Rigid body, in physics, a simplification of the concept of an object to allow for modelling; Rigid transformation, in mathematics, a rigid transformation preserves distances between every pair of points; Rigidity (chemistry), the tendency of a substance to retain/maintain their shape when subjected to outside force
Rigidity is an ancient part of our human cognition. [4] Systematic research on rigidity can be found tracing back to Gestalt psychologists, going as far back as the late 19th to early 20th century with Max Wertheimer, Wolfgang Köhler, and Kurt Koffka in Germany.
In physics, a rigid body, also known as a rigid object, [2] is a solid body in which deformation is zero or negligible. The distance between any two given points on a rigid body remains constant in time regardless of external forces or moments exerted on it. A rigid body is usually considered as a continuous distribution of mass.
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.
In the physical science of dynamics, rigid-body dynamics studies the movement of systems of interconnected bodies under the action of external forces.The assumption that the bodies are rigid (i.e. they do not deform under the action of applied forces) simplifies analysis, by reducing the parameters that describe the configuration of the system to the translation and rotation of reference ...
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.
