Gyroscopic Precession
bicycles reviews | bicycles videos | bicycles online
NOTE: This video will appear in a playlist on Smarter Every Day hence the references to Veritasium. Destin does lots of cool science stuff - check out his channel if you haven't already http://www.youtube.com/destinws2 We have been collaborating on rotational motion, which is timely for some of the videos I've been doing lately. In this video I talk about gyroscopic precession - the "wobbling" of a spinning top around its axis. This is caused by the torque due to the object's weight. The big idea is that the torque vector increases angular momentum in the direction of torque. So if there is no angular momentum initially, it will cause the system to swing in such a direction that it is rotating with new angular momentum in the direction of the torque. However, if there was angular momentum to begin with, the torque will change the direction of that angular momentum by causing precession.

hmmm please watch vsauce video at this its so different i dont know wich one is right

(2:34) Could PLEASE anyone explain me why this mentioned torque goes/points that way (to the camera)?
-
What if 2 or more gyroscope axles were connected at angles? Could the resulting torque be found by vector addition?
-
warnnig jump scare at 3 42😱😨
-
Sorry man this is not good explanation, whats up with memorizing hand rules,?! Just explain torque momentum and gravity falling effect that constantly battle!, resulting in new vector that moves also constantly side way= rotation.
-
damned faggot i crapped my pants when the wheel had cut your head.
-
Is it slowing down because of friction, or is it slowing down because the torque cause by gravity is opposing and slowing down the angular momentum? Would it not fall the way it did in a "frictionless" environment?
-
What does this have to do with precision?
-
You mispronounced Veritasium.

"I'm gonna bohrow some of their electric equipment," lol. Bohrow.
-
Can someone explain to me what torque is? And why does it have the tendency to go out (perpendicular) toward me in the first place? Thanks!

Tuen this fuclinh wheel ans shut up
-
Although torque is a pseudovector, right?
-
wow your heart is bad, after spinning the wheel u get breathless.
-
torque is r x F. and not F x r
-
Hm, you are lucky because your camera has low latency, otherwise you will be sacrificed for science :)
-
Great vids,, I just understand why it's rotating clockwise.... "The torque and angle of momentum" :D :D :D

Torque : Force x Distance. Bicycle pedals. Simple Lever. Larger the distance between point of application and the pivot, larger the Torque.
Precession. When a force, Torque is applied to a Gyroscope, the force effect precesses 90* in the direction of the rotation. Eg. When riding a bicycle, hands free, when I bank left, the the force applied at the top of the rim, pushing it left, precesses forward by 90* in the direction of the rotation of the wheel, and turns the wheel Left. ie The Torque on top of the rim, instead of left tilt, it gives left Yaw. That is precession.
