Statically indeterminate equation

WebStatically Determinate Structures • Reactions and internal forces can be determined solely from free-body diagrams and equations of equilibrium. • Results are independent of the … WebEssentially, a problem in statically indeterminate if there are more unknown variables then there are equations you can use to solve for the unknowns. This means it cannot be solved using equilibrium equations alone. You would need to simplify the problem or make as assumption for it to be solved.
