Wyatt Collins determinacy is all about number of unknowns vs. number of equations. external indeterminacy = means you have more support reactions than eqns. internal indeterminacy means that there is not enough eqns to solve for internal member forces/moments even though you could get reactions.
you're so clear thank you it is so helpful
Can you explain the difference between external and internal indeterminacy, both conceptually and mathematically, please.

That makes sense, conceptually. Thank you.
