MythBusters (2009 Season)
The cast of the television series ''MythBusters'' perform experiments to verify or debunk urban legends, old wives' tales, and the like. This is a list of the various myths tested on the show as well as the results of the experiments (the myth is MythBusters#Outcomes of the experiments, Busted, Plausible, or Confirmed). Episode overview Episode 114 – "Demolition Derby" * Original air date: April 8, 2009 This episode was an 87-minute-long special. The vehicles that were demolished during the episode all received an end credit in the form of an ''wikt:in memoriam, in memoriam'' (spelled ''wikt:in memorium, in memorium'' on screen). Need for Speed Hollywood Crash Test Based on numerous car chase scenes in films, the Build Team tested myths based on whether cars would be able to successfully drive through/into various obstructions. Two criteria were used to test each scenario: whether the real crash appeared similar to its Hollywood counterpart, and whether the car could be dri ...

Wanted (2008 Film)
''Wanted'' is a 2008 action thriller film directed by Timur Bekmambetov and written by Michael Brandt, Derek Haas, and Chris Morgan, loosely based on the comic book miniseries by Mark Millar and J. G. Jones. The film stars James McAvoy, Morgan Freeman, Angelina Jolie, Terence Stamp, Thomas Kretschmann, Common, and Chris Pratt. Its plot revolves around Wesley Gibson (McAvoy), a frustrated account manager who discovers that he is the son of a professional assassin and decides to join the Fraternity, a secret society in which his father worked. Universal Pictures acquired the adaptation rights from Millar in 2004, and while the eventual script drifted from the comic book supervillain mythos in the original miniseries, he was content to see most of the comic's darker content retained. Production began in April 2007, with filming in the Czech Republic, Budapest, and the story's main setting, Chicago. Bekmambetov's production company, Bazelevs Production, provided the majorit ...

Explosion Welding
Explosion welding (EXW) is a solid state (solid-phase) process where welding is accomplished by accelerating one of the components at extremely high velocity through the use of chemical explosives. This process is often used to clad carbon steel or aluminium plate with a thin layer of a harder or more corrosion-resistant material (e.g., stainless steel, nickel alloy, titanium, or zirconium). Due to the nature of this process, producible geometries are very limited. Typical geometries produced include plates, tubing and tube sheets. Development Unlike other forms of welding such as arc welding (which was developed in the late 19th century), explosion welding was developed relatively recently, in the decades after World War II. Its origins, however, go back to World War I, when it was observed that pieces of shrapnel sticking to armor plating were not only embedding themselves, but were actually being welded to the metal. Since the extreme heat involved in other forms of welding ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rocket Sled
A rocket (from it, rocchetto, , bobbin/spool) is a vehicle that uses jet propulsion to accelerate without using the surrounding air. A rocket engine produces thrust by reaction to exhaust expelled at high speed. Rocket engines work entirely from propellant carried within the vehicle; therefore a rocket can fly in the vacuum of space. Rockets work more efficiently in a vacuum and incur a loss of thrust due to the opposing pressure of the atmosphere. Multistage rockets are capable of attaining escape velocity from Earth and therefore can achieve unlimited maximum altitude. Compared with airbreathing engines, rockets are lightweight and powerful and capable of generating large accelerations. To control their flight, rockets rely on momentum, airfoils, auxiliary reaction engines, gimballed thrust, momentum wheels, deflection of the exhaust stream, propellant flow, spin, or gravity. Rockets for military and recreational uses date back to at least 13th-century China. Significant ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Terminal Velocity
Terminal velocity is the maximum velocity (speed) attainable by an object as it falls through a fluid (air is the most common example). It occurs when the sum of the drag force (''Fd'') and the buoyancy is equal to the downward force of gravity (''FG'') acting on the object. Since the net force on the object is zero, the object has zero acceleration. In fluid dynamics an object is moving at its terminal velocity if its speed is constant due to the restraining force exerted by the fluid through which it is moving. As the speed of an object increases, so does the drag force acting on it, which also depends on the substance it is passing through (for example air or water). At some speed, the drag or force of resistance will equal the gravitational pull on the object (buoyancy is considered below). At this point the object stops accelerating and continues falling at a constant speed called the terminal velocity (also called settling velocity). An object moving downward faster than ...

Airbag
An airbag is a vehicle occupant-restraint system using a bag designed to inflate extremely quickly, then quickly deflate during a collision. It consists of the airbag cushion, a flexible fabric bag, an inflation module, and an impact sensor. The purpose of the airbag is to provide a vehicle occupant with soft cushioning and restraint during a collision. It can reduce injuries between the flailing occupant and the interior of the vehicle. The airbag provides an energy-absorbing surface between the vehicle's occupants and a steering wheel, instrument panel, body pillar, headliner, and windshield. Modern vehicles may contain up to 10 airbag modules in various configurations, including: driver, passenger, side-curtain, seat-mounted, door-mounted, B and C-pillar mounted side-impact, knee bolster, inflatable seat belt, and pedestrian airbag modules. During a crash, the vehicle's crash sensors provide crucial information to the airbag electronic controller unit (ECU), including colli ...

Speed (1994 Film)
''Speed'' is a 1994 American action thriller film directed by Jan de Bont in his feature film directorial debut. The film stars Keanu Reeves, Dennis Hopper, Sandra Bullock, Joe Morton, and Jeff Daniels.

Antacid
An antacid is a substance which neutralizes stomach acidity and is used to relieve heartburn, indigestion or an upset stomach. Some antacids have been used in the treatment of constipation and diarrhea. Marketed antacids contain salts of aluminum, calcium, magnesium, or sodium. Some preparations contain a combination of two salts, such as magnesium carbonate and aluminium hydroxide (e.g. hydrotalcite). Medical uses Antacids are available over the counter and are taken by mouth to quickly relieve occasional heartburn, the major symptom of gastroesophageal reflux disease and indigestion. Treatment with antacids alone is symptomatic and only justified for minor symptoms.U.S. Department of Health & Human Services. Agency for Healthcare Research and Quality 23 September 201Consumer Summary – Treatment Options for GERD or Acid Reflux Disease: A Review of the Research for Adults Alternative uses for antacids include constipation, diarrhea, hyperphosphatemia, and urinary alkalizatio ...
