Rollover Accident
A rollover is a type of vehicle crash in which a vehicle tips over onto its side or roof. Rollovers have a higher fatality rate than other types of vehicle collisions. Dynamics Vehicle rollovers are divided into two categories: tripped and untripped. Tripped rollovers are caused by forces from an external object, such as a curb or a collision with another vehicle. Untripped rollovers are the result of steering input, speed, and friction with the ground. Trailers that are not roll-coupled (i.e. those that use a trailer coupling rather than a fifth wheel) are more prone to rolling as they do not have the tractor unit or prime mover for additional stability. Untripped rollovers Untripped rollovers occur when cornering forces destabilize the vehicle. As a vehicle rounds a corner, three forces act on it: tire forces (the centripetal force), inertial effects (the centrifugal force), and gravity. The cornering forces from the tire push the vehicle towards the center of the curve. T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dynamic Rollover
A helicopter is susceptible to a rolling tendency, called dynamic rollover, when close to the ground, especially when taking off or landing. For dynamic rollover to occur, some factor has to first cause the helicopter to roll or pivot around a skid, or landing gear wheel, until its critical rollover angle is reached. Then, beyond this point, main rotor thrust continues the roll and recovery is impossible. If the critical rollover angle is exceeded, the helicopter rolls on its side regardless of the cyclic control corrections made. Dynamic rollover begins when the helicopter starts to pivot around its skid or wheel. This can occur for a variety of reasons, including the failure to remove a tiedown or skid securing device, or if the skid or wheel contacts a fixed object while hovering sideward, or if the gear is stuck in ice, soft asphalt, or mud. Dynamic rollover may also occur if the pilot does not use the proper landing or takeoff technique or while performing slope operations. Wh ...

Axle Track
In automobiles (and other wheeled vehicles which have two wheels on an axle), the axle track is the distance between the hub flanges on an axle. Wheel track, track width or simply track refers to the distance between the centerline of two wheels on the same axle. In the case of an axle with dual wheels, the centerline of the dual wheel assembly is used for the wheel track specification. Axle and wheel track are commonly measured in millimetres or inches. Common usage Despite their distinct definitions, ''axle track'', ''wheel track'' and ''track width'' are frequently used interchangeably, normally to refer to the distance between the centerline of the wheels. For a vehicle with two axles, the measurements can be expressed as ''front track'' and ''rear track''. For a vehicle with more than two axles, the axles are normally numbered for reference. Offset wheels In vehicles with offset wheels, wheel track is distinct from axle track because the centreline of the wheel is not flus ...

World Wide Tours Bus Crash
The World Wide Tours bus crash took place at about 5:30 a.m. on March 12, 2011, in the southbound lanes of the New England Thruway segment of Interstate 95 within Pelham Bay Park near Split Rock at the border between the Bronx and Pelham Manor, New York. The bus was returning to Chinatown, Manhattan, from the Mohegan Sun casino in Uncasville, Connecticut. It swerved and collided with a metal sign pole, which ripped through it and tore off most of its roof. Thirteen passengers died at the scene, two died at hospitals, and all seventeen others on board were injured. Cause Conditions of the crash Some surviving passengers have said that the driver, Ophadell Williams, fell asleep at the wheel. He was not charged initially, pending investigation. Williams said that he was awake and sober at the time of the accident. The bus driver blamed the accident on a tractor-trailer that he swerved to avoid, causing the bus to flip on its side and crash into an overhead highway sign which split t ...

Improvised Explosive Device
An improvised explosive device (IED) is a bomb constructed and deployed in ways other than in conventional military action. It may be constructed of conventional military explosives, such as an artillery shell, attached to a detonating mechanism. IEDs are commonly used as roadside bombs, or homemade bombs. IEDs are generally done in these terrorism operations or in asymmetric unconventional warfare by insurgent guerrillas or commando forces in a theatre of operations. In the Iraq War (2003–2011), insurgents used IEDs extensively against U.S.-led forces and, by the end of 2007, IEDs were responsible for approximately 63% of coalition deaths in Iraq. They were also used in Afghanistan by insurgent groups, and caused over 66% of coalition casualties in the 2001–2021 Afghanistan War. IEDs were also used frequently by the Liberation Tigers of Tamil Eelam (LTTE) in Sri Lanka during the Sri Lankan Civil War. Background An IED is a bomb fabricated in an improvised manner ...

