How do you find the degree of indeterminacy?
For a given structure the degree of static indeterminacy is unique but different sets of static unknowns can be selected as redundant forces, as we will see later on in the document. To obtain the degree of static indeterminacy we compare the number of static unknowns with the number of equilibrium equations.
What is determinacy and indeterminacy?
A statically determinate structure is one that is stable and all unknown reactive forces can be determined from the equations of equilibrium alone. A statically indeterminate structure is one that is stable but contains more unknown forces than available equations of equilibrium.
What is degree of kinematic indeterminacy?
4.1 Definition The degree of kinematic indeterminacy (DKI) is the minimum number of movements (degrees of freedom, DOF) with which the kinematic configuration of the overall structure can be defined, that is, the number of unknown independent movements of the structure.
What is meant by indeterminacy?
Meaning of indeterminacy in English the state of not being measured, counted, or clearly known: A sort of moral indeterminacy has always been at the centre of his art.
What is indeterminacy structure?
If a structure cannot be analyzed for external and internal reactions using static equilibrium conditions alone then such a structure is called indeterminate structure.
What is degree of static and kinematic indeterminacy?
The degree of static indeterminacy or degree of redundancy shows the number of additional equations required to solve the system. External indeterminacy is related to the support system of the structure whereas internal indeterminacy is related to the internal stress in the members of the structure.
What is the zone of indeterminacy?
In ‘Zones of Indeterminacy: Art, Body and Politics in Daoist Thought’, Peng Yu foregrounds the concept of Xu from Zhuangzi’s philosophical writings, and relates this to questions about the political body. Xu refers to a Daoist notion of ambiguity, though it remains ambiguous as to how to fully define the term.
What is the difference between static and kinematic indeterminacy?
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.
What is the static and kinematic indeterminacy?
If it cannot be analyzed by the equation of static equilibrium alone, then it is called a statically indeterminate structure. Eg: Fixed beam. A structural system is said to be kinematically indeterminate if the displacement components of its joints cannot be determined by the compatibility equation alone.
What is the difference between static indeterminacy and kinematic indeterminacy?
Answer: Static indeterminacy- when internal forces and reactions are greater than static equilibrium equations. Kinematic indeterminacy- when the number of unknown displacement is greater than the number of compatibility equations.
