Flexibility
Stiffness is the extent to which an object resists deformation in response to an applied force. The complementary concept is flexibility or pliability: the more flexible an object is, the less stiff it is. Calculations The stiffness, k, of a body is a measure of the resistance offered by an elastic body to deformation. For an elastic body with a single degree of freedom (DOF) (for example, stretching or compression of a rod), the stiffness is defined as k = \frac where, * F is the force on the body * \delta is the displacement produced by the force along the same degree of freedom (for instance, the change in length of a stretched spring) Stiffness is usually defined under quasi-static conditions, but sometimes under dynamic loading. In the International System of Units, stiffness is typically measured in newtons per meter (N/m). In Imperial units, stiffness is typically measured in pounds (lbs) per inch. Generally speaking, deflections (or motions) of an infinitesima ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Elasticity (physics)
In physics and materials science, elasticity is the ability of a body to resist a distorting influence and to return to its original size and shape when that influence or force is removed. Solid objects will deform when adequate loads are applied to them; if the material is elastic, the object will return to its initial shape and size after removal. This is in contrast to ''plasticity'', in which the object fails to do so and instead remains in its deformed state. The physical reasons for elastic behavior can be quite different for different materials. In metals, the atomic lattice changes size and shape when forces are applied (energy is added to the system). When forces are removed, the lattice goes back to the original lower energy state. For rubbers and other polymers, elasticity is caused by the stretching of polymer chains when forces are applied. Hooke's law states that the force required to deform elastic objects should be directly proportional to the distance of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stress (mechanics)
In continuum mechanics, stress is a physical quantity that describes forces present during deformation. For example, an object being pulled apart, such as a stretched elastic band, is subject to ''tensile'' stress and may undergo elongation. An object being pushed together, such as a crumpled sponge, is subject to ''compressive'' stress and may undergo shortening. The greater the force and the smaller the cross-sectional area of the body on which it acts, the greater the stress. Stress has dimension of force per area, with SI units of newtons per square meter (N/m2) or pascal (Pa). Stress expresses the internal forces that neighbouring particles of a continuous material exert on each other, while ''strain'' is the measure of the relative deformation of the material. For example, when a solid vertical bar is supporting an overhead weight, each particle in the bar pushes on the particles immediately below it. When a liquid is in a closed container under pressure, each par ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flexibility (anatomy)
Flexibility is the anatomy, anatomical range of motion, range of movement in a joint or series of joints, and length in muscles that cross the joints to induce a bending movement or motion. Flexibility varies between individuals, particularly in terms of differences in muscle length of multi-joint muscles. Flexibility in some joints can be increased to a certain degree by exercising, with stretching being a common exercise component to maintain or improve flexibility. Limberness is the condition of having flexibility to a positive or superior degree, which is also spoken of as a person ''having flexibility'' or ''being flexible''. Anatomical elements Joints The joints in a human body are surrounded by synovial membranes and articular cartilage which cover, cushion and nourish the joint and surfaces of each. Increasing muscular elasticity of the joint's range of mobility increases flexibility. Ligaments Ligaments are composed of two different tissues: white and yellow. The ...

Flexibility (engineering)
Flexibility is used as an attribute of various types of systems. In the field of engineering systems design, it refers to designs that can adapt when external changes occur. Flexibility has been defined differently in many fields of engineering, architecture, biology, economics, etc. In the context of engineering design one can define flexibility as the ability of a system to respond to potential internal or external changes affecting its value delivery, in a timely and cost-effective manner. Thus, flexibility for an engineering system is the ease with which the system can respond to uncertainty in a manner to sustain or increase its value delivery. Uncertainty is a key element in the definition of flexibility. Uncertainty can create both risks and opportunities in a system, and it is with the existence of uncertainty that flexibility becomes valuable. Flexible Manufacturing System Flexibility has been especially thoroughly studied for manufacturing Manufacturing is the cr ...

