How do you know if something is indeterminate or static determinate?
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.
How do you solve indeterminate structures?
The following methods are used to solve indeterminate structures:
- Flexibility method.
- Slope deflection method.
- Moment distribution method.
- Direct stiffness method.
- Relative Deformation co-efficient method.
Which is indeterminate structure?
Indeterminate structures are series of connected elements used in building members like beam, truss, and frames and will consist of additional elements not required for keeping the structure stable. Example of indeterminate structures is continuous beam, fixed beam, propped cantilever beams, etc.
What is an indeterminate problem?
(Math.) a problem which admits of an infinite number of solutions, or one in which there are fewer imposed conditions than there are unknown or required results.

What is the difference between determinate and indeterminate structure?
Determinate structures are analysed just by the use of basic equilibrium equations. By this analysis, the unknown reactions are found for the further determination of stresses. Redundant or indeterminate structures are not capable of being analysed by mere use of basic equilibrium equations.
Why are indeterminate structures used?
When we provide more support and/or member to structure than required for static stability, it makes structure indeterminate. By providing this excess member it ensures stability and also increase stiffness of the member or structure. Such as in case of truss we provide additional diagonal members to ensure stability.
What are the advantages of indeterminate structures?
Why are indeterminate structures used in engineering?
Indeterminate structures have more members and/or support reactions than required for static stability, so if a part (or member or support) of such a structure fails, the entire structure will not necessarily collapse, and the loads will be redistributed to the adjacent portions of the structure.

What is the force method for determinate structures?
Force Method for Analysis of Indeterminate Structures (Ref: Chapter 10)For determinate structures, the force method allows us to find internal forces (using equilibrium i.e. based on Statics) irrespective of the material information. Material (stress-strain) relationships are needed only to calculate deflections.
What is pseudo force?
What is Pseudo Force? A Pseudo force (also called a fictitious force, inertial force or d’Alembert force) is an apparent force that acts on all masses whose motion is described using a non-inertial frame of reference frame, such as rotating reference frame.
How to convert an indeterminate structure to a determinate one?
• Convert the indeterminate structure to a determinate one by removing some unknown forces / support reactions and replacing them with (assumed) known / unit forces. • Using superposition, calculate the force that would be required to achieve compatibility with the original structure.
What are the methods for analysis of indeterminate structures?
Force Method for Analysis of Indeterminate Structures Force Method for Analysis of Indeterminate Structures Number of unknown Reactions or Internal forces > Number of equilibrium equations Note: Most structures in the real world are statically indeterminate.
