3. A machine for bending, flanging, folding, and forming sheet metal.
Device used to slow down or stop the movement of a moving body or vehicle. The mechanically applied caliper brake used on bicycles uses a scissor action to press hard rubber blocks against the wheel rim. The main braking system of an automobile works hydraulically: when the driver depresses the brake pedal, liquid pressure forces pistons to apply brakes on each wheel.
Two types of automobile brakes are used. Disc brakes are used on the front wheels of some automobiles and on all wheels of sports and performance automobiles, since they are the more efficient and less prone to fading (losing their braking power) when they get hot. Braking pressure forces brake pads against both sides of a steel disc that rotates with the wheel. Drum brakes are fitted on the rear wheels of some automobiles and on all wheels of some passenger automobiles. Braking pressure forces brake shoes to expand outward into contact with a drum rotating with the wheels. The brake pads and shoes have a tough friction lining that grips well and withstands wear.
Many trucks and trains have air brakes, which work by compressed air. On landing, jet planes reverse the thrust of their engines to reduce their speed quickly. Space vehicles use retrorockets for braking in space and use the air resistance, or drag of the atmosphere, to slow down when they return to Earth.

Handle bent at right angles and connected to the shaft of a machine; it is used to transmit motion or convert reciprocating (back-and-forward or up-and-down) movement into rotary movement, or vice versa.
Although similar devices may have been employed in antiquity and as early as the 1st century in China and the 8th century in Europe, the earliest recorded use of a crank in a water-raising machine is by Arab mathematician al-Jazari in the 12th century. Not until the 15th century, however, did the crank become fully assimilated into developing European technology.—
