compliant mechanisms are usually designed using two techniques, the first being a pseudo-rigid-body model and the second, the topology optimization. other techniques are being conceived to design these mechanisms. compliant mechanisms manufactured in a plane that have motion emerging from said plane are known as lamina emergent mechanisms lems .
a chairlift consists of numerous components to provide safe efficient transport. terminology. especially at american ski areas, chairlifts are referred to with a ski industry vernacular.a one-person lift is a 'single', a two-person lift is a 'double', a three-person lift a “triple”, four-person lifts are “quads”, and a six-person lift is a 'six pack'.
a portable emissions measurement system pems is a vehicle emissions testing device that is small and light enough to be carried inside or moved with a motor vehicle that is being driven during testing, rather than on the stationary rollers of a dynamometer that only simulates real-world driving.
the boomsar is a mobile ultra-wideband synthetic aperture radar uwb sar system designed by the u.s. army research laboratory arl in the mid-1990s to detect buried landmines and ieds.mounted atop a 45-meter telescoping boom on a stable moving vehicle, the boomsar transmits low frequency 50 to 1100 mhz short-pulse uwb signals over the side of the vehicle to scope out a 300-meter range area .
this is the comparison of orbital launch systems page. it contains two lists of conventional orbital launch systems individual rocket configurations , separated by operational status. for the simple list of all conventional launcher families, see: comparison of orbital launchers families.for the list of predominantly solid-fueled orbital launch systems, see: comparison of solid-fueled orbital .
saconney’s man lifting system contained a motorcar, trailer, and a winch that was driven by the car's engine. the system was also installed aboard the ship the edgar quinet in 1911. in november 1912, saconney became head of the laboratory of meteorology and aerial photography of chalais-meudon.
in aircraft design and aerospace engineering, a high-lift device is a component or mechanism on an aircraft's wing that increases the amount of lift produced by the wing. the device may be a fixed component, or a movable mechanism which is deployed when required. common movable high-lift devices include wing flaps and slats. fixed devices include leading-edge slots, leading edge root extensions, and boundary layer control systems.
electrodynamic suspension eds is a form of magnetic levitation in which there are conductors which are exposed to time-varying magnetic fields. this induces eddy currents in the conductors that creates a repulsive magnetic field which holds the two objects apart.. these time varying magnetic fields can be caused by relative motion between two objects. in many cases, one magnetic field is a .
the mineral dolomite crystallizes in the trigonal-rhombohedral system. it forms white, tan, gray, or pink crystals. dolomite is a double carbonate, having an alternating structural arrangement of calcium and magnesium ions. unless it is in fine powder form, it does not rapidly dissolve or effervesce fizz in cold dilute hydrochloric acid as .
paul bevilaqua is an aeronautics engineer at lockheed martin in california. in 1990, he invented the lift fan for the joint strike fighter f-35b along with fellow skunk works engineer paul shumpert.
developed by the laboratory hydraulic human power extender is a tool with a carrying capacity of 500 pounds, intended to help loading and unloading aircraft. two sets of piezoelectric force sensors measure forces for arbitrary force augmentation and force reflection in the machine while the six axes.
a hovertrain is a type of high-speed train that replaces conventional steel wheels with hovercraft lift pads, and the conventional railway bed with a paved road-like surface, known as the track or guideway.the concept aims to eliminate rolling resistance and allow very high performance, while also simplifying the infrastructure needed to lay new lines. .
a simple rotary evaporator system was invented by lyman c. cr. it was first commercialized by the swiss company büchi in 1957. in research the most common form is the 1l bench-top unit, whereas large scale e.g., 20l-50l versions are used in pilot plants in commercial chemical operations.
the ames research center arc , also known as nasa ames, is a major nasa research center at moffett federal airfield in california's silicon valley.it was founded in 1939 as the second national advisory committee for aeronautics naca laboratory. that agency was dissolved and its assets and personnel transferred to the newly created national aeronautics and space administration nasa on .
the basic concept is the same as the classic hovertrain, but replaces the active hovercraft system of pumps and lift pads with wings, using the efficient generation of lift from the wing-in-ground-effect.
dolomite /ˈdɒləmaɪt/ is an anhydrous carbonate mineral composed of calcium magnesium carbonate, ideally camg co3 2. the term is also used for a sedimentary carbonate rock composed mostly of the mineral dolomite. an alternative name sometimes used for the dolomitic rock type is dolostone .
in robot combat, a self-righting mechanism or srimech sometimes spelled as srimec or shrimech is a device used to re-right a robot should it get flipped. biohazard of battlebots was the first robot to self-right.
berkeley robotics and human engineering laboratory is managed and operated by university of california, berkeley.the lab conducts scientific research on the design and control of a class of robotic systems worn or operated by humans to increase human mechanical strength.
the timeline of earth science satellites shows, in chronological order, those successful satellites with a program of earth science. sputnik 1, while the first satellite ever launched, did not conduct earth science. explorer 1 was the first satellite to make an earth science discovery when it found the van allen belts
