Physics 13.1 Moment of Inertia Application (5 of 11) Object Hanging From a Rotating Disk

In this video I will find the acceleration, a=?, of an object hanging from a rotating solid disk.

Next video in this series can be seen at:

You will be forever remembered for your services. Students around the world are grateful, thank you so much!

I once went to a presentation where the speaker's theme was that true success is making a positive impact on the lives of others. You sir, I can tell is truly successful. I cannot thank you enough and you are the hero we all need.

Simply amazing video. I've seen many videos of physics problems on the internet but you're really quick to get to the point, amazing resolution of video, overall congrats man.

I was pulling my hair out over a similar problem involving finding the radius. I completely missed the obvious definition of using the tension given to me to find it. This video opened my eyes to that. Thank you very much.

5 years later and thank you for this. Current teacher is very bad at teaching (shows in how many students dropped the class and the last exam class average of 53%) and this just taught me most of my exam tomorrow.

your have really nourish me in physics my thirst of being physics teacher is now quench, thanks so much sir we are ever grateful

[fariss]

It helps me during my ODL at home, a huge thank for you Sir

[avinashbiradar]

basics are explained in very simple and easy way.... Great teacher

[theposercrusher]

Lovely bowtie, nice explanations! This guy knows what he's talking about!

[faridisayev]

Amazing as always. Waiting for new videos!

[mileslegend]

Few seconds watching this...and my mind has just opened to the realities....🔥🔥🔥thank you so much

[jeson]

Your tutorial vids rock!!! they are the only one I download in 1080p.. help i find more when i need them...
Q. when calculating torque for such a system, why dont we use the Fnet that comes from resolving the forces acting on the mass?? why tension and not Fnet?

[jeanjoubert]

Thanks for the great video. Just one question. Using vector equations r x F I get -Ri x -T j = RT k (ccw) if mass is left and Ri x -Ti = -RT k (cw) if mass is on the right but equation at the mass : ma j = Tj - mg j stays the If the mass is left, do I just change the sign of T so it is opposite a??

Sir your video are very helpful can you please make some videos on pure rolling and combine rotation and translation motion

[grantallvin]

Thanks so much for this! I was racking my brain around a similar problem and this really helped. :)

[thantran]

Thank for great video! It's very helpful to me

[polxnsw]

Thank you so much sir.
Your videos are really helpful and I am extremely grateful to you.

[zuhairalsaffar]

You are perfect teacher my respect for you

[aidanwhitecars]

Hi Sir
These videos are great.
Is there a video that shows how to work out the rotational speed of a flywheel as a result of the energy transferred from the falling mass?

[zuhairalsaffar]

You are the best l like your way of teaching thanks
