Example: Juan de Fuca oceanic plate colliding with the North American Plate created the Cascade Mountain Range in the western U.S. The Andes Mountains are another example. Continental vs. Continental Convergent Boundaries What happens: Two thick continental plates collide. The plates do not subduct. They crumple, fold, fault, and create
Rack and Pinion Gears Information. Rack and pinion gears are used to convert rotation into linear motion. The flat, toothed part is the rack and the gear is the pinion. A piston coaxial to the rack provides hydraulic assistance force, and an open centered rotary valve controls the assist level. A rack and pinion gears system is composed of two gears.
A good example of a rack and pinion gear system can be seen on trains that are designed to travel up steep inclines. The wheels on a train are steel and they have no way of griping the steel track. Usually the weight of the train is enough to allow the train to travel safely and at speed along the track.
