Statically indeterminacy is the condition when less equations are available for equilibrium than the unknown loadings. This not only creates a problem in achieving the equilibrium but also affects the calculation of the equilibrium. Thus this is the stuff which one needs to prevent from happening.

Statically Indeterminacy Explanation:
Statically indeterminacy in a structure means that there are more unknowns (such as support reactions, member forces, etc.) than the number of equations available for equilibrium. This makes it impossible to solve for all unknowns using only equilibrium equations.
- **Less Equations Available for Equilibrium**:
In statically indeterminate structures, the number of unknowns exceeds the number of equilibrium equations that can be written. This results in a situation where not all unknowns can be determined solely through equilibrium analysis.
- **Challenges in Solving for Unknowns**:
Due to the lack of sufficient equilibrium equations, additional analysis techniques such as compatibility equations, virtual work method, or displacement methods are required to solve for all unknowns in a statically indeterminate structure.
- **Complexity of Analysis**:
Statically indeterminate structures introduce complexity in analysis as compared to statically determinate structures, where all unknowns can be solved using equilibrium equations alone. This complexity arises from the need to consider additional factors beyond equilibrium.
- **Importance of Understanding**:
Understanding statically indeterminate structures is crucial for structural engineers as it allows for the accurate analysis and design of complex structures that cannot be solved using basic equilibrium principles.
- **Engineering Applications**:
Statically indeterminate structures are commonly encountered in real-world engineering applications, such as bridges, buildings, and aircraft components. Engineers must apply advanced analytical techniques to accurately determine unknown forces and reactions in these structures.