Isuzu Trooper
The Isuzu Trooper is a full-size SUV that was produced by the Japanese automaker Isuzu between 1981 and 2007. In the domestic Japanese market it was sold as the Isuzu Bighorn, the car was exported internationally mainly as a Trooper but it also received several other nameplates including Acura SLX, Chevrolet Trooper, Subaru Bighorn, SsangYong Korando Family, Honda Horizon, Opel Monterey, Vauxhall Monterey, Holden Jackaroo, and Holden Monterey. In total, there were two generations of this vehicle: the first, produced between 1981 and 1991; and the second (UBS) produced between 1991 and 2007, with a substantial refresh in 1998. Production ended in 2007. The Trooper began as a rather basic and somewhat underpowered on- and off-road vehicle, offered only with four-cylinder motor, four-speed manual transmission, and part-time four-wheel drive. The first generation evolved to add both amenities and luxuries, including optional air-conditioning, power windows, and a more powerful V6 e ...

Jeep CJ
The Jeep CJ models are a series and a range of small, open-bodied off-road vehicles and compact pickup trucks, built and sold by several successive incarnations of the Jeep automobile marque from 1945 to 1986. The 1945 Willys Jeep was the world's first mass-produced civilian four-wheel drive car. In 1944, Willys-Overland, one of the two main manufacturers of the World War II military Jeep, built the first prototypes for a commercial version – the CJ, short for "civilian Jeep". From then on, all CJ Jeeps consistently had a separate body and frame, rigid live axles with leaf springs both front and rear, a tapering nose design with flared fenders, and a fold-flat windshield, and could be driven without doors. Also, with few exceptions, they had part-time four-wheel drive systems, with the choice of high and low gearing, and open bodies with removable hard or soft tops. After remaining in production through a range of model numbers, and several corporate parents, the Jeep CJ li ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ford E-Series
The Ford E-Series (also known as the Ford Econoline or Ford Club Wagon) is a range of full-size vans manufactured and marketed by the Ford Motor Company. Introduced for model year 1961 as the replacement for the Ford F-Series panel van, the E-Series line is currently in its fourth generation. Produced in multiple design variations for both retail and commercial sale, the E-Series was developed as a van for either cargo or passenger use, and as a cutaway van chassis and stripped chassis (a chassis without bodywork). Since the 2015 model year, only the latter two designs are offered, as Ford replaced E-Series vans with the Ford Transit. From 1980 to 2014, the E-Series van was the best-selling full-sized van in the United States. The model line entered its 60th year of production for 2021, thus being one of Ford's longest running model lines, second only to the Ford F-Series (in production since 1948) within Ford Motor Company.

Full-size Van
A van is a type of road vehicle used for transporting goods or people. Depending on the type of van, it can be bigger or smaller than a pickup truck and SUV, and bigger than a common car. There is some varying in the scope of the word across the different English-speaking countries. The smallest vans, microvans, are used for transporting either goods or people in tiny quantities. Mini MPVs, compact MPVs, and MPVs are all small vans usually used for transporting people in small quantities. Larger vans with passenger seats are used for institutional purposes, such as transporting students. Larger vans with only front seats are often used for business purposes, to carry goods and equipment. Specially-equipped vans are used by television stations as mobile studios. Postal services and courier companies use large step vans to deliver packages. Word origin and usage Van meaning a type of vehicle arose as a contraction of the word caravan.

Sport Utility Vehicle
A sport utility vehicle (SUV) is a car classification that combines elements of road-going passenger cars with features from off-road vehicles, such as raised ground clearance and four-wheel drive. There is no commonly agreed-upon definition of an SUV and usage of the term varies between countries. Thus, it is "a loose term that traditionally covers a broad range of vehicles with four-wheel drive." Some definitions claim that an SUV must be built on a light truck chassis; however, broader definitions consider any vehicle with off-road design features to be an SUV. A crossover SUV is often defined as an SUV built with a unibody construction (as with passenger cars), however, the designations are increasingly blurred because of the capabilities of the vehicles, the labelling by marketers, and electrification of new models. The predecessors to SUVs date back to military and low-volume models from the late 1930s, and the four-wheel drive station wagons and carryalls that began ...
