Diagram showing the path of a driver performing a U-turn.A vehicle with a smaller turning diameter will be able to perform a sharper U-turn. The turning radius (alternatively, turning diameter or turning circle) of a vehicle defines the minimum dimension (typically the radius or diameter) of available space required for that vehicle to make a semi-circular U-turn without skidding.
U.S. submarines during World War II preferred to fire their torpedoes at small gyro angles because the TDC's fire control solutions were most accurate for small angles. [ 43 ] The problem of computing the gyro angle setting is a trigonometry problem that is simplified by first considering the calculation of the deflection angle, which ignores ...
Engineering drawing abbreviations and symbols are used to communicate and detail the characteristics of an engineering drawing. This list includes abbreviations common to the vocabulary of people who work with engineering drawings in the manufacture and inspection of parts and assemblies.
In order to decrease their turning radius, all four of the 8x8 wheeled unit's front wheels may be steerable. Newer airport crash tenders also incorporate twin-agent nozzles/injection systems to inject a stream of Purple-K dry chemical into the AFFF firefighting foam stream, helping to extinguish the fire faster.

Steering could have up to a 45 cut, allowing very tight turning radius. Single rear axles rated at 18,500 pounds (8,400 kg) were used in small MC models, but most were 23,000 pounds (10,000 kg) and later MR models could be up to 30,000 pounds (14,000 kg). The Camelback tandem is the base rear suspension. The Camelback has multiple leaves that ...
A short piece of fire hose, usually 10 to 20 feet (6.1 m) long, of large diameter, greater than 2.5 inches (64 mm) and as large as 6 inches (150 mm), used to move water from a fire hydrant to the fire engine, when the fire apparatus is parked close to the hydrant. Solid stream A fire-fighting water stream emitted from a smooth-bore nozzle.
The yaw rate is directly related to the lateral acceleration of the vehicle turning at constant speed around a constant radius, by the relationship tangential speed*yaw velocity = lateral acceleration = tangential speed^2/radius of turn, in appropriate units. The sign convention can be established by rigorous attention to coordinate systems.
A fire engine or fire truck (also spelled firetruck) is a vehicle, usually a specially-designed or modified truck, that functions as a firefighting apparatus. The primary purposes of a fire engine include transporting firefighters and water to an incident as well as carrying equipment for firefighting operations in a fire drill .
