Following are the differences between statically determinate structures and statically indeterminate structures

Aspect	Statically Determinate Structures	Statically Indeterminate Structures
Equilibrium Conditions	Conditions of equilibrium are sufficient to analyze the structure.	Conditions of equilibrium are insufficient to fully analyze the structure.
Bending Moment and Shear Force	Independent of material and cross-sectional area.	Dependent on material properties and independent of cross-sectional area.
Effect of Temperature and Lack of Fit	No stresses are caused by temperature changes or lack of fit.	Stresses are induced due to temperature changes and lack of fit.
Compatibility Conditions	Compatibility of displacements is not required for analysis.	Compatibility of displacements is required in addition to equilibrium equations.
Ease of Analysis	Easier to analyze using basic equilibrium equations.	Requires additional methods (e.g., force or displacement methods) for analysis.
