No-Rules NASCAR - xkcd.

Well, correct me if I'm wrong anybody, but the force in action here is torque. Accelerate rotation you get turn, decelerate you get fade on a rotating disc. So..... Less spin means less fade (and likely less glide).... It will fly straight while it's spinning fast, and seems to have a high stall speed (meaning it'll fade and drop fairly.

NASA's Rocket-Powered Saucer Set for Launch - Popular Mechanics.

Moment of Inertia of a disc is (mass * r 2) / 2. Angular acceleration, how quickly the disc changes speed, is up to you to decide. Torque required = Angular Acceleration * Moment of Inertia. MarkT July 7, 2015, 9:49pm #4. If the wheel is well balanced with quality bearings you won't need much torque, as you'll. Nipkow disk-based spinning disk confocal microscopes offer an excellent alternative for fast scanning of living specimens. These instruments are based on a circular, rotating disk that contains one or more pinhole arrays that are arranged in an Archimedean spiral designed to scan the entire specimen plane during a single disk rotation (or less with some designs). In effect, this is a giant centrifuge. This lets us apply one of my favorite weird equations, [4] See footnote [8] in article #86. which says that the edge of a spinning disc can't go faster than the square root of the specific strength [5] (tensile strength divided by density) of the material it's made of. For strong materials like Kevlar.

What determines how fast a weapon is able to spin up?.

Clutch control refers to the act of controlling the speed of a vehicle with a manual transmission by partially engaging the clutch plate, using the clutch pedal instead of (or in conjunction with) the accelerator pedal. The purpose of a clutch is in part to allow such control; in particular, a clutch provides transfer of torque between shafts spinning at different speeds. First, you need to express angular velocity in radians per second, not revolutions per second. You know that the initial angular velocity is 700 revolutions per second, so in terms of radians per second, you get Similarly, you can get the final angular velocity this way. In principle it's easy to make a spiral arm. For various reasons, stuff in the disk sometimes clumps together, but the clump won't stay a clump for long: stars and clouds near the galactic center circle the galaxy faster than the material farther out does, so over time the clump gets stretched into a spiral.

We develop an extension of fluorescence correlation spectroscopy (FCS) using a spinning disk confocal microscope. This approach can spatially map diffusion coefficients or flow velocities at up to ∼10 5 independent locations simultaneously. Commercially available cameras with frame rates of 1000 Hz allow FCS measurements of systems with diffusion coefficients D∼10 −7 cm 2 /s or smaller. The Physics Of Curling. Curling stones are thick stone disks made of heavy, polished granite, with a handle attached to the top (shown in the picture below). Curling regulations state that the maximum mass of a curling stone is 20 kilograms. The typical mass of a curling stone lies between 17 and 20 kg. Have you program demand exclusive control over the disk resource and the processors. Block all other unimportant tasks; raise the priority of your program's execution. Use multiple buffers to keep the disk drive spinning. A large portion of time is spent waiting for the hard drive to accelerate and decelerate.

A question about braking and deceleration of an AC motor.

Using interrupts to avoid spinning. CPU: Disk: A AA. B. C. A. 1 3,4. 2. B. B. Interrupts vs. Polling... Hard Disk Basic Interface. Disk has a sector-addressable address space(so a disk is like an array of sectors).... Build fast, large disk from smaller ones. Add even more disks for reliability. Disk. A new method of using centrifugal force to decelerate particles makes it possible to produce relatively large quantities of cold molecules in a continuous flow, which could create new opportunities for chemistry and quantum information processing. Compared with our breath, passenger planes move at a pretty leisurely pace.

Palm sander spins too fast - Power Tools - Tools in Action.

In virtually all good putting strokes, the ball is hit with a slight positive angle of attack (AoA) - about 2-3° or so. This positive AoA helps minimize backspin, produce no spin, or even to produce a tiny bit of forward spin if the dynamic loft is 1-2°. But the point is: the ball is struck while the putter head is ascending, or after low point. But, I have seen quite a few sources cite that inertia is the reason why the earth keeps spinning. 1. Veritasium. 2. Universe Today. The Earth spins because it formed in the accretion disk of a cloud of hydrogen that collapsed down from mutual gravity and needed to conserve its angular momentum. It continues to spin because of inertia.

Motor Type and Torque Needed to Spin This Wheel. - Arduino Forum.

