The number of independent equations to be satisfied for static equilibrium in a space structure is. Kinematic determinacy can be loosely used to classify an arrangement of structural members as a structure stable instead of a mechanism unstable.
Mathematically, the mass matrix of the structure must have full rank. This technology-related article is a stub. This article does not cite any sources. The structure has no possible mechanisms, i.
Kinematic determinacy is a term used in structural mechanics to describe a structure where material compatibility conditions alone can be used to calculate deflections. Degree of kinematic indeterminacy of a pin-jointed plane frame is given by Author: Number of unknown internal forces in each member of a rigid jointed plane frame is.
A pin-jointed plane frame is unstable ifwhere m is number of members, r is reaction components and j is number of joints. The principles of kinematic determinacy are used to design precision devices such as mirror mounts for optics, and precision linear motion bearings. Please help improve this article by adding citations to reliable sources. The number of independent displacement components at each joint of a rigid-jointed space frame is.
