[@harshbhamuvani8688]

Please finish this course Dr. Hanson.....we all need youu😂😂

[@catchurlifedhk557]

Harsh Bhamuvani i totally agree..... I need help

[@adapperdisguise5697]

More dynamics please good sir, my dynamics professor is new and I’ve learned everything so far from here..... save me please

[@xXxKingProductionxXx]

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!

[@landshark1655]

Studying for my dynamics exam in Australia and this has been an awesome help. Thanks Dr Hanson

[@brandonaller8614]

Seriously please continue in dynamics!!! You help me understand it so much better then anyone has

[@fei9566]

Dr. Hanson, thank you for making these amazing videos. Hope to see more soon!

[@RyderB26]

Thank you for the amazing videos! I'm in this class this semester and these videos have done wonders. Anxiously awaiting the next video

[@georgesadler7830]

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.

[@billydotson3598]

Following these videos for 1.5 years now. I study mechanical engineering in the Netherlands.

[@keshavkalsi3039]

Will you please make some more videos Mr Hanson. It would really help me in this course.

[@nahomdiro7163]

more dynamics please good sir, my dynamics professor is new and I’ve learned everything so far from here..... save me please 16

[@killrfox916]

Please make more videos you are great at teaching!

[@Peter_1986]

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.

[@NeverendingAbyss]

finish the fight, professor.

[@yusufsoliman4762]

are you gonna continue?

[@ryan355]

These are great! Just got me through my first test. Any chance you have more for Dynamics? Thanks for all the help!

[@jackbryan5851]

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.

[@Baggrav]

Mister Jeff , please , complete the course , you are our only hope

[@joshuas3897]

Thanks for the great video Jeff you truly are an amazing professor!

[@priyabhowmik6227]

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)?

[@blackbird7531]

Thanks Mr.Hanson

Thanks Jeff

[@yuriykovalov2936]

Dr. Hanson, i think i speak for most of us..... Could you please continue this course?

[@davidbenter8137]

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)?

[@johnandreibatac4141]

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

[@dinoksettid]

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?

[@gustjohnson2727]

Thank you!

[@edinalibasic142]

Hey professor hope is all well, please consider finishing up dynamics course when time permitting! Thanks for everything

Best thumbnail I've ever seen.

He looks pissed in the thumbnail, like "I dare you to watch this video...!".

[@jimmyyau7258]

i love the red vest on jeff hanson, he's a fashion icon

[@heavyymetal]

Why do you say the centripetal force pushes it up the rod? Doesn't it pull the rod towards the centre of rotation?

[@faisl9132]

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 (:

[@Lexyvil]

I thought the normal force always pointed towards the center at the point of curvature. Can anyone explain me why it's pointing away?

[@rainfalling123]

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

[@plainnessmanifestor7278]

Jeff the best instructor this world has ever fucking seen

[@davidcortezchuks6467]

Dr. Hanson what textbook do you use or recommend

[@moisesdedios9624]

Dr. Hanson, our next lesson is Equations of Motion: Cylindrical Coordinates. Hope to see this one good sir!

[@ahmadhamdan7679]

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 ,

[@chenlmbd]

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?

[@1234jhanson]

I’m in Spain for the summer, definitely continuing with videos

Why does f(x) and f(y) equal to zero?

[@johnbarneswood]

Please make more dynamics videos soon!

[@tevinabeysekera6038]

I love being able to pause the video and think about the problem compared to hearing my professor talk nonstop.

[@alic211]

pleeeeeeeeeeease complete all lessons dude

[@giorkospetrou]

Isn't the centripedal force acting towards the center of rotation instead of the opposite as it is shown on his HBD?

[@marwanshamsia]

I don't know this is very confusing for me,

Can you do rigid bodies force and acceleration, rigid bodies work and energy and also rigid bodies impulse and momentum

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.
