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.
When the rack-and-pinion is in a power-steering system, the rack has a slightly different design. Part of the rack contains a cylinder with a piston in the middle. The piston is connected to the rack. There are two fluid ports, one on either side of the piston.
