Difference between static and kinematic indeterminate structure
Answers
In statics, a structure is statically indeterminate (or hyperstatic) when the static equilibrium equations are insufficient for determining the internal forces and reactions on that structure. When the number of unknown forces is more than the number of equilibrium equations required to find the forces, then the system is said to be statically indeterminate.
The indeterminacy of a structure that is expressed in terms of its degrees of freedom is known as the kinematic indeterminacy. Kinematic determinacy is used in structural mechanics to describe a structure where material compatibility conditions alone can be used to calculate deflections. It is used specifically in the stiffness method of analysis where the unknowns are the displacements
