Rolling Ball
What’s the music video called with the rolling ball?
The whole video the ball goes on this crazy, animated adventure with tons of really trippy background changes. Anyone know what I’m talking about?
There are 3 different things you can do to try and find a
video that you have previously viewed. Even better, you
can have those results appear either: 1) in alphabetical
order, 2) in chronological order or 3) in photo thumbnail
form:
ALPHABETICALLY (tons of results):
highlight the URL address bar on top, then simply type
in the word “youtube”. From those results, you will see:
– every YouTube address you typed
– every YouTube channel you visited
– every YouTube video you watched
but it will be ugly YouTube code like “v=Ab1Cd2eF3Gh”.
CHRONOLOGICALLY (many results):
simply click on your internet browser’s ”History” button
or tap “CTRL” and the letter “H” on your keyboard, and
you will get a daily list of every website which you have
visited. Every YouTube video will be mixed in with all of
the different websites, but it’ll actually be easier for you
to locate that particular video — because everything will
be displayed in ”plain” English. And because each and
every YouTube video is in fact its own website, you will
also be able to see the full title of each video.
PHOTO THUMBNAIL (few results):
when you’re “signed-in” on YouTube, the top right of all
YouTube pages display your “username” in a rectangle.
Click on that, and then “Favorites”. On the left side will
be “History”, (3 lines below the grayed Favorites). Click
on that, and you’ll thus see thumbnails of all the recent
videos you’ve watched — but only the most recent ones.
The reason for that is because everytime you open/exit
YouTube, your history is cleared, and starts over again.
Believe it or not, you can actually check your YouTube
viewing history from right here in Yahoo! Answers. Just
click on my links below, and they’ll take you directly to
”YOUR VERY OWN” histories. (YouTube may first ask
you to ‘sign in’ with your username and your password):

I hope that my multiple answer is a little helpful for you.

What Shape Are Ball Bearings?
It may sound like an obvious question as you would think that ball bearings are ball shaped. To see the shape of a ball bearing lets first look at how they are made. It may be surprising but they actually start with a piece of thick wire. Using a process called Cold Heating, the wire is then cut of at both ends, via a machine, until it is a small piece, hence the name the wire is not heated during this process. The machine has a cavity the shape of a hemisphere on each side and slams into the wire to make the shape of a ball. This process leaves a flash around a ball, which is a piece of metal around the ball making it look a bit like the planet Saturn. The balls are then fed into a machine that rolls the flash away leaving a very smooth and very perfect shaped ball.
So the answer to ‘what shape is a ball bearing?’ is a ball shape right? Well yes and no, this part of the ball bearing is a ball that is correct but this is not entirely a ball bearing, you can’t put a ball into a machine and expect it to work, it needs other parts to the ball bearing for the bearing to operate. So what shape are the other parts to a ball bearing I hear you ask. The shape of the other parts to a ball bearing depends on the type of ball bearing because there are several different designs.
What parts make up the shape of a ball bearing?
Typically within a ball bearing several components are used including an outer ring, an inner ring, a cage or a retainer inside, and the balls. All of this makes up the whole of a ball bearing, but because the rolling element inside the bearing are balls it is called a ball bearing but the shape of it is more a hula shape like a wheel, but they probably would not have wanted to have called it a hula bearing for obvious reasons!
How are these parts assembled to make a ball bearing?
First you take the inner race and place into the outer race placing it to one side as far as possible. Place the balls between the two races, the amount of balls you place depends on the size of the races and the type of bearing. Once the balls are in place the races are moved into the centre. The cage is installed to keep the races and balls in place. Rust and protective coats are placed over the bearing and then sealed. And hey presto that is how you make a ball bearing.
