36.2 Worked Example - Wheel Rolling Without Slipping Down Inclined Plane - Torque Method

[@joshuagriffiths3991]

Thank you, was having a spot of bother with a similar question, cleared up now :)

[@bostangpalaguna228]

well, in the case of "rolling without slipping", we can elaborate further the I = kmr^2 , right? so we got easier formula V=sqrt(2gh/(k+1))

[@devin528]

very good video's thanks a lot

[@Postermaestro]

solve for t in the first equation, substitute this expression for t into the 2nd equation and keep in mind a/sqrt(a) = sqrt(a)

[@samanthaknepp7049]

Can you explain to me why the torque here is not negative? Is it not rotating clockwise?

[@y33tboy97]

The torque explanation was exactly what I needed

[@samarpratapsingh9708]

Excellent knowledge liberating over here. Really superb!!!

[@navkhr352]

torque due to friction should be in - k direction?

[@crystal_royal3405]

Is there an faster algorithm to solve this problem

[@dhirajmahajan9263]

Sir how you find axis of rotation by
?

[@ShriJan-i3c]

Can i study it to clear jee advanced

[@NicolaeComan]

Why τ_cm=f_s⋅R and not τ_cm=m⋅a_x⋅R?

[@williamyu8995]

Is he writing all of this backwards??

[@mitocw]

The camera image is flipped using hardware or software. See this site for an idea on how it was done: lightboard.info/

[@arindammandal9378]

Work energy theorem would come handy here

[@helenli9831]

Thank you so much for this video !!

[@congsontran856]

what if the object was box would friction force cause it rotate ?

[@crystal_royal3405]

It would slide but at extreme cases it can roll (when,theta=near 90 deg,and friction =high )

[@VandanaFudani512]

Which chp is this?...

[@amitrajsingh8125]

Much too helpful

[@emmanueldavid354]

it looks like he's writing backwards lol
