The U.S. Army Test and Evaluation Command, or ATEC, is a direct reporting unit of the United States Army responsible for developmental testing, independent operational testing, independent evaluations, assessments, and experiments of Army equipment. [1] ATEC is located throughout the continental United States and Hawaii. Command headquarters is ...

The predecessor of modern electronic traction control systems can be found in high-torque, high-power rear-wheel-drive cars as a limited slip differential.A limited-slip differential is a purely mechanical system that transfers a relatively small amount of power to the non-slipping wheel, while still allowing some wheel spin to occur.
The Advanced Turbine Engine Company (ATEC) is an American aerospace joint venture created in 2006. A project of Honeywell International Inc. and Pratt & Whitney, ATEC was formed to compete for a government contract to create a 3,000 shaft horsepower engine to replace the existing 2,000 shaft horsepower T700 engine powering the U.S. Army's Sikorsky UH-60 Black Hawk and Boeing AH-64 Apache ...
Emergency Assist is a driver assistance system that monitors driver behavior by observing delays between the use of the accelerator and the brake; once a preset threshold of time has been exceeded the system will take control of the vehicle in order to bring it to a safe stop.
The versions are distinguished by the degree of rear steering and actuator for the rear steering rack, with the earliest version using a passive system to steer the rear wheels ("HICAS"), an intermediate version using a hydraulic actuator ("HICAS II"), and a later version using a hydraulic or electric actuator with additional programming ("Super HICAS").
The number of driving wheels on locomotives varied quite a bit. Some early locomotives had as few as two driving wheels (one axle). The largest number of total driving wheels was 24 (twelve axles) on the 2-8-8-8-2 and 2-8-8-8-4 locomotives. The largest number of coupled driving wheels was 14 (seven axles) on the ill-fated AA20 4-14-4 locomotive.
One edge of the wedge has a concave profile to contour to the wheel and increase the force necessary to overrun the chock. Most commonly, chocks are seen on aircraft and train cars. Automobiles usually have parking brakes on the rear wheels. If the rear axle is jacked off the ground with only the parking brake set, the vehicle may roll on the ...
