Editing Statically indeterminate (section)

{{Short description|When a structure's static equilibrium equations have no unique solution}}
In [[statics]] and [[structural mechanics]], a structure is '''statically indeterminate''' when the [[Mechanical equilibrium|equilibrium]] equations{{snd}} force and moment equilibrium conditions{{snd}} are insufficient for determining the [[internal forces]] and [[Reaction (physics)|reactions]] on that structure.<ref>{{Cite book |title=Hyperstatic structures: an introduction to the theory of statically indeterminate structures |last=Matheson |first=James Adam Louis |date=1971 |publisher=Butterworths |isbn=0408701749 |edition=2nd |location=London |oclc=257600 |author-link=Louis Matheson}}</ref><ref name=":0">{{Cite book |title=Structural and stress analysis |last=Megson |first=Thomas Henry Gordon |publisher=Elsevier |year=2014 |isbn=9780080999364 |edition=Third |location=Amsterdam |pages=489–570 |chapter=Analysis of statically indeterminate structures |oclc=873568410}}</ref>
