Moment of Force Problem 1

[@RonZhang]

This video is the first video I found that discusses solving angled torques. Finally I got some useful tutorial about the more advanced torque problem.

[@ahmedkhaledmedia273]

thank you for this, the way you explained whether the direction would be positive and negative is great

Thank you so much, my professors just read the whole powerpoint about moments but didn't teach it very carefully, missing out every important parts and doesn't explain where the solution and answers come from. Because of this video, it actually enlightened me and it got clearer compared to our modules. Thank you so much!

[@LakshmiNarayanaV1212]

It's my Pleasure.. Thank You

[@nurdarwisyhah5171]

Your explanation about clockwise and anti clockwise really2 helpful! Thankssss

[@olyvya2241]

Hai from malaysia!! Thank you so much for this great video.. Im totally understand what you teach in the video.. Once again,thank you!!!

[@tomski758]

Learnt more in this better then the whole ass term of my engineering classes. Very good video for real

[@kivumbialex1120]

Great explanation... You have explained it better than my lecturer.. But in the text book clockwise is always positive and anti is negative

[@vivekjk6729]

Depends on what you want to take. Both will give same answer. If you consider clockwise positive then your final answer will be 334Nm and if you consider clockwise negative then final answer Wil be - 334Nm. Instead of writing like that, write 334Nm(clockwise)

Good example you have taken to understand force applied on body in different ways perpendicular parallel and through the moment centre.plz do more and more videos of such kind it will help many students like me. Thank you brother.

[@hugoduran5119]

Explained better than my professor. Thanks., but in the book we use, clockwise is (+)

[@LakshmiNarayanaV1212]

@@MohamedYusuf09 Its just a notation. Nothing wrong. Some authors take vice versa. If you take clockwise - then also you will get same equation.

[@LakshmiNarayanaV1212]

Its just a notation. you take the vice versa case and tell me if you get a different equation.

@@LakshmiNarayanaV1212 one doubt sir, while solving equilibrium ladder sum, I have seen all haven't considered friction at the top of the ladder to the vertical wall. It's not mentioned in the question that the wall is smooth so I am not able to get correct answer for angle of ladder. Could you help me with that sir please?🙏

[@LakshmiNarayanaV1212]

@@priyashah9466 Definitely For ladder problems we won’t consider friction when it is mentioned as the wall is smooth or the values like coefficient of friction or angle of friction or angle of repose are not mentioned. If any one parameter related to friction is given then we can consider friction and evaluate parameters related to friction.

i clearly understand how to solve it (thank you) sir

[@FemiMathew-sl5je]

Sir please which book did you use?

[@padmathapa5201]

sir... clock wise should be positive and anti clock wise should be negetive

[@LakshmiNarayanaV1212]

It is just a notation... You can take in anyway no problem. If you refer some text books some follow anti clockwise positive and some follow anti clockwise negative. Nothing wrong i will make a video on that

[@jeanatienza1247]

Can you please explain how did you get the 3cos30 and the 1sin30?

[@metaversusreality2618]

listen

[@ravindersingh3821]

If direction is clockwise then we have to take positive sign but you have done opposite

[@vivekjk6729]

Depends on what you take as as positive and negative. Signs don't matter. You have to show the direction in final answer only.

[@sankalpmathur1235]

Isn't the 20 N force acting in clockwise sense?

[@LakshmiNarayanaV1212]

No it will have anti clockwise sense. Moment center is above the force and it is at left side. Apply any one of the method that i have mentioned in the problem. So that you can know it is anti clock wise

[@nhuphuongnguyen551]

Could you please explain why distance of Force 20N is 3sin30?

[@sravanthkillamsetty6486]

hi, you have explained well. but, always clockwise will be positive and anti will be negative.if no why...

Harvard : nigga U want a scholarship?

[@geekinfo4768]

Sir at 2:28 why moment because of 60N is zero

[@laharik5476]

The best explanation

[@QnDx6]

How we calculate thre moment at point A??

[@sagarreddy1515]

Clockwise should be positive ryt. Then y uh took as negative in first force of 50N

[@yomama881]

Clockwise is negative and counterclockwise is positive. It’s just a convention.

[@wasimkhan-ge5be]

Clockwise means positive sir

[@LakshmiNarayanaV1212]

Just it is a convention. You can take vice versa also. You won’t find any difference. Solve a problem by considering two conventions, then you will understand

[@ArmanKhan-tx4gi]

Well explained. Keep it up 👍

[@ScholarStream_25]

Sir what if any force would have gone in the positive y direction then it's sense is?

[@user-wo3we2td8e]

sir, do we not have to calculate that 60N force?

[@LakshmiNarayanaV1212]

Yes.. If a force or line of action of force passes through moment center then its moment value is zero. Here 60N force line of action passing through moment center o. For this reason the moment of 60N force becomes zero about the considered moment center o

[@vinayakanil7857]

Nice video sir.. but just wanted to clarify if the sin component of the 60N force will be considered or not?

