Rigid spine syndrome, also known as congenital muscular dystrophy with rigidity of the spine (CMARS), is a rare and often debilitating neuromuscular disorder. It is characterized by progressive muscle stiffness and rigidity, particularly in the spine, which can severely limit mobility and impact quality of life. This condition is typically ...
Structural rigidity, a mathematical theory of the stiffness of ensembles of rigid objects connected by hinges; Rigidity (electromagnetism), the resistance of a charged particle to deflection by a magnetic field; Rigidity (mathematics), a property of a collection of mathematical objects (for instance sets or functions)
Rigidity can be a learned behavioral trait; for example, if the subject has a parent, boss, or teacher who demonstrated the same form of behavior towards them. [citation needed] Rigidity also has a genetic component and is commonly associated with autism. [16]
Rigidity is the property of a structure that it does not bend or flex under an applied force. The opposite of rigidity is flexibility.In structural rigidity theory, structures are formed by collections of objects that are themselves rigid bodies, often assumed to take simple geometric forms such as straight rods (line segments), with pairs of objects connected by flexible hinges.
The first result demonstrates when rigidity and infinitesimal rigidity of tensegrities are equivalent. Theorem. [ 20 ] Let ( G , p ) {\displaystyle (G,p)} be a d {\displaystyle d} -dimensional tensegrity framework where: the vertices of G {\displaystyle G} are realized as a strictly convex polygon; the bars form a Hamilton cycle on the boundary ...
In particle physics, rigidity is a measure of the resistance of a particle to deflection by magnetic fields, defined as the particle's momentum divided by its charge. For a fully ionised nucleus moving at relativistic speed , this is equivalent to the energy per atomic number.
So, if this is the sort of distinction you care about, we’ve got some more brain food for you: With 645 meanings, the most complicated word in English is only three letters long. Sources:
is the rigidity modulus of the material, J {\displaystyle J} is the torsion constant for the section. Note that the torsional stiffness has dimensions [force] * [length] / [angle], so that its SI units are N*m/rad.
