Option 3 : Kinematic indeterminacy

Force method is useful when D_s < D_k

Displacement method is useful when D_k < D_s

Force Method	Displacement Method / Stiffness method
1. Unknowns are taken redundant forces/reactions.	1. Unknowns are taken displacement
2. To find unknown forces or redundant compatibility equations are written.	2. To find unknown displacement joint Equilibrium conditions are written.
3. The number of compatibility equations needed is equal to degree of static indeterminacy.	3. The number of equilibrium conditions needed is equal to degree of kinematic indeterminacy.
