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.
The rack and pinion helm includes a pinion gear fitted directly on the steering shaft that engages a rack gear in a tubular housing. Rack steering is the most efficient mechanical system for moving the cable, but its drawback is its width.
