AI Thread Summary
To determine the degree of static indeterminacy in an arbitrary frame, one must sum the internal and external forces and moments. The number of equilibrium equations available is denoted as M, while the number of unknowns is represented as N. The formula for static indeterminacy is calculated as M minus N. A positive result indicates static indeterminacy, while a zero or negative result suggests a determinate structure. Understanding these calculations is essential for analyzing structural stability.

Sorry this isn't for a particular question, just wondering if anyone knows how to determine degree of static indeterminacy (or degrees of freedom) in an arbritary frame?

Any help greatlly appreciated thanks.

Sum the internal and external forces and moments.

Count the number of equations - M
Count the number of unknowns - N

Static Indeterminacy = M-N
