my final exam in 11 hrs and 35 min! and I was killed by thinking Torque was equal to Force * lever arm * cos/sin of Force, awesome and great explanation for simple torque.
so this definition is the same as the cross product of the position vector and the force vector (where the position vector originates at the axis of rotation)?
Matt Anderson okay, so say the rod was hinged in the middle and 2 equal and opposite forces acting as a couple are acting on its end (no translation only rotational). Like on a magnet in a magnetic field. So do we calculate the arm length sine component from any one force to the hinging point or to the other end where the other force is acting? I realize this is a little late but then physics hasn't changed in 2 years I hope
Contrats. How can I calculate the angle of a seesaw when two masses are different? Let's say 10 kg one side and 15 kg the other? What is the resulting angle? If distances are the same.
Eazyy e (that was a great song from the 90's), Yes, of course the lever arm can be perpendicular to the force. Then Φ = 90˚ and sin Φ = 1. Cheers, Dr. A
One of the best professors I've ever seen. Nice.
Amazingly explained. Well another way to define lever arm is...it's the common perpendicular to force and line of axis. By the way GREAT video👍

so much easier explained than in uni physics with modern physics, thanks :)
this was a simple and easy to follow explanation thanks!
Felix,
Thanks for the feedback, and stay tuned for more videos.
Cheers,
Dr. A
The best Physics teacher in the World !!! 😎
the colour of that marker is awesome! Great video! :)
Sir how can write on a glass, nullifying the effect of Lateral Inversions

good job Mitchell
very simply explain lever arm. clear concept....great & nice video.
Madhav Mishra,
Thanks for the comment, and keep up with the physics!

WOWOW THAT WAS AMAZING THANK U
Thanks doctor ❤
Thank youuuuuuuuuuuuuu
I have memoried this lever arm
But now I know what is going on in tourq
Good Professor
I am going to be a better Teacher.. though I long to be a professor too..thank you Professor
Keep going, you can do it.
Cheers,
Dr. A
I wish you were my professor.
thnak u sir... for ur easy explaination,,,,,
Great Video!! Thank you
good video thank you very much
Very useful, thank you!
This was sooooo helpful
Wow thank you so much this is so cool
Excellent. Thanks for the shout out.
Cheers,
Dr. A
thank you
Thanks
Anytime. Have a great day.
Cheers,

THANK YOU SO MUCH!!!!
YOU ARE WELCOME!

1 in million
How is he writing like that????? Like backwards???? (also good video) :)
Brigid Mark maybe by mirroring the Video
+james paxton
I tried that. It's kind of hard. So I don't write backwards.
See: ruclips.net/video/CWHMtSNKxYA/видео.html
Cheers, Dr. A
+james paxton
I will need to practice writing backwards a bit more, if only to freak out my students every now and then.
Cheers, Dr. A

can the lever arm not be perpendicular to the force?
Eazyy e (that was a great song from the 90's),
Yes, of course the lever arm can be perpendicular to the force. Then Φ = 90˚ and sin Φ = 1.
Cheers,
Dr. A
but there are live people listening in there, how can they see it backwards?

I have a big monitor next to the glass with the flipped image.

Cheers, Dr. A
He Kinda looks like Dr Strange 😂
Thanks. Not nearly as cool. But I do wave my arms a lot.
Cheers,
Dr. A
OMG,......This is a College course ? hahahahahaha