[@josephganate9272]

Nope because the force is in the x component so there will be no sin for it

[@dattatrayjiwade1553]

whether it is anticlockwise there is _ve sign or while clockwise there is +ve sign

[@likhithnarala4385]

Sir in the momentum clockwise is positive(+) or negative (-)

[@geekinfo4768]

It's positive

[@solomons6808]

Clock wise is positive right?🤔🤔

[@LakshmiNarayanaV1212]

Just it is a notation... you can consider as per your wish... It wont effect the process

[@user-wv6ln2hh4k]

i thought clockwise rotation is positive

[@Jatin-ry2fm]

Yeah it is your choice but in machenics book give us if you use clockwise then use negative sign and use anti then use positive sign.

[@sonamrinchen7539]

Thnk u....and Sir why not in clockwise direction when we calculate on 20N force.....is it necessary to take in anticlockwise direction ...it can be also taken in clockwise direction???

[@LakshmiNarayanaV1212]

20N force will have anticlockwise sense . Adopt any one of the procedure i have mentioned in this problem to find whether moment is clock wise or anticlock wise. Once go through the video completely

[@sonamrinchen7539]

THE TURNING POINT thanks sir I got it

[@jakobpowerflexer]

A was posettive = counter clockwise, then why did you put a minus before it? I

[@LakshmiNarayanaV1212]

It’s just convention Nothing wrong

[@ChanduBoddeda-s9c]

Bro for clockwise direction (+ve) and anti clockwise direction (-ve) 😂

[@LakshmiNarayanaV1212]

It’s just a convention. Just from the same problem if you take vice versa you will get same answer.

[@enavaneetkumar6964]

According to sign convention clockwise Moment is positive and anticlockwise Moment is negative

[@LakshmiNarayanaV1212]

It is just notation.. you can take the sign as per your wish... Here i have followed standard notation... just take the notation as you want.. Finally you are going to have the same answer without any change. Just try it and give me a like

[@saivaraprasad7545]

Sir but our faculty had thought that it will be +ve for clockwise direction in other video i have seen it is also as +ve.

[@ex.martian]

You can assume it as you like. Either +ve for clockwise or +ve for counter-clockwise

[@saketaram]

Sir please solve some more examples on moment

[@amargamingyt7809]

Clockwise means positive,?

[@LakshmiNarayanaV1212]

Just it is a notation. If you consider the vice versa case also there wont be any difference

[@florence722]

Thank you so much 👍🏻👍🏻

[@jamesspillner9601]

In convention clockwise moment is taken as positive but taken as negative How?

[@LakshmiNarayanaV1212]

Just it is a convention. If you take the sign vice versa nothing will change. Try once and tell me if you find any difference. I did tried. No difference

[@abhaykumar-dq8so]

clear concept thanks

[@anambashir5923]

its very helpful

[@michaelokaysin4239]

what happened to the 60N

[@LakshmiNarayanaV1212]

It’s moment is zero as it’s line of action is passing through the moment center

[@michaelokaysin4239]

Thank u

[@mohammedsaadsanderwale4509]

Clockwise direction means +ve.. U taken -ve

[@shivamgautam106]

I have a question We can easily break thin long wood but why we cannot break same wood of small length?

[@LakshmiNarayanaV1212]

Because as perpendicular distance increases moment increases. If length is more then moment of force magnitude is more and if length is less then moment of force is less. M=F.d With out increasing the force if we just increase distance then we can have greater value of moment of force.

for anticlockwise we have the sign +ve but why you use -ve sign plz send ans

[@LakshmiNarayanaV1212]

It is just notation.. you can take the sign as per your wish... Here i have followed standard notation... just take the notation as you want.. Finally you are going to have the same answer without any change. Just try it

[@laurenceguy4217]

It is either way. As long as you complement the opposite rotation youll come up in a same answer. Its the same with: (2x + 4y = -32) and (-2x - 4y = 32)

veerkumar gandigude answer comes the same

[@mohanking5187]

But anti clock wise direction is negative

[@thombaresurekha533]

Bhaiya clockwise +ve hota hai Aur anticlockwise - be hota hai

[@LakshmiNarayanaV1212]

Its just a notation. You can take the other way also

[@mohamedarab6187]

i don't understand why you didn't and the distance together of the 20 N force but you add together the 40 distance force i mean why 40(4+3 cos 30 ) and not 20(4+3 sin 30)

[@LakshmiNarayanaV1212]

Because always you need to consider perpendicular distance from given moment center only

[@harambematata416]

still didnt get it . about the usage of clock and counter clock wise direction

[@varunsisland]

Imagine a windmill at the point where moment is asked. O in this case and consider all the forces as wind. Now 20N at C is a wind and it'd move the windmill counter clockwise. I hope it helped

[@vamany6043]

About moment of 60N

[@LakshmiNarayanaV1212]
