- You can test this out yourself with a pencil or a ruler...
By supporting a rod from two points with your hands, a normal force is produced at each hand.
The hand which is supporting more of the weight of the rod will have a greater normal force, and therefore be able to withstand more static friction before sliding.
As a result the hand farthest from the rod will always slide toward the center of gravity of the rod, while the other hand remains static against the rod.
The end result is that your hands will always come together at the balance point of the rod.
Furthermore it does not matter if you add additional mass to one side of the rod and shift the balance point, there the hand supporting less weight will always be the hand to slide against the rod, and your hands will still come together at the balance point of the rod.
Great Video.... 👍👏🎉😁❤️❤️❤️
Please make More Such Videos....
So much to learn n educate the kids.... ❤️👍🎉👏
This is an awesome fun fact that has the potential to become very useful.
This kind of reminds me of finding the tangent line by moving the endpoints of the secant closer together
Would you mind elaborating please?
This is so cool
This is how that coin on bill trick works thank you for explaining
You're welcome.
...unless you have unequally sticky hands
it should be proportional to gravity acting on it , am i right brother?
say rod again
Mag liner hand truck and finding balance points is much easier than this, and requires only one person. I move commercial equipment and we come across 1, 2, and 3 door coolers/freezers
I would like to balance your rod

He was my physics teacher, he’s a nerd generator*

Can confirm
nice..
but
Now try the same experiment with a 40kg barbell
