What happens when you spin a CD too fast? The answer is that it shatters.... The guys claim the critical spin rate for a CD is 23,000 rpm. Let’s see if. If you are listening to music on your record player, the chances are that you are looking at a full-size 12-inch vinyl, and It must be spinning at 33-1/3 RPM. The second most popular is a 7-inch single that spins at 45 RPM. Many times artists use 12-inch records for producing EPs / full albums and 7-inch for singles.
Approximately how fast do disks, CDs DVDs etc. spin? - Houzz.
Several companies have made the maximum speed CD-Writing standard 48x (see article) instead of 52X or higher due to the fact that at 52x the CD is spinning at 10 000RPM and several CDs have been known to explode at those speeds, destroying the drive and some times sending pieces out from the CD tray. The fastest drivers on the market today.

Suppose a piece of dust finds itself on a CD. If the spin rate of the CD is 500 rpm, and the piece of dust is 4.3 cm from the center, what is the total distance traveled by the dust in 3 minutes?

Solved How much torque is required to spin up a CD from rest.
The rotational speed, or angular velocity, of a DVD goes between 570-1600 rpm (rotations per minute). The closer to the center of the disc, the faster it spins and which is why there is a range for the angular velocity and not one specific number. This means the "read head" passes the same length at all times and radii. The average golf ball spin rate is 2686 rotations per minute (rpm) when using a driver. A 3-wood has a spin rate of 3655rpm, where a 5-wood is measured at 4350rpm. Ahybrid club with a loft angle between 15 and 18° has an average spin rate of 4437rpm. A 3-iron club has an average spin rate of 4630rpm. A 4-iron club which has a higher loft angle. It’s like riding a bike—literally. Spinning® movements correspond to moves you would do on a road bike. There are five core movements with corresponding hand positions to position you in optimal riding posture. The five core movements of the Spinning program are as follows: Seated Flat – Hand Position 1,2 or 2.5 Seated Climb – Hand Position 2 or 2.5 Standing Flat – Hand.

Over 10 years later, commonly available drives vary between 24× (slimline and portable units, 10× spin speed) and 52× (typically CD- and read-only units, 21× spin speed), all using CAV to achieve their claimed "max" speeds, with 32× through 48× most common. Anonymous Coward writes: "Ever wonder why cd-rom/cd-rw drives are not getting any faster? Wonder why they heat up? This page has a rather amusing experiment where they put various CD's into something that can spin up to 30,000RPM and found that most cd's explode at just around 28,000RPM. Using the formula, this is simple to calculate. Assuming the same MV of 3000 FPS, the bullet makes 12/8 or 1.5 revolutions for each 12″ or one foot it travels in the bore. Accordingly, the RPM is 3000 x (12/8) x 60, or 270,000 RPM. Calculating the RPM based on twist rate and MV gives us some very important information.
High Speed Bearing Spinning (80,000+ Rpm) ! - YouTube.
Usually, the drive shaft turns faster than the hubs of the driven wheels. Now that you have the RPM of the drive shaft, you use the transmission ratios to determine the engine RPM, which is the.
Linear & Angular Speed of a CD - The Physics Factbook.
( A, Amazon UK) The first CD started ripping at about 5x, and ended around 10x. (The first CD drives could read data at 150 kb/sec; this is 1x. Read and write speeds, for CDs, use multiples of that original speed.) Yet yesterday, I was ripping some other CDs, and they started at around 10x, finishing at 24x. Why this difference?. CDs spin at an angular speed of 500 rpm when read from the center and 200 rpm when read near the circumference. Besides having an angular velocity, the CD also has a constant linear velocity (CLV). The CLV of a CD has been standardized by Philips at 1.2 to 1.4 m/s. CDs are much more efficient than black records. A standard 12-inch 33 RPM vinyl record can have a playtime of roughly 22 minutes per side for a total of 44 minutes. A 7-inch 45 RPM record can fit approximately 5 minutes per side for a total of 10 minutes. Generally, any longer, the sound quality would start to deteriorate. These are the two most common types of records and covers a majority.
How many rpm does a cd spin at.
33, 45, and 78 RPM is the speed at which the most common commercially available vinyl records spin at represented in revolutions per minute. The records themselves are often referred to by their speed. As an example, a 7" single featuring a single song is often referred to simply as "a 45", or a shellac disc is often called a "78". Answer (1 of 2): The diameter of the CD is 12cm. So the circumference is π x 12 which is 37.7cm which is 0.377 metres multiply by 1080 - gives 407 metres per minute. Converting this into other measurements that’s 6.8 metres per second, 24.4 km/h, or.

Subscribe! T-shirts & Hoodies! stupid but a lot of fun!Support my videos!:. Answer (1 of 3): It spins slower at the outside and faster in the middle — this is to allow the data to be read at a constant speed — as if it was on one long straight ribbon. The data is read at around 150 kilobits/sec. 8-Twist RPM = 2800 x (12/8) x 60 = 252,000 RPM MV = 3200 FPS 9-Twist RPM = 3200 x (12/9) x 60 = 256,000 RPM Of course max velocity will be limited by case capacity and pressure. You can't switch to a slower twist-rate barrel and maintain RPM if you've already maxed out your MV.

Next click on the Device Manager link on the left. You can also just open Control Panel and click on Device Manager from there. Now expand Disk drives and you should see the model number of your hard drive, like shown below. On my computer, it shows the entire model number of the hard drive (Hitachi HTS54…), which makes it really easy to look up. CD-ROM average seek times range from 200 milliseconds (ms) to as low as 80ms. In comparison, current hard drive seek times are typically around 9ms, and some are lower. The fastest drives use Constant Angular Velocity (CAV) technology. CD-ROM drives usually operate using Constant Linear Velocity (CLV). Woodworker's Journal 25 Jigs and Fixtures, CD. $14.99.

It depends on which track you are listening to. Since CD's are read from the inside out, as disc spins significantly faster on the first few tracks, around 460 RPM (Rotations per minute). Towards the end of the disc, it doesn't have to spin as fast to read the same ammount of information, and would spin around 200 RPM.
Vinyl Record Sizes - What does 33, 45, and 78 RPM Mean?.
On many kinds of disc recording media, the rotational speed of the medium under the read head is a standard given in rpm. Phonograph (gramophone) records, for example, typically rotate steadily at 16 + 2 ⁄ 3, 33 + 1 ⁄ 3, 45 or 78 rpm (0.28, 0.55, 0.75, or 1.3 Hz respectively).
RECORD SIZES WITH THEIR SPEEDS.
As you finish listening to your favorite compact disc (CD), the CD in the player slows down to a stop. Assume that the CD spins down with a constant angular acceleration Q = 20.1 rad/s Submit Previous Answers Correct Part B How many revolutions does the CD make as it spins to a stop?

Vinyl Record Sizes and Speeds - What does 33 - 45- 78 RPM means?.
Considering how small the bumps are, the CD player is an exceptionally precise piece of equipment. The drive consists of three fundamental components: A drive motor spins the disc. This drive motor is precisely controlled to rotate between 200 and 500 rpm depending on which track is being read. Science Explains Why CDs Shatter Upon Spinning too Fast. The CD shattering at more than 76,000 frames per second. The Slow Mo Guys / YouTube. You might not expect this, since CDs and DVDs are made. A CD rotates at 500 (revolutions per minute) while the last song is playing, and then spins down to zero angular speed in 2.60 seconds with constant angular acceleration. The magnitude of the angular acceleration of the CD, as it spins to a stop is 20.1 radians per second squared.
