Since the centrifugal force of the parts of the earth, arising from the earth's diurnal motion, which is to the force of gravity as 1 to 289, raises the waters under the equator to a height exceeding that under the poles by 85472 Paris feet, as above, in Prop. XIX., the force of the sun, which we have now shewed to be to the force of gravity as ...
Franks had noted that his test tubes often broke when subjected to severe centrifugal force. He had solved the problem by first inserting them into larger and stronger liquid-filled bottles. In 1940, the anti gravity suit was developed under the name Franks Flying Suit by Wilbur R. Franks and his colleagues at the Banting and Best Medical ...
Centrifugal force is a fictitious force in Newtonian mechanics (also called an "inertial" or "pseudo" force) that appears to act on all objects when viewed in a rotating frame of reference. It appears to be directed radially away from the axis of rotation of the frame.
In 1865, he invented a simple machine for extracting honey from the comb by means of centrifugal force. [4] [5] The announcement was made at the 14th German and Austrian Beekeepers Conference in Brno (now in the Czech Republic) held from September 12 to September 14, 1865. While he shared the basic idea only with a few beekeepers the first day ...
By 1912, Einstein had become convinced of a close relationship between gravitation and pseudo-forces such as centrifugal force: Such a system K , according to the equivalence principle, is strictly equivalent to a system at rest in which a matter-free static gravitational field of a certain kind exists.
The Winans Steam Gun of 1858–1861 was a steam-powered centrifugal gun used during the American Civil War by the Confederates. It used steam power and centrifugal forces to propel projectiles. It was not used successfully in battle. Prototype Holman Projector, an anti-aircraft grenade projector, in action in 1940
Artificial gravity, or rotational gravity, is thus the appearance of a centrifugal force in a rotating frame of reference (the transmission of centripetal acceleration via normal force in the non-rotating frame of reference), as opposed to the force experienced in linear acceleration, which by the equivalence principle is indistinguishable from ...
Samuel Cleland Davidson with a huge centrifugal fan he designed and manufactured, probably for ventillating a mine shaft. The Sirocco Works on the River Lagan, Belfast, during demolition in 2009 In 1864 Davidson left his job to work for his father, James Davidson who owned a flour mill close to the site of the later Sirocco works.
