Ecological engineering utilizes systems ecology with engineering design to obtain a holistic view of the interactions within and between society and nature. Ecosystem simulation with Energy Systems Language (also known as energy circuit language or energese) by Howard Odum is one illustration of this systems ecology approach. [ 16 ]
The Shakers were the pioneering inventors of the broom vise, which made today's flat broom possible. According to Lowder (2012) this was "the only major update to the broom since the introduction of the broom machine" and permitted flattening and sewing, instead of mere lashing to a round handle. This design innovation is evidenced in modern ...
Visualization of how a push broom scanner captures imagery. The dark purple squares represent the subset of the area seen by the scanner at any given time and the lighter purple squares show previously scanned areas. A push broom scanner, also known as an along-track scanner, is a device for obtaining images with spectroscopic sensors.
Wooden broom handles are commonly made from hardwood or fir. Commercial wood broom handles are painted or finished. [24] Lacquers can increase the lifespan of the broom's handle in addition to serving an aesthetic purpose. [22] Wooden broom handles are often about 42 inches long and seven-eighths to one and one-eighth inches in diameter. [18]
A metal lathe is an example of a machine tool. A machine tool is a machine for handling or machining metal or other rigid materials, usually by cutting, boring, grinding, shearing, or other forms of deformations. Machine tools employ some sort of tool that does the cutting or shaping.
Molecular motors are natural (biological) or artificial molecular machines that are the essential agents of movement in living organisms. In general terms, a motor is a device that consumes energy in one form and converts it into motion or mechanical work ; for example, many protein -based molecular motors harness the chemical free energy ...
A compound machine is a machine formed from a set of simple machines connected in series with the output force of one providing the input force to the next. For example, a bench vise consists of a lever (the vise's handle) in series with a screw, and a simple gear train consists of a number of gears (wheels and axles) connected in series.
The following outline is provided as an overview of and topical guide to machines: Machine – mechanical system that provides the useful application of power to achieve movement. A machine consists of a power source, or engine, and a mechanism or transmission for the controlled use of this power.
