The way he says "we only want the z component of the torque " is confusing because it gives the impression that there are other components when in reality torque is defined as being perpendicular to the axis of rotation. He should have instead said "we know that the torque vector is directed perpendicularly to the axis of rotation, therefore to compute the torque we can ignore the k hat component of the force when taking the cross product with r because the cross product of r with the k hat component of the force is not perpendicular to the axis of rotation.
I've been trying to understand (not just grasp the formula) how torque affects acceleration for several weeks now. Thank you for this derivation.
That is amazing, excellent school
It seems the polor coordinate i, theta and k prevail everything in rotation.
Nice work
Hi can you please explain me difference between kinetic energy =1/2 Iw2 and angular torque t=I.alpha As for both unit is same NM.
I WANT TO CALCULATE MOTOR POWER BY CONSIDERING TORQUE BUT STUCK IN ABOVE DOUBT PLEASE CLERIFY
Torque times angular velocity should give you power. I would go through the equations again
is he writing the mirror image of what I am seeing?
Ayeèee, how is he writng like this 🙆
How's he writing backwards? What's happening? lol
I'm 14 years old and this was very nice and helpful, thanks so much
I'm 1 year old and this was very nice and helpful too :)
I didn't born but this video is also helpful for me ... thank you :)
I am dead
