Target-type thrust reversal (also called bucket thrust reversal or clamshell thrust reversal [1]) is a deceleration method when an aircraft lands. Like other types of thrust reversals, it temporarily diverts the engine exhaust forward to provide deceleration. This type of thrust-reverser is suitable for engines of 3,000 lbf (13 kN) or greater ...
It may also be advantageous to switch it off if engine braking is desired, for example when driving downhill. The vehicle's owner's manual will often contain information and suitable procedures regarding such situations, for each given vehicle. Virtually all vehicles (cars and trucks) have overdrive today whether manual transmission or automatic.
A semi bottom dump, bottom hopper, or belly dump is a (commonly) 3-axle tractor pulling a 2-axle trailer with a clam shell type dump gate in the belly of the trailer. The key advantage of a semi bottom dump is its ability to lay material in a windrow, a linear heap. In addition, a semi bottom dump is maneuverable in reverse, unlike the double ...

A properly equipped C-Series half-ton class pickup could tow up to 8,000 lbs (4 tons) of braked trailer, while a properly equipped C-Series three-quarter-ton or one-ton class pickup could tow up to 12,000 lbs (6 tons) of braked trailer. [37] Adding four-wheel drive reduced towing capability due to increased curb weight, which resulted from ...

A drive shaft system weighs more than a chain system, usually 0.5–1 kg (1–2 lb) heavier. Many of the advantages claimed by drive shaft's proponents can be achieved on a chain-driven bicycle, such as covering the chain and sprockets. Use of lightweight derailleur gears with a high number of ratios is impossible, although hub gears can be used.
A two-wheel drive vehicle has two driven wheels, typically both at the front or back, while a four-wheel drive has four. A steering wheel is a wheel that turns to change the direction of a vehicle. A trailer wheel is one that is neither a drive wheel, nor a steer wheel. Front-wheel drive vehicles typically have the rear wheels as trailer wheels.
