Static indeterminancy
Figure 4.50 Hartsuijker & Welleman (2006)
A distinction can be made whether or not equilibrium relations are enough to solve:
- support reactions (external static indeterminancy)
- section forces (internal static indeterminancy)
These two categories are treated together in chapter 4.5.2 and 4.5.3 of the book Engineering Mechanics Volume 1 Hartsuijker & Welleman, 2006.
For truss structures, the analysis is simplified as shown in chapter 9.2.2 of the book Engineering Mechanics Volume 1 Hartsuijker & Welleman, 2006.
