The kinematic indeterminacy of a structure is the number of
Correct answer: D. Independent displacement components that must be determined
- A. Members that carry axial force only
- B. Independent support reactions that must be calculated
- C. Unknown internal forces after equilibrium is applied
- D. Independent displacement components that must be determined
Explanation
Kinematic indeterminacy counts the independent joint translations and rotations remaining after support restraints are considered. It differs from static indeterminacy, which counts the excess force unknowns beyond the available equilibrium equations.

About Structural Analysis
Structural analysis determines how beams, frames, trusses and arches carry loads through reactions, shear forces, bending moments, axial forces and deflections. It covers free-body diagrams, equilibrium equations, determinacy, influence lines and methods such as slope deflection, moment distribution and virtual work, while distinguishing analysis of a structure from its design.
