The method consists in (i) releasing constraints until the system is statically determinate (basic system (BS)) and (ii) introducing redundant variables (RV) corresponding to each released constraint. (Ref: Chapter 10) For determinate structures, the force method allows us to find internal forces (using equilibrium i.
