Thanks Sal, I remember I was terrible @ this stuff in high school. Now I'm at university and I need to know this stuff for a Biomechanics unit, so much clearer now.

You're amazing for refreshing my pre-university memory keep it up :D

twerk.......... now im understanding moments of a force!! thank you Khan

mate in a short video ive learnt more from you than my physics teacher.... you made it so easy to explain..

guys he mentions that he kept mixing up clockwise with counterclockwise near the end just go with clockwise and counterclockwise as you would. he was just mixing them up on accident

I'd love to see a lot of beam deflection problems using calculus. Simple span two point beams with multiple loads and cantilevers - but not all at once. Thanks so much love your work!

oof almost a million people saw sal getting confused with clockwise and counter clockwise xD if you view the same video on the ka website a small pop up corrects his mistake

Sal I think you may have just saved my life! THANKS SOO MUCH!

Sal...you are the man. Thank you.

U explain so nicely and clearly

wonderful and a highly conceptual video......simply amazing......like ittttttt....!!!

Thank God! I'm so happy Dr. Khan made a video!!

Moment is simply just a rotating force around a specific point/pivot. You can start with this simple meaning

Excellent teaching style. Thanks.

oh my gosh I was 4 when this video came out, now I'm in college and this guy has helped me get through calculus, chemistry, and physics many many times. thank you sir you have been a blessing in my life

god bless khan academy

LOL dude! Nice lesson! I actually learn a lot + it is fun. I love it, thanks a lot, I got a hard time understand this.

"i don't know... lets say its 2 " - damn , did i laugh so much :)

Good Video, Confused about The CCW and CW parts until you corrected it at the end. But still very helpful

Brilliant explanation. We got the clockwise/anti-clockwise, thanks again! 👍

very nice, this is a review for me but your confusion of counter-clockwise / clockwise every now and then is funny, making the tutorial quite refresh and not sleepy

Sal, you are great. Just a little correction: Im afraid that you did confuse the clock- and counter clockwise directions at about 10 minutes. But Its common sense. Best regards from Serbia

thanks, this helped alot :)

Thank you so much!

basically the closer the object is to the pivot... the more effort ( force ) required ?

this. was. twelve. dang. years. ago. and yet his way teaching never fails to teach me : )

for the last time, clockwise = --> this way counter clockwise=

finally I undesrstood thanks Sal

thanx mate!

Thanks a lot!

THANK YOU SO MUCH....

dude you're amazing i love this!

this was very good.. i get it now!!lol.. im in 10th grade and when im studyings physics for exams this is so helpful!! thanks=)

Hello Sir! I have a question regarding the direction of a force. How can I determine if a force is clockwise or counterclockwise? Could you please provide some guidance or resources on this topic? Thank you in advance for your help!

Ah! I sure wish I found this channel earlier! But thanks too anyway.

Oh shoot! I gotta watch this! I'm so lost @ my Engr. Mechanics right now and I don't get the magnitude of the moments stuff!

I got it ......and, as a teacher myself, I have some sympathy for the guy here. Some days are just harder than others. LOL.

Its actually really nice thanks

oh thnx god, this video save my live!!!

QUESTION - Any explanation of "moment" or "moment connections" must start with the etymology of the term "moment" which is crucial for me when I try to understand anything. So any layperson, when they think of the term "moment" is in reference to time. A "moment" of time. So now that we are apparently repurposing the term "moment" for torque etc can you explain why it is called a "moment" to begin with? How is the term "moment" in reference to time used here or are we redefining the term specifically for physics / Engineering?

@vladuz1001 Always remember this formula: F=ma where 'F' is measured in Newtons(N), 'm' is measured in Kilograms(Kg) and 'a' is measured is Metres per second squard(M/s^2). 'a' is usually 9.8m/s^2 when you're talking about forces acting perpendicular to a surface. If we apply F=ma to your problem: 1,294(N)=m(Kg)x9.8(m/s^2) You're trying to find the mass, or 'm', so we divide both sides by 9.8 to make 'm' the subject. 1,294/9.8=m Therefore m=132Kg

thanks a lot.

RIP Clockwise and Counterclockwise.

thanks dude

thanks bro!, you helped me a lot, keep up the good work!!!

THANK YOU!!!!!!!!!

Come on guys, understanding the graph and method is wayyyyy better than complaining about clockwise and counterclockwise, this this case, u just need to know the force direction is different and put them in opposite side of the equation.

thanks a lot for the video. great help to students like me.

How do you determine the unknown force as clockwise or anticlockwise? Or you just assume

got it!

This was great! ;) ;)

Cheers Sal

Dear Salman , plz dont bother that you clouded the directions in the last case. Know that you're an amazing teacher and we love you a lot.

thank you very ,much

that's not counter clockwise 😒

Would you do a presentation on torque created on a archery shot where the hand meets the bow?

Thanks 😊

Same with me, I really am having problems about the rotation, whether its a C or a CC.

just use right hand rule for the sign convention of clockwise and counterclockwise. I finished this in half the time it took time to explain

"It always becomes a lot easier when you do a problem...except when you try to erase things with green" lolololol.

11:00 24N*8ft would work very nicely.

If I screwed up a video explaining a simple concept such as this as badly as this guy did I would re-do it.

You say clockwise and counterclockwise backwards at 11:00. But thank you for the great video[s]!

How is that counter-clockwise ?

i was confused in your video.. please make it better and correct for the next time around.. Thank you..

your better at teaching than my science teacher

Look its easy, just think about trigonometry: your angle is positive as it goes counterclockwise and negative as it's going clockwise. if you can just keep that image in your head, everything becomes pretty straightforward as far as the direction of torque goes.

Well its like making mistakes while teaching really works i totally get it now 😆 🤣

Nice class sir

Hey Sal, I've been looking at dozens of videos and wikipedia pages, but I can't find a formal proof for why M = Fr. Can you do a video describing the formal proof behind this formula? Cheers

@artroaster9886

its not angular momentum its troque for angular momentum it will be momentum times the radius

There's a problem with rotation direction but the computation is correct since it is to be equated to zero for the system to be in equilibrium.

yes dude you r right

omg the clockwise and counterclockwise stuff was so frustrating. here's a simple trick, clockwise goes in the same direction that a clock moves. lol.

Legend has it that under those black rectangles, there is infinite knowledge

"I keep mixing up all of the clockwise and counterclockwise"

it really helped me in some points but when he pointed the clockwise and counterclockwise ...

@jamieskill. 10 is an estimate for g. Since 10 is much easier to use mathematically it makes sense to round to 10 instead of multiplying or dividing everything by 9.81, especially if taking a test without a calculator.

Please make an HD video of this

For all of you guys confused wondering if he got clockwise and counter-clockwise mixed up, he didn't. That's how torque works.

Arigato!!!

@goldensilverstar He corrects himself at 13:36 but the concept gets across if you don't get stuck on that one detail.
