Rigidity
31rigidity of gyroscope — A property of a gyroscope by which its axis will remain in a fixed direction in space unless the rotor shaft is acted upon by an external torque …
32Mostow rigidity theorem — In mathematics, Mostow s rigidity theorem, or strong rigidity theorem, or Mostow–Prasad rigidity theorem, essentially states that the geometry of a finite volume hyperbolic manifold of dimension greater than two is determined by the fundamental… …
33Born rigidity — Born rigidity, proposed by and later named after Max Born, is a concept in special relativity. It is one answer to the question of what, in special relativity, corresponds to the rigid body of non relativistic classical mechanics. The defining… …
34Flexural rigidity — is defined as the force couple required to bend a rigid structure to a unit curvature.In a beam or rod, flexural rigidity varies along the length as a function of x shown in the following equation:: EI {dy over dx} = int {0}^{x} M(x) dx + C 1… …
35Ригидность (Rigidity) — (в неврологии) сопротивление выполнению пассивных движений конечностью. Чаще всего ригидность является одним из симптомов паркинсонизма. Сопротивление гладких мышц называется пластической ригидностью (plastic или lead pipe rigidity);… …
36decerebrate rigidity — an abnormal body posture produced by decerebration. In experimental animals it is marked by rigid extension of the lower limbs (hindlimbs in a quadruped). In humans it is manifested by the person lying in rigid extension with the upper limbs… …
37progressive encephalomyelitis with rigidity — a syndrome resembling the stiff person syndrome, characterized by brainstem dysfunction, rigidity, and spinal myoclonus …
38clasp-knife rigidity — an exaggerated stretch reflex of skeletal muscles seen in spasticity and decerebrate rigidity, resembling the opening of a penknife or clasp knife; there is increased resistance to the extensors (induced by passive flexion of a joint), which… …
39lead pipe rigidity — diffuse muscular rigidity resembling the resistance to bending of a thin walled metal pipe; seen in parkinsonism …
40modulus of rigidity — šlyties modulis statusas T sritis Standartizacija ir metrologija apibrėžtis Liestinio įtempio ir santykinės šlyjamosios deformacijos dalmuo, t. y. G = τ/γ ; čia τ – liestinis įtempis, γ – santykinė šlyjamoji deformacija. atitikmenys: angl.… …
