- This video demonstrates the concept of Torque, a.k.a. Moment or Moment of force.

Here are some notes:
1) Torques are often mentioned in context of engine power and transmission gears. Engine manufacturers usually specify the maximal Torque (T) their engine is capable of producing. If you know the radius (R) of the gear attached to the engine, you can compute the force it exerts: T*R. Transmission gears along the way to the car wheels can increase or decrease this force.
The following video explains that using the concept of engine power: • Cars: engine power and...
2) Many scales don't have a straight lever, but instead a downward bending lever. This produces the same effect of placing the points where the weight's forces are applied below the pivot, as explained at 1:37-1:55.
3) The video gives a visual definition of "cross-product". It is slightly different, though equivalent of course, than the traditional one. In particular, the vectors are placed one following another instead of placing both at the origin, and the right-hand rule is shown differently.
4) The last scene in space: this is a more general example since the object is not attached to a pivot, so it can arbitrarily move and rotate. The situation where there sum of forces is zero is a special one: In this case the object will not move but it may rotate, depending on the torques. Also special in this case that one may calculate the torques about any point (i.e., any point may be chosen as the pivot) and the torque vector result will be the same. From the symmetry of the object shown we now the true pivot will be in the middle.

"Now a more general example"
"An octahedron is floating in space"
Ah yes, finally something I can relate this to.
I was about to comment the same thing xD
I can relate to this because of Super Mario Galaxy.
It kind of hurts my eyes just to look at it. it almost looks like an impossible object
General by definition means something (a rule of thumb) that works for all values in the set of real numbers or a bounded domain. General does not imply easy. It just implies precise.
Generally, octahedrons DO float...in space...
I am so thankful to the developer of this animation when your teacher asks you to visualize torque by just explaining it, to be the cross of R and F.
So this is why my scrap mechanic machines never work. Thanks floating octahedron!
You're doing some excellent educational vids!
What a great video! This really helped me visualize torque, amazing job, thank you so much!
very good demonstration. I appreciate the 3D animation and the work done!
one of the great video with more simplicity i have ever seen on you tube!!!!!!!!!!!! keep it up!!!!!!!!!!!!!!!!!!!!!!
The area representation of force is brilliantly intuitive
Magnificent ! Thank You.
The greatest creative minds are those which can visualize.
Rock on
This is incredibly clear and easy to understand. Thank you!
Great video!
Perfectly explained 👍🏻
such a great explanation even 9 years later
Best Educational video I've ever seen :D
Nobel prize for visual explanation!
the animation at the end really give me the sense why do torque vector is perpendicular with the force and the 'r' vector
it will rotate like a screw
These videos are awesome.
just awsome....I've understood the concepts of torque in the best way....💖
please sir, make much more videos like that
You helped solved my confusion. Thank you.
awesome doug, nice job
Great animation! thank you so much!
Que buen video mejor explicado imposible!
sick...this is excellent stuff
Finally got to understand it, thanks
This video doesnt require ur funny comments, thanku so much for this vid, helped me a lot❤️❤️
PS, Please stop those ocahedron in space, relatable " funny " comments in good educational vids, but whatever u do what u got to do so cheers!!
thanks so much! It was such a clear vid :D
Your videos are really great! BTW when are the RockerSpaniels getting back together? :)
very nice animation
I LOVE this
Thank you for a fantastic video! I got it :D "Each purple rectangle represents a Torgue!"
Thought this video was memeing at first with the rocker spaniel sponsorship... great information though!
that was awesome. I wish we had that in school.
Thank you so much!
that was AWESOME O_O
I never realized that the lever would need to hang below the pivot in order to balance out.
Bravo!
1:36 You mentioned the the lever is slightly below the pivot, which is one of the crucial parts of how torque works. So what happen if the lever is exactly *on* the pivot? Does torque still appear? If yes, how does it behave?
Yes, the torques will still appear. But they will be perfectly balanced for both weights. So the rod will stay where you leave it, even if it's not horizontal. This is like a ferris wheel with just two carts.
This video explains it so well, it's painful.
What is the point of using pseudo-vectors?
why there is a subtitle for Hebrew
why rectangle are torque?
Amazing clarity. Please replace the dry educational system with your visualizations.

If you see a floating octahedron, you need to get in the goddam robot!
I know this beside the point but since the octahedron was in space the jets wouldn't operate. You most likely meant rockets. Sorry, I just had to say it. Lol. Love your channel and your videos are awesome btw.
how to understand the concept...i could not understand:(
but the video is great:) Mashaallah:)
Afiqah Matnor This shows the way the physical concept of torque. If you don't fully understand what exactly it means or don't understand the cross product, try thinking of it intuitively and then connect these two. Maybe you'll even get an intuition for the cross product!
Gravity gets weaker the higher an object goes
All the diagrams just said the same thing over and over.
Look, center of mass is a thing that exists.
