Determining if the Electric Pylon is Statically Indeterminate
The electric pylon structure is declared to have 46 global nodes and 91 elements. Each element contains two nodes supporting four unknown forces. There are three equations, $$\Sigma{\boldsymbol{F_{x}=0}}$$, $$\Sigma{\boldsymbol{F_{y}=0}}$$ and $$\Sigma{\boldsymbol{M=0}}$$. You can't entirely know the vector sum of the components to compute the shear stress across the face of the cross section of the nodes. The solution set is infinite because it has more unknowns than equations. The electric pylon structure is therefore statically indeterminate.
