Geometrical frustration is a phenomenon in condensed matter physics in which the geometrical properties of the crystal lattice or the presence of conflicting atomic forces forbid simultaneous minimization of the interaction energies acting at a given site. This may lead to highly degenerate energy level degenerate ground state s with a nonzero entropy at zero temperature. Or in simple terms, the substance can never be completely Freezing frozen , because the structure it forms does not have a single Ground state minimal energy state , so motion on a molecular scale continues even at absolute zero and even without input of energy . The term frustration , in the context of magnetism magnetic systems, is due to Gerard Toulouse 1977 . Frustrated magnetism magnetic systems have been studied for many years.

Summarize to Optics date June 2009 Geometrical optics , or ray optics , describes light Wave propagation propagation in terms of ray optics rays . The ray in geometric optics is an abstract object abstraction , or instrumentalism instrument , which can be used to approximately model how light will propagate. Light rays are defined to propagate in a rectilinear path as far as they travel in a homogeneous medium. Rays bend and may split in two at the wiktionary interface interface between two dissimilar optical medium media , may curve in a medium where the refractive index changes, and may be absorbed and reflected. Geometrical optics provides rules, which may depend on the color wavelength of the ray, for propagating these rays through an optical system. This is a significant simplification of optics that fails to account for optical effects such as diffraction and Interference wave propagation interference . It is an excellent approximation, however, when the wavelength is very small compared with the size of structures with which the light interacts. Geometric optics can be used to describe the geometrical aspects of Image imaging , including optical aberration s.

Image Bendradius.svg thumb 350px Bend radius Bend radius , which is measured to the inside curvature , is the minimum radius one can bend a pipe material pipe , tubing material tube , Sheet metal sheet , cable or hose tubing hose without kinking it, damaging it, or shortening its life. The smaller the bend radius, the greater is the material flexibility as the radius of curvature applications radius of curvature decreases , the curvature increases . The diagram below illustrates a cable with a seven centimeter bend radius. The minimum bend radius is the radius below which an object such as a cable should not be bent. Fiber optics The minimum bend radius is of particular importance in the handling of fiber optic cable s, which are often used in telecommunications . The minimum bending radius will vary with different cable designs. The manufacturer should specify the minimum radius to which the cable may safely be bent during installation, and for the long term. The former is somewhat shorter than the latter. The minimum bend radius is in general also a function of tensile stresses, e.g., during installation, while being bent around a sheave while the fiber or cable is under tension. If no minimum bend radius is specified, one is usually safe in assuming a minimum long term low stress radius not less than 15 times the cable diameter. Beside mechanical destruction, another reason why one should avoid excessive bending of fiber optic cables is to minimize microbending and macrobending losses. Microbending causes light attenuation induced by deformation of the fiber while macrobending causes the leakage of light through the fiber cladding and this is more likely to happen where the fiber is excessively bent. Microbending is explained better at photonics.com http www.photonics.com directory dictionary lookup.asp?url lookup&entrynum 3235&letter m Other applications Strain gauge s also have a minimum bending radius.

Unreferenced stub auto yes date December 2009 The Stokes radius , Stokes Einstein radius , or hydrodynamic radius R sub H sub , named after George Gabriel Stokes , is not the effective radius of a hydrated molecule in solution as often mentioned. Rather it is the radius of a hard sphere that diffuses at the same rate as the molecule. The behavior of this sphere includes hydration and shape effects. Since most molecules are not perfectly spherical, the Stokes radius is smaller than the effective radius or the rotational radius . A more extended molecule will have a larger Stokes radius compared to a more compact molecule of the same molecular weight. In liquids where there are considerable interactions between solute and solvent molecule, the Stokes radius of a perfect sphere is proportional to frictional coefficient f and inverse proportional to viscosity as follows math R H frac k BT 6 pi eta D . math where, math k B math is the Boltzmann constant in J K sup 1 sup , math D math is the diffusion coefficient in m sup 2 sup s sup 1 sup and math T math is the temperature in kelvin s. The frictional coefficient is determined by the size and shape of the molecule under consideration.

Image semicircle.svg frame A turn with the turning radius being r . The turning radius or turning circle of a vehicle is the size of the smallest circle circular turn i.e. U turn maneuver U turn that the vehicle is capable of making. The term turning radius is actually a misnomer, since the size of a circle is actually its diameter , not its radius . The less ambiguous term turning circle is preferred. As an example, Motor Trend refers to a curb to curb turning circle of a 2008 Cadillac CTS as 35.5 feet. By contrast, theAutoChannel.com refers to turning radius of the same car as 35.5 feet. It is often used as a generalization generalized term rather than a number numerical figure . For example, a vehicle with a very small turning radius may be described as having a tight turning radius . Two different measurements can be quoted for a vehicle. A curb or curb to curb turning circle will show the distance traveled by the wheels. The wall or wall to wall turning circle will include an allowance for the width of the whole car, including the overhang of the bodywork. For example, a van may have been quoted as having a turning circle in meters of 12.1 C 12.4 W . It may be easier to imagine that on a road with low curb s, you don t need to consider anything other than the tire s 12.1 meters , that is the curb turning radius, but if you were moving the vehicle inside a building, the corners of the vehicle might hit the walls so you need to consider the wall to wall turning radius 12.4 ... turning radius vehicle, although whether or not the turning radius is actually nonexistent is unclear ... rotation of their front and rear wheel sets, effectively giving them zero turning radius.

Combat radius refers to the distance from an airbase that a warplane can reach, patrol there for a set amount of time and return to base with minimal fuel left, thus completing a combat mission. For a given aircraft, its combat radius varies according to whether or not it carries external drop tanks , the level altitude of the combat mission, and the amount and weight of Ammunition Ordnance ammunition ordnance it is carrying An aircraft with drop tanks will have a greater combat radius than the same one without, due to the extra amount of fuel carried. An aircraft engaged in a low level lo combat mission will have a smaller combat radius than the same one engaged in a high level hi mission, due to higher fuel consumption at lower altitudes higher atmospheric pressure density of air air density . An aircraft with more and heavier ordnance will have a smaller combat radius than the same one with less and lighter ordnance, due to higher fuel consumption at heavier weights. The combat radius of an aircraft is often given with its mission profile without aerial refueling in air refueling . For example The F 16 Fighting Falcon s combat radius is 550 km 340 mi on a hi lo hi mission with six 450 kg 1,000 lb bombs. The F A 18 Hornet has a combat radius of 537 km 330 mi on a hi lo lo hi mission. The Su 27 Flanker s Range aircraft Range is 1,340 km 800 mi at sea level and 3,530 km 2,070 mi at high altitude. Combat radius is always smaller than maximum range , the distance which the aircraft can fly the farthest with maximum payload and without refueling, or ferry range , the distance the aircraft can fly the farthest with drop tanks, no ordnance and without refueling.
