In aeronautics, air brakes, or speed brakes, are a type of flight control surface used on an aircraft to increase the drag on the aircraft. [1] When extended into the airstream, air brakes cause an increase in the drag on the aircraft. When not in use, they conform to the local streamlined profile of the aircraft in order to help minimize drag. [2]
A polytunnel (also known as a polyhouse, hoop greenhouse or hoophouse, grow tunnel or high tunnel) is a tunnel typically made from steel and covered in polyethylene, usually semi-circular, square or elongated in shape.
The type of brake system in use only affects trucks and large mass vehicles, which cannot supply enough force to match the static frictional force. [1] [Note 2] The braking distance is one of two principal components of the total stopping distance. The other component is the reaction distance, which is the product of the speed and the ...

With the clutch off, so the shaft does not spin, the idlers in the two differentials are fixed in place. This is just like the controlled differential with the brake on. When the steering clutch is engaged, the shaft spins one of the idler sets forward and the other backward, causing one track to speed up and the other to slow down. [2]
Once the debris was removed, Logano’s car was back at full speed and he worked his way back through the field. The race finished before 10 p.m. ET after a long rain delay shortly after the green ...
