Such an instrument is expected to be especially useful if it could be used to measure the elasticity of heavy pastes such as printing inks, paints, adhesives, molten plastics, and bread dough, for the elasticity is related to those various properties termed `` length '', `` shortness '', `` spinnability '', etc., which are usually judged by subjective methods at present.

Depending on the elasticity of the arrow, some of the energy is also absorbed by compressing the arrow, primarily because the release of the bowstring is rarely in line with the arrow shaft, causing it to flex out to one side.

Exterior " latex " house paints may also be a " co-polymer " blend, but the very best exterior water-based paints are 100 % acrylic, due to elasticity and others, but 100 percent acrylic resins cost double as much as vinyl and PVA ( polyvinyl acetate ) is even cheaper, so paint companies make many combinations of them to match the market.

The modulus of elasticity of beryllium is approximately 50 % greater than that of steel.

While bone is essentially brittle, it does have a significant degree of elasticity, contributed chiefly by collagen.

A yarn's usefulness is judged by several factors, such as its loft ( its ability to trap air ), its resilience ( elasticity under tension ), its washability and colorfastness, its hand ( its feel, particularly softness vs. scratchiness ), its durability against abrasion, its resistance to pilling, its hairiness ( fuzziness ), its tendency to twist or untwist, its overall weight and drape, its blocking and felting qualities, its comfort ( breathability, moisture absorption, wicking properties ) and its appearance, which includes its color, sheen, smoothness and ornamental features.

Of these types, wool is generally favored for crochet, chiefly owing to its superior elasticity, warmth and ( sometimes ) felting ; however, wool is generally less convenient to clean and some people are allergic to it.

* Economics, η is the elasticity.

Gluten's attainable elasticity is proportional to its content of glutenins with low molecular weights as this portion contains the preponderance of the sulfur atoms responsible for the cross-linking in the network.

The strength and elasticity of gluten in flour is measured in the baking industry using a farinograph.

Knitted garments are often more form-fitting than woven garments, since their elasticity allows them to follow the body's curvature closely ; by contrast, curvature is introduced into most woven garments only with sewn darts, flares, gussets and gores, the seams of which lower the elasticity of the woven fabric still further.

This elasticity is unavailable from woven fabrics, which only stretch along the bias.

A yarn's usefulness for a knitting project is judged by several factors, such as its loft ( its ability to trap air ), its resilience ( elasticity under tension ), its washability and colorfastness, its hand ( its feel, particularly softness vs. scratchiness ), its durability against abrasion, its resistance to pilling, its hairiness ( fuzziness ), its tendency to twist or untwist, its overall weight and drape, its blocking and felting qualities, its comfort ( breathability, moisture absorption, wicking properties ) and of course its look, which includes its color, sheen, smoothness and ornamental features.

Of these types, wool is generally favored for knitting, chiefly owing to its superior elasticity, warmth and ( sometimes ) felting ; however, wool is generally less convenient to clean and some people are allergic to it.

The development of the ultrasonic transducer allowed for easy measurement of viscosity and elasticity in fluids and solids, resulting in huge advances in materials research.

Dulong also worked on the elasticity of steam, on the measurement of temperatures, and on the behavior of elastic fluids.

Some non-Newtonian fluids, such as viscoelastic fluids, will also exhibit elasticity in certain conditions.

The realization that soft matter contains innumerable examples of symmetry breaking, generalized elasticity, and many fluctuating degrees of freedom has re-invigorated classical fields of physics such as fluids ( now generalized to non-Newtonian and structured media ) and elasticity ( membranes, filaments, and anisotropic networks are all important and have common aspects ).

These meandering loops can be stretched easily in different directions, which gives knitting much more elasticity than woven fabrics ; depending on the yarn and knitting pattern, knitted garments can stretch as much as 500 %.

The diameter affects the size of stitches, which affects the gauge of the knitting and the elasticity of the fabric.