Flexibility (personality)
Flexibility is a personality trait that describes the extent to which a person can cope with changes in circumstances and think about problems and tasks in novel, creative ways. This trait comes into play when stressors or unexpected events occur, requiring that a person change their stance, outlook, or commitment. Flexibility, or psychological flexibility, as it is sometimes called, is the ability to adapt to situational demands, balance life demands, and commit to behaviors. Flexible personality should not be confused with cognitive flexibility, which is the ability to switch between two concepts, and to simultaneously think about multiple concepts. Researchers of cognitive flexibility describe it as the ability to switch one's thinking and attention between tasks. Measures/assessments Due to the different facets of the definition of psychological flexibility, it is difficult to measure. There are multiple questionnaires that attempt to do so. Acceptance and Action Questionnai ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cognitive Flexibility
Cognitive flexibility is an intrinsic property of a cognitive system often associated with the mental ability to adjust its activity and content, switch between different task rules and corresponding behavioral responses, maintain multiple concepts simultaneously and shift internal attention between them. The term ''cognitive flexibility'' is traditionally used to refer to one of the executive functions. In this sense, it can be seen as neural underpinnings of adaptive and flexible behavior. Most flexibility tests were developed under this assumption several decades ago. Nowadays, cognitive flexibility can also be referred to as a set of properties of the brain that facilitate flexible yet relevant switching between functional brain states. Cognitive flexibility varies during the lifespan of an individual. In addition, certain conditions such as obsessive–compulsive disorder are associated with reduced cognitive flexibility. Since cognitive flexibility is a vital component o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Labour Market Flexibility
The degree of labour market flexibility is the speed with which labour markets adapt to fluctuations and changes in society, the economy or production. This entails enabling labour markets to reach a continuous equilibrium determined by the intersection of the demand and supply curves. Labour unions can limit labor market flexibility by negotiating higher wages, benefits, and better working conditions with employers. In the words of Siebert, labour unions were seen to inhibit "the clearing functions of the market by weakening the demand for labor, making it less attractive to hire a worker by explicitly pushing up the wage costs or by introducing a negative shadow price for labor; by distorting the labor supply; and by impairing the equilibrating function of the market mechanism (for instance, by influencing bargaining behavior)." Theory The most well-known concept of labour market flexibility is given by Atkinson. Based on the strategies companies use, he notes that there can ...

First Album (Miss Kittin & The Hacker Album)
''First Album'' is the debut studio album by French electronic music duo Miss Kittin & The Hacker, released in 2001. It includes the tracks "1982" and "Frank Sinatra", two anthems of the late-1990s electroclash scene that had been first released on the EP ''Champagne'' (1998). Critical reception The album received generally favorable reviews. It earned a collective score of 68 out of 100 from Metacritic. Adam Bregman from Allmusic commented, "This French-Swiss duo pumps out retro-'80s-style disco beats and silly lyrics, creating a fun, goofy, ironic vibe ..They seem to be trying to reach over and above that generally stale genre, and they mostly succeed." ''Fact'' placed ''First Album'' at number 92 on its "100 best: Albums of the Decade" list. ''Mixer'' placed ''First Album'' at number five on its "Best Albums of 2002" list. ''Muzik'' placed it at number 15 on its list of the "Top 30 Albums of 2001". ''Resident Advisor'' ranked the album number 94 on its list of the "Top 1 ...

Flexibility (abstract Algebra)
In mathematics, particularly abstract algebra, a binary operation • on a set is flexible if it satisfies the flexible identity: : a \bullet \left(b \bullet a\right) = \left(a \bullet b\right) \bullet a for any two elements ''a'' and ''b'' of the set. A magma (that is, a set equipped with a binary operation) is flexible if the binary operation with which it is equipped is flexible. Similarly, a nonassociative algebra is flexible if its multiplication operator is flexible. Every commutative or associative operation is flexible, so flexibility becomes important for binary operations that are neither commutative nor associative, e.g. for the multiplication of sedenions, which are not even alternative. In 1954, Richard D. Schafer examined the algebras generated by the Cayley–Dickson process over a field and showed that they satisfy the flexible identity.Richard D. Schafer (1954) “On the algebras formed by the Cayley-Dickson process”, American Journal of Mathematics 76: 435� ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flexural Rigidity
Flexural rigidity is defined as the force couple required to bend a fixed non- rigid structure by one unit of curvature, or as the resistance offered by a structure while undergoing bending. Flexural rigidity of a beam Although the moment M(x) and displacement y generally result from external loads and may vary along the length of the beam or rod, the flexural rigidity (defined as EI) is a property of the beam itself and is generally constant for prismatic members. However, in cases of non-prismatic members, such as the case of the tapered beams or columns or notched stair stringers, the flexural rigidity will vary along the length of the beam as well. The flexural rigidity, moment, and transverse displacement are related by the following equation along the length of the rod, x: :\ EI \ = \int_^ M(x) dx + C_1 where E is the flexural modulus (in Pa), I is the second moment of area (in m4), y is the transverse displacement of the beam at x, and M(x) is the bending moment at ''x' ...
