Poisson's ratio of a material defines the ratio of transverse strain (x direction) to the axial strain (y direction)In materials science and solid mechanics, Poisson's ratio (symbol: ν ()) is a measure of the Poisson effect, the deformation (expansion or contraction) of a material in directions perpendicular to the specific direction of loading.
LEXAN is the flagship product of SABIC Innovative Plastics (formerly GE Plastics) and is used in everything from CDs and DVDs to car bumpers. Though Dr. Fox is often credited with the invention of LEXAN resin, the patent and agreement to share the plastic between Bayer and General Electric is much more complicated than the simplistic "Father of ...
(OC 6 H 4) 2 C(CH 3) 2 CO) n + O 2, R* → (OC 6 H 4) 2 C(CH 3 CH 2)CO) n. This product can be further oxidized to form smaller unsaturated compounds. This can proceed via two different pathways, the products formed depends on which mechanism takes place. [38] Pathway A (OC 6 H 4) 2 C(CH 3 CH 2)CO + O 2, H* HO(OC 6 H 4)OCO + CH 3 COCH 2 (OC 6 H ...
The use of larger gauge stranded aluminum wire (larger than #8 AWG) is fairly common in much of North America for modern residential construction. Aluminum wire is used in residential applications for lower voltage service feeders from the utility to the building. This is installed with materials and methods as specified by the local electrical ...
Common fill power values range from about 300 cubic inches per ounce (170 cm 3 /g) for feathers to around 900 in 3 /oz (520 cm 3 /g) for the highest quality goose down. The rare and relatively expensive down of certain wild waterfowl species such as the Muscovy duck or Common eider can have higher fill powers than goose down. Higher fill powers ...
Fill factor may refer to: Fill factor (solar cell), the ratio of maximum obtainable power to the product of the open-circuit voltage and short-circuit current; Fill factor (image sensor), the ratio of light-sensitive area of a pixel to total pixel area in an image sensor; In vision science, the ratio of view areas to the object visible areas.
[1] [2] Highest density is known only for 1, 2, 3, 8, and 24 dimensions. [3] Many crystal structures are based on a close-packing of a single kind of atom, or a close-packing of large ions with smaller ions filling the spaces between them. The cubic and hexagonal arrangements are very close to one another in energy, and it may be difficult to ...
In most modern incandescent bulbs, part of the wire inside the bulb acts like a fuse: if a broken filament produces an electrical short inside the bulb, the fusible section of wire will melt and cut the current off to prevent damage to the supply lines. A hot glass bulb may fracture on contact with cold objects.