The classical theory of elasticity deals with the behaviour of elastic solids under small deformations, for which ,( 1 ) according to Hooke's Law, stress is directly proportional to the strain — but independent of the rate of strain, or how fast the deformation was applied, and ( 2 ) the strains are completely recoverable once the stress is removed.

The difference in material behaviour is characterized by the level and nature of elasticity present in the material when it deforms, which takes the material behaviour to the non-Newtonian regime.

Because deadweight costs are related to the elasticity of supply and demand for a good, it follows that putting the highest tax rates on the goods for which there is most inelastic supply and demand will result in the least overall deadweight costs.

The movement of the slowly oscillating tissue is used to determine the elasticity of the material, which can then be used to distinguish healthy tissue from the unhealthy tissue.

While collagen ( mostly type I ) provides strength and structural support to the tissue, which are useful to withstanding stress and resisting deformation when subjected to a force, elastin fibers bring elasticity to the tissue, allowing it to return to its original shape after deformation.

Owing to its high levels of gluten ( which give the dough sponginess and elasticity ), common wheat ( also known as bread wheat ) is the most common grain used for the preparation of bread.

Natural rubber is often vulcanized, a process by which the rubber is heated and sulfur, peroxide or bisphenol are added to improve resistance and elasticity, and to prevent it from perishing.

Tips were generally made from bamboo for its elasticity which could throw the bait further and more accurately.

In 1660, Hooke discovered the law of elasticity which bears his name and which describes the linear variation of tension with extension in an elastic spring.

" Hooke's work on elasticity culminated, for practical purposes, in his development of the balance spring or hairspring, which for the first time enabled a portable timepiece – a watch – to keep time with reasonable accuracy.

Another common condition in older patients is presbyopia, which is caused by the eye's crystalline lens losing elasticity, progressively reducing the ability of the lens to accommodate ( i. e. to focus on objects close to the eye ).

Cork is composed of suberin, a hydrophobic substance, and because of its impermeability, buoyancy, elasticity, and fire resistance, it is used in a variety of products, the most common of which is for wine stoppers.

Short compression struts mean long tension lines which mean extreme elasticity.

One of the pioneers of elasticity theory, she won the grand prize from the Paris Academy of Sciences for her essay on the subject.

In 1814 he published his own work on elasticity, and did not acknowledge Germain's help ( although he had worked with her on the subject and, as a judge on the Academy commission, had had access to her work ).

The equations are then discretized onto a grid using the finite difference method and solved subject to the constraints of Gauss's law and Linear elasticity.

To establish the element's stiffness or flexibility relation, we can use the mechanics of materials approach for simple one-dimensional bar elements, and the elasticity approach for more complex two-and three-dimensional elements.

From this they created a differential equation for the shape of the bundle relating the elasticity, gravity, and orientational disorder and extracted a simple equation of state to relate the swelling pressure to the measured random curvatures of individual hairs.

It seems that most indicators of environmental degradation are monotonically rising in income though the ' income elasticity ' is less than one and is not a simple function of income alone.

Moreover, as, elasticity of rods can be given a simple variational form.

In economics, elasticity is the measurement of how changing one economic variable affects others.

Cross price elasticity is a measurement of how far, and in which direction, the curve shifts horizontally along the x-axis.

Pulse contour analysis is a non-invasive method that allows easy measurement of arterial elasticity to identify patients at risk for cardiovascular events.

The midpoint arc elasticity formula was advocated by R. G. D. Allen due to the following properties: ( 1 ) it is symmetric with respect to the two prices and two quantities, ( 2 ) it is independent of the units of measurement, and ( 3 ) it yields a value of unity if the total revenues at two points are equal.

Thus, if the elasticity is inferred from the measurements of the scattering intensity, and the viscosity is determined independently ( via mechanical methods such as ultrasonic attenuation ) measurement of the relaxation rate yields information on the pore size distribution contained within the polymer network, e. g large fluctuations in polymer density near the critical point yield large density differentials with a corresponding bimodal distribution of porosity.
