Please finish this course Dr. Hanson.....we all need youu😂😂
Harsh Bhamuvani i totally agree..... I need help
More dynamics please good sir, my dynamics professor is new and I’ve learned everything so far from here..... save me please
Profesor Hanson, you have helped me greatly with Statics and Mechanics of materials, could you please make more lessons on Dynamics? You are incredibly helpful and an amazing teacher, and learning from you just makes sense!
Seriously please continue in dynamics!!! You help me understand it so much better then anyone has
Studying for my dynamics exam in Australia and this has been an awesome help. Thanks Dr Hanson
Dr. Hanson, thank you for making these amazing videos. Hope to see more soon!
finish the fight, professor.
Thank you for the amazing videos! I'm in this class this semester and these videos have done wonders. Anxiously awaiting the next video
Professor Hanson, thank you for another awesome lecture on Equations of Motion, Normal and Tangential Forces. These videos continue to be helpful in all levels of science and engineering.
more dynamics please good sir, my dynamics professor is new and I’ve learned everything so far from here..... save me please

Following these videos for 1.5 years now. I study mechanical engineering in the Netherlands.
Thanks for the great video Jeff you truly are an amazing professor!
you make me love dynamics :) You are great Mister Hanson!
Will you please make some more videos Mr Hanson. It would really help me in this course.
These are great! Just got me through my first test. Any chance you have more for Dynamics? Thanks for all the help!
Mister Jeff , please , complete the course , you are our only hope
are you gonna continue?
Please make more videos you are great at teaching!
I have a question when doing your sum of forces in both the x and y why didn't you set it equal to ma. In the y direction couldn't you set it equal to m(at)?
You need to get one of your students to 3D print you a holster for that calculator. I like what you tried sticking it on the board. The holster would give you the best of both worlds: easy board mounting for quick use and quickly retrievable for complex calculator work.
These videos are based on the book "Engineering Mechanics - Dynamics" by R.C. Hibbeler.
That book is great, it has a very large number of example problems and review problems, so see if you can find it at a library somewhere.
Anybody know if the course is already completed, or are there lessons missing?
Why do you say the centripetal force pushes it up the rod? Doesn't it pull the rod towards the centre of rotation?
If you rotate the FBD axis so that the weight force is vertical, this leaves the friction force only acting in the new X direction. From this I got a completely different answer for Normal force, as friction should not affect the normal force. Doing this I got Nb=11.772 rather than 28.85. What am I doing wrong? Is rotating the axis the issue or am I forgetting a force?
Dr. Hanson what textbook do you use or recommend
I thought the normal force always pointed towards the center at the point of curvature. Can anyone explain me why it's pointing away?
how did he break the forces into components like the 3/4(.2) (Nb) and 3/5(Nb) and why did he times it with Nb , I tried but could not understand it ,
Hey professor hope is all well, please consider finishing up dynamics course when time permitting! Thanks for everything
Thanks Mr.Hanson
God? Is that you?
Dr. Hanson, i think i speak for most of us..... Could you please continue this course?
Dr. Hanson, our next lesson is Equations of Motion: Cylindrical Coordinates. Hope to see this one good sir!
Jeff the best instructor this world has ever fucking seen
Please finish this series :-:
Can you do rigid bodies force and acceleration, rigid bodies work and energy and also rigid bodies impulse and momentum
I love being able to pause the video and think about the problem compared to hearing my professor talk nonstop.
can you please upload the rest of the curriculum? I have finals in a week and I need your divine intervention to not fail this class
we need the rest of the course!!! my grade depends on it!!
youtube has the best teachers
i love the red vest on jeff hanson, he's a fashion icon
Thank you!
Why does f(x) and f(y) equal to zero?
Please make a video on work and energy! Thanks! :)
Thanks Jeff
More dynamics lessons please, save us ):. great Thanks for your helpful channel . Many students in my university rely on your Videos and you have because famous teacher (:
Sir, we need more videos on Dynamics ASAP
Isn't the centripedal force acting towards the center of rotation instead of the opposite as it is shown on his HBD?
I don't know this is very confusing for me,
Best thumbnail I've ever seen.
He looks pissed in the thumbnail, like "I dare you to watch this video...!".
Can you upload next videos please.
Please make more dynamics videos soon!
thank you
please make more videos Dr Hanson
Another question, SO if .25m is the Diameter shouldn't the radius be 0.125m and then we use this in our equation for Rho would be (4/5)(0.125)?
Its not the diameter. (I think he didn't say it's the diamter either)
.25 is the length from A to B going upward. When the spool moves in circular motion, the x component of that .25 is what u need for An
can you please make more video about dynamics???i really need your help with this subject...help me pass my exam please,sir
more dynamics please good sir, my dynamics professor is new and I’ve learned everything so far from here..... save me please

i am africa and.........
yay!
pleeeeeeeeeeease complete all lessons dude
Still, no new video is uploaded😥😥
I wish my teacher did problems this simple.
Dr. Hanson, please come back! We need you! The world needs you! If you don't want to do the videos anymore, can you at least finish the Dynamics course?
I’m in Spain for the summer, definitely continuing with videos
@@1234jhanson Thank you! Thank you! Thank you! Thank you! Thank you! Thank you! Thank you! lol
Please more dynamic
Save us please.
New drinking game: drink every time Jeff loses his calculator
Please continue!!!! use the FE NCEES Reference book as a guide ... not that you need it.
"Nuh uh I dont like u to slide" 😂
You are a great teacher but why when taking my test I blow up; but when following your examples feel like I'm getting the subject.....
heyyyyyy dear my own teacher, if I"ll be honest, ı have really missed you okayyyyy all right let us gooooooo
If you had a patreon I'd donate!
yo man looks like Walter White from Breaking Bad
I hate when example problems add a lot of useless information just to trick me, like for example a "mass m" that will never appear in the answer and crap like that. =P
please make more videos
He has said in a recent video that he will make more videos - not sure when they will be uploaded though, but sometimes he posts a whole bunch of new videos all at once all of a sudden, so you could look forward to that.
@@Peter_1986 good news, I hope he posts them before the finals
@@mohammedalsaeedi9417
He talks about Dynamics in his "what's next?" video, which was posted right before this video.
I swear that calculator has feet!!!
my nigga!
First
Hello sir. I am a lazy piece of shit and my final is tomorrow. Watched all you recorded. Wish me luck!
