WebApr 26, 2024 · External indeterminacy is related to how stably the support system exerts reaction components. It can be calculated as the number of external reaction components in excess of the number of equilibrium equations required for the static determinacy or minimum number of reaction components required for stability. WebSince r=3+e_{c}, the structure is statically determinate externally. Alternative Method. f_{i}=6, n_{r}=4, r+f_{i}=6+6=12, and 3 n_{r}=3(4)=12. Because r+f_{i}=3 n_{r}, the structure is statically determinate externally. (f) This frame is internally unstable with r=4 and e_{c}=1. Since r=3+e_{c}, the frame is statically determinate externally.
