to make these videos. I have followed along through Statics and Mechanics of Materials and am now a good ways into Dynamics. Hoping to see some Thermodynamics in the near future!
More Please!
For some reason I haven't been notified on these four most recent Dynamics videos, even though I am a subscriber, lol.
I must have swiped them away without realising it or something.
But oh well, I found them now at least. xD
Laurelindo remember there is a little bell you have to click to turn on notifications
+Jeff Hanson
Yeah, but I remember actually seeing notifications from your videos not too long ago, and I have no reason to turn that off.
I have no idea how that happened, but maybe I turned it off by accident. =P
Could you provide Material Science too?
You’re the best!!!
thank you very much!
Even your handwriting is better than mine and definitely better than my teachers haha. So hard to read/understand
first of all thanks for your effort to make it easy to understand the lesson but i have only one question
you sayed that the tangential acceleration is 0.5 ft/s*s as a givin thing but if we got the y douple prime we will find that the tangential acceleration is 0.0032... is some thing wrong
as i know that if i take the first derrivative of y it will give me the tangential velocity and the second derivative is gonna give me the tangential acceleration
the equation of y=16-(1/625)x^2 is the equation of the line path. It is not the equation of position with RESPECT to time!
that was really helpful. thanks a lot Jeff. you should teach dynamics in saudi :)
How does S=100 when x=0? Isn't S the arc length? From (0,0) to point A (the x-intercept) is 100, so wouldn't S from A to C be greater than 100?
This threw me for a loop as soon as I saw the problem.
He probably just wasn’t thinking of it too in depth.
But it’s alright because in trying to figure this out I refreshed my self on how to find curve lengths for parameterized curves.
Will you be doing rigid bodies?? I'm struggling with this atm
Monaco Super indeed. I’m just moving at too slow of a pace for you guys.
Can I ask why he didn't multiply 3/2 to 1? Isn't it (1+y')^3/2 in 11:07-11:10? So only the y' is the zero but he should also distribute 3/2 to 1 making it
3/2 divided by y''?
1 ^3/2 is still 1
please gays what is the curvilinear motion example
very helpful live long sir!
isnt there an equation for projectile motion?
I think the equation(s) you are referring to are based on time, which was not given in the problem he was doing, therefore would not be useful
down to Earth guy; a real g
get it? :D
I loved how he stopped and said "That's American football, other stuff is called soccer." :D
Jeff Handsome
Allah ayagina tas degdirmesin reyiz thank you sooo much :)
Yasıyon mu usta, okulu naptın ?
An American football field (let's call it an Aff) seems like it should be one of the standard empirical units...
S is speed noooo, super.... noooo LOOOOL I love him
İyi ders beyler kesin Bilgi yayın
Could have sworn that s was superman
Isn’t this wrong? The arc length is 101.68 so delta s is 101.6
The difference between the 2 is
.05 m/2^2 and rounds off anyway.
American football= eggball
Please move on to work and conservation of energy... exam is in 2 weeks!
It isn't soccer ffs.
"that other stuff is called soccer" hahahahah
I super love your videos. But there's no way in hell you wrote the problem statement. Way nice handwriting lmao (wrote before watching problem! HAHA you called it!)
After 6 year 😅
most of the practice problems utilize the dot-notation when finding the answer... why wouldn't you go over this important concept/application in the curvilinear videos.
Your handwriting far outperforms any of my instructors.
I just got to 1:50. your students have great handwriting.
superman hahaha
