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 ...
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.
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 first PhD in engineering (technically, applied science and engineering) awarded in the United States went to Willard Gibbs at Yale University in 1863; it was also the second PhD awarded in science in the U.S. [46] In 1990, with the rise of computer technology, the first search engine was built by computer engineer Alan Emtage.
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]
Various machine components used in mechanical engineering. Mechanical engineering is the study of physical machines that may involve force and movement. It is an engineering branch that combines engineering physics and mathematics principles with materials science, to design, analyze, manufacture, and maintain mechanical systems. [1]
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 ]
Education in mechanical engineering has historically been based on a strong foundation in mathematics and science. [ 44 ] In the 20th century, many governments began regulating both the title of engineer and the practice of engineering , requiring a degree from an accredited university and to past a qualifying test.
