Statically Determinate Number of rigid body number of reactions Degrees of Freedom = 3 D of F as before, but now 3 reactions Implication Can determine reactions and internal forces purely from Equilibrium considerations 3. Statically Indeterminate Number of rigid body Degrees of freedom < Number of reactions 4 Reactions, 3 D o F (as before) Implication Cannot determine reactions and internal forces from equilibrium but also need to include deformation of the structure  constitutive relations. Material does make a difference for internal and external reactions. (see block 3)...
