2Bearing (mechanical) — A bearing is a device to allow constrained relative motion between two or more parts, typically rotation or linear movement. Bearings may be classified broadly according to the motions they allow and according to their principle of operation as… …
3Free radical reaction — A free radical reaction is any chemical reaction involving free radicals. This reaction type is abundant in organic reactions. Two pioneering studies into free radical reactions have been the discovery of the triphenylmethyl radical by Moses… …
4Free Lunch — A situation in which a good or service is received at no cost, with the true cost of the good or service ultimately borne by some party, which may even include the recipient. A free lunch was often offered during the 1800s to bar patrons who… …
5Fluid bearing — Fluid bearings are bearings which solely support the bearing s loads on a thin layer of liquid or gas.They can be broadly classified as fluid dynamic bearings, hydrostatic or gas bearings. They are frequently used in high load, high speed or high …
6Plain bearing — Crankshaft plain bearing shells A plain bearing, also known as a plane bearing[1] or a friction bearing[2] is the simplest type of bearing, comprising just a bearing surface and no rolling elem …
7Neuroscience of free will — refers to recent neuroscientific investigations shedding light on the question of free will, which is a philosophical and scientific question as to whether, and in what sense, rational agents exercise control over their actions or decisions. As… …
8Foil bearing — Foil bearings are a type of air bearing. A shaft is supported by a compliant, spring loaded foil journal lining. Once the shaft is spinning fast enough, the working fluid (usually air), pushes the foil away from the shaft so that there is then no …
9Rolling-element bearing — A rolling element bearing is a bearing which carries a load by placing round elements between the two pieces. The relative motion of the pieces causes the round elements to roll with very little rolling resistance and with little sliding.One of… …
10Magnetic bearing — A magnetic bearing A magnetic bearing is a bearing which supports a load using magnetic levitation. Magnetic bearings support moving machinery without physical contact, for example, they can levitate a rotating shaft and permit relative motion… …
