2. Equilibrium of a Body

[@johndoh1000]

This short video gave me a much better understanding a whole semester of college gave me

[@skystalker2]

I seriously wish I saw your channel while I was doing my first year of studying engineering

[@rasc0030]

I can not believe it has only 400 views so far ... Great content. Keep up the good work. Thanks for sharing.

[@qdeanc]

This is so incredibly helpful what the heck

[@richardxavi2216]

best video...ever seen ... congrats Waterloo ...way to go...pls post these kinds of videos

[@vilivont4436]

Beautifully explained!

[@vishaldeokar5470]

All videos on this channel regarding civil engg concepts are beyond appreciation.Just felt like I know something very great. Plz upload other concepts too.

[@spaceengineering6529]

go Waterloo...more than just Blackberry!!!

[@danko6582]

Sigh, I don't deserve a treat.

If you hold the beam at two points, you can ALWAYS hold it horizontally, making this example a lie, i.e. the woman is showing with her hands what she is supposed to, but she could just as well demonstrate the opposite! You should just support the beam at the one point (centre of mass). VERY BAD EXPLANATION therefore!

now we know why we must lean westward when walking west, and eastward when walking east. so simple!

[@rogerscottcathey]

. . . of course I'm kidding. duh.

Hello, will it be okay to use this video as a supporting media for my lecture?

[@g.sunilnaikg.sunilnai7996]

I enjoyed it

[@GrugFan]

wow.. no comments from around the time it was posted..

[@drew1998]

Who is the 1 dislike on this video

[@Bansheekilr]

Drew, it was the guy who clicked on it expecting to see another kind of body.

[@GrugFan]

Mario R lol

[@miguelpereira4639]

Please more Videos! Thks.

[@DenkiGroovu]

Awesome! More videos please!

[@abdulshahnawazkhan]

Love u guys.. Thanks

[@hariprasad900]

What a nice explanation!!!

[@RonakDhakan]

Where is the part 1?

[@echawia]

thank you so much

[@canaDavid1]

What if there is no "A"? How would you calculate that?

[@ImranZakhaev9]

If it is in equilibrium, the sum of moments will be 0 for ANY point. If it is NOT in equilibrium, the sum of moments will NOT be 0.

[@kallewirsch2263]

If an object is not somehow forced to rotate about a specific point A, it rotates about its center of gravity. Do if the question is just: is it in equilibrium? then the answer is: chose any point you like. If it is in equilibrium, then the moments cancel each other for all points. That includes the point you have chosen. If you need more, eg figure out how exactly the object will rotate and what momentum remains, then you have to calculate the center of gravity first. But this case is rare as usualy rotating bodies are not in free fall but are attached to some axis of rotation.

Great video

[@paw_lax.9021]

Hi! The material is awesome. Could you enable the contributions of the community so we can make the subs in another languages and make the knowledge get to more people? Thanks!
