In the force method, what is done to form the primary structure of a statically indeterminate system?
Correct answer: C. The redundant forces are released
- A. Every support is converted into a fixed support
- B. All external loads are removed
- C. The redundant forces are released
- D. The member stiffnesses are made equal
Explanation
The selected redundants are removed or released so that the remaining structure becomes stable and statically determinate. Compatibility equations are then used to restore the released restraints and determine the redundant forces.

The more specific you are, the faster it gets fixed. A source beats an opinion.

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.
