unusual facts about vibration


Pitch of brass instruments

The pitch of a brass instrument is determined by the fundamental frequency and frequencies of its overtones for each vibratory length achievable through the instrument's valve, slide, key or crook system.


Alphabet für Liège

These ideas were developed in conversations with the British biophysicist and lecturer on mystical aspects of sound vibration Jill Purce, who also called Stockhausen's attention to the work of Hans Jenny (Kurtz 1992, 192–93; Jenny 1967).

Ann Dowling

Professor Dame Ann Patricia Dowling, DBE, FRS, FREng (born 15 July 1952) is a British mechanical engineer who researches combustion, acoustics and vibration, focusing on efficient, low-emission combustion and reduced road vehicle and aircraft noise.

Approach and Landing Tests

These tests first saw Enterprise taken to the Dynamic Structural Test Facility in Alabama, where the complete stack subjected to vertical ground vibration tests, assessing the structural responses to a number of scenarios.

Basic physics of the violin

Excitation of string vibration is generally provided by a bow consisting of a flat ribbon of parallel horse hairs stretched between the ends of a stick, which may be made of wood or synthetic material such as fiberglass or carbon-fiber composite.

BonNova

The BonNova rocket team for the Lunar Lander Challenge was led by their chief engineer, Allen Newcomb, a rocket engineer with a career background of combined experience in avionics and design for extreme environments that can expose equipment to extreme heat such as oil wells, and race cars with brutal vibrations and extreme EMI

Bristol S.S.A.

The sole prototype, given the serial 'No.219', was first flown at Larkhill on 8 May 1914 with a temporary aluminium spinner due to vibration with the steel assembly.

Chelosin

On September 25, 1911, the ship was taken out for its first trial run on Belfast Lough, and a speed of 14 knots was recorded over the measured mile with no vibration.

Cotter pin

Bowtie cotter pin, a vibration-proof type of R-clip that is shaped like a bowtie

Crossplane

The 2009 Yamaha YZF-R1 motorcycle uses the crossplane crankshaft and, in the absence of the 90° bank angle of the V8, must use a separate balance shaft geared off the crankshaft to eliminate the inherent rocking vibration (primary rocking couples) found in this type of crank.

Engine balance

In a V-twin with a shared crank pin (e.g. Ducati 'L-twin'), the strong vibration of the 360°-crank parallel twin is divided into two different directions and phase separated by the same amount of degrees as in the V angle, with 13. unevenly spaced firing as well as the imbalances 4., 6., 14. and 16.

Eurocopter EC155

Other major improvements include a five-blade Spheriflex composite main rotor combined with the familiar shrouded Fenestron tail rotor to reduce vibration levels significantly.

Harmonic damper

Both Frederick Henry Royce and Frederick W. Lanchester have strong claims to the invention of the vibration damper, with the latest research showing Rolls-Royce using a crankshaft slipper (friction) vibration damper on their 1906 30HP models, however Royce had not submitted it for patent.

Hiroyoshi Tenzan

Tenzan appeared in the video for "Yonaoshi Good Vibration" by Japanese metal band Sex Machineguns.

Immersion v. Sony

In 2002, Sony and Microsoft were sued by Immersion for patent infringement for the use of vibration functions in their gaming controllers.

Morley Bartnoff

His original track "For... The Time Being," from the Cosmo Topper CD Pure Fast Vibration, is heard during the end credits of Mayor of the Sunset Strip, a rock documentary examining the life and career of legendary KROQ-FM DJ Rodney "On the 'ROQ" Bingenheimer, produced by Dramarama's Chris Carter.

Nociception

The gate control theory of pain, proposed by Patrick David Wall and Ronald Melzack, postulates that nociception (pain) is "gated" by non-nociception stimuli such as vibration.

Ongoing reliability test

highly accelerated stress test is a Ongoing Reliability Test that uses the empirical operational limits as the reference for the combined vibration, thermal cycling, and other stress applied to find latent defects.

Palandomus

The Palandomus invented in 1919 by architect Mario Palanti, consists of a cementblock of 18x18x36cm made with the vibration system, to serve as the cellular element of construction, being designed with a particular shape "hermaphrodite", which allows placement in any sense, without the constraints of location if not horizontal.

Quantum clock

Both the aluminum-based quantum clock and the mercury-based atomic clock keep track of time from the ion vibration at an optical frequency by using a UV laser, that is 100,000 times higher than the microwave frequencies used in NIST-F1 and other similar time standards around the world.

Shape theory of olfaction

A study by Leslie B. Vosshall and Andreas Keller, published in Nature Neuroscience in 2004, tested several key predictions of the competing vibration theory and found no experimental support for it.

Shenzhou 7

Special attention has been paid to solving vibration problems that were encountered 120 seconds into the Shenzhou 5 mission.

Standard J

Though the J-1 and its variants were produced in large numbers, it was disliked by instructors and students alike because of its highly vibration-inducing and unreliable four-cylinder Hall-Scott A-7a engine.

Star Wars Episode I: Racer

The Game Boy Color version of the game had an additional "Rumble" feature, in which you could put an AAA battery into the game card to activate vibration.

Steve Grissom

He started 43rd after crashing in qualifying and finished 43rd in the race after a vibration in car on lap 2.In 2005, Grissom joined with Jay Robinson Racing to drive the #49 Advil Ford Taurus.

Vibrations of a circular membrane

The vibrations of an idealized circular drum head—essentially an elastic membrane of uniform thickness attached to a rigid circular frame—are solutions of the wave equation with zero boundary conditions.

Vincent Ford

Ford was given writing credit for "No Woman, No Cry" on the 1974 album Natty Dread, as well the songs "Crazy Baldhead" (with Marley's wife Rita), "Positive Vibration" and "Roots Rock Reggae" from the 1976 album Rastaman Vibration, along with "Inna De Red" and "Jah Bless" with Marley's son, Stephen.

Zytronic

As a result the touch display can be completely protected from external factors and has a far greater resistance to rough treatment of all forms – abrasion, shock, vibration, extreme heat levels, adverse weather conditions and exposure to harmful chemicals in contrast with other traditional touch sensing techniques, such as optical, acoustic, capacitive, infra-red or resistive screens.