Basics of Disc Brakes. Disc brakes are found on most vehicles today. They are mounted on the front and/or rear axle. To stop a wheel (and your car), a disc brake uses a caliper fitted with brake pads to grab a spinning disc or rotor. What is a caliper? The caliper is an assembly mounted to the vehicle with a bracket. It frames the rotor. Disk drive employing method of spinning down its spindle motor to reduce the time required for spinning it down and subsequently spinning it up: A disk drive employs... of the windings to generate a negative torque on the rotor such that a controlled braking operation is performed to decelerate the rotor to a selected spin-rate After. Problem 6. The Crab Nebula One of the most studied objects in the night sky. is the Crab nebula, the remains of a supernova explosion observed. by the Chinese in In 1968 it was discovered that a pulsar-a rapidly rotating neutron star that emits a pulse of radio waves. with each revolution-lies near the center of the Crab nebula.

Thankfully there are a few simple things that can help distinguish between rear differential noise and wheel bearing noise. Wheel Bearing Noise. Simplest check to identify a failing wheel bearing is to suspend the car so that the wheel does not touch the ground. Then grab the wheel and wiggle it back & forth.

Definition of spin down in the Idioms Dictionary. spin down phrase. What does spin down expression mean?... To decelerate (to some speed or state) while spinning.... The computer automatically spins down the disk drive in order to conserve power when it no longer needs to read or write data. 4. To spin some solution in a centrifuge in order. First, press the power button on your watch to open the apps panel. Then select 'Samsung Health' app from the list. In the Samsung Health application interface that appears, scroll down to the heart rate measurement section and click on it. Now, just press the "Measure" button and the heart rate measurement on the watch will take place. A simple and fast manual centrifuge was developed to spin down solutions in 96-well polymerase chain reaction (PCR) plates. A commercially available salad spinner was utilized for this purpose.

Does the Earth keep spinning because of inertia? - Physics Stack Exchange.

How Fast do Helicopter Blades Spin? The blades on small helicopters spin between 400 and 500 revs per minute (RPM). Rotor blades on large helicopters spin at a slightly slower rate of around 230+ RPM. For example, the Chinook C-47 Army helicopter blades spin at 225 RPM, while a Robinson R22 Beta light helicopter blades spin at 530 RPM. The rotational speed typically 5400, 7200, 10000 rpm indicates how fast the disk spins. A read/write head that picks up the 1's and 0's written on the disk runs over these tracks. Obviously, with the increased speed, the head can then read the bits faster. So, when you read from a disk, the 7200 rpm will read faster than the 5400 rpm. Matthew Leib. Inspired by various applications (ocean's renewable power technologies, spinning disc reactor, engineering systems, etc.) of fluid flow between rotating disc, we have investigated magnetohydrodynamic flow of multi-wall and single-wall carbon nanotubes (MWCNTs and SWCNTs)-based fluid between two rotating, coaxial and parallel stretching discs with porous medium and convective thermal.

Do not pull the disc fast when you are in your backswing. Pull in the disc gradually till it reaches your chest, and then rotate your hips and blast off your arm through the air. For maximum effort, don't forget to follow through with your throw. Select The Appropriate Disc Start playing by selecting the appropriate disc.

I'm quite certain that the spin will decrease over time due to parasitic drag. If the air speed of the disc increases after release due to head wind or gravity when thrown down hill the disc will go into/ increase it's high speed turn mode. Birdie Apr 12 2008, 11:09 PM I am no authority by an means, but I have had some physics in high school.

PDF PERSISTENCE: DISK SCHEDULING - University of Wisconsin-Madison.

A speed 13 disc needs a very fast arm speed where a speed 9 disc can have an effective flight pattern with less arm speed required. Faster speed discs are less likely to "turn over" in their flight pattern where that 9 speed, if thrown by a monster arm, can turn easier in the air and finish farther right than intended. Spinning disk confocal microscopy (SDCM) is a widely-used extension of confocal LSM that allows for higher imaging speeds (8,9). (The speed limitation in the most common LSM implementation results from the time needed to repeatedly accelerate and decelerate the scanning mirror, which is eliminated in SDCM.).

Understanding and Diagnosing Rear Differential Noise.

For fast deceleration, the fluid always flows away from the disk. Fast deceleration leads to more fluid pushed away from the disk, which is opposite to the suction effect of the rotating disk. The circumferential velocity can be negative with rotation in the opposite direction of the disk at a sufficiently large distance from the disk. There are a lot of factors that determine spin up. Your weapons moment of inertia, ( put simply, basically how much power your weapon can have at a speed.)The weight of the weapon affects MOI thus effects spin up speed. The motors torque, is one of the biggest factors. And friction isn't a huge factor, but it can become a problem if not considered.
