The heat eventually turns the wood at the point of contact into charcoal, which is ground to a powder by the friction, that collects into the "V" notch. Continuing operation eventually ignites the charcoal dust producing a tiny ember, which can be used to start a fire in a "tinder bundle" (a nest of stringy, fluffy, and combustible material). [4]
A manual transmission (MT), also known as manual gearbox, standard transmission (in Canada, the United Kingdom and the United States), or stick shift (in the United States), is a multi-speed motor vehicle transmission system where gear changes require the driver to manually select the gears by operating a gear stick and clutch (which is usually ...
Ixion engine on a Komet motorised bicycle, ca. 1902. This system is used, for example, to drive the spools in some tape recorders.In a typical configuration, one of the cylinders is the axle of an electric motor, say 1 mm in diameter, while the other is a disk with a hard rubber rim, say 50 mm in diameter, yielding a 1:50 mechanical advantage.
Design for manufacturability – (also sometimes known as design for manufacturing or DFM), is the general engineering practice of designing products in such a way that they are easy to manufacture. The concept exists in almost all engineering disciplines, but the implementation differs widely depending on the manufacturing technology.
An automated manual transmission (AMT) is essentially a conventional manual transmission that uses automatic actuation to operate the clutch and/or shift between gears. Many early versions of these transmissions were semi-automatic in operation, such as Autostick , which automatically control only the clutch , but still require the driver's ...
A short piece of fire hose, usually 10 to 20 feet (6.1 m) long, of large diameter, greater than 2.5 inches (64 mm) and as large as 6 inches (150 mm), used to move water from a fire hydrant to the fire engine, when the fire apparatus is parked close to the hydrant. Solid stream A fire-fighting water stream emitted from a smooth-bore nozzle.
The factory floor of Globe Manufacturing may seem like your average textile manufacturing space -- from its daylight yellow walls, to the Technicolor knickknacks dotting individual workstations.
Friction disk for a dry clutch. A clutch is a mechanical device that allows an output shaft to be disconnected from a rotating input shaft. [1] The clutch's input shaft is typically attached to a motor, while the clutch's output shaft is connected to the mechanism that does the work.
