WebIndeterminate structures cannot be solved using conditions of equilibrium because ( H ≠ 0; V ≠ 0; M ≠ 0). Additional conditions are required for solving such structures. 4. Define degree of indeterminacy. The excess number of reactions that make a structure indeterminate is called degree of Indeterminacy. WebClassify each of the beams shown below as statically determinate or statically indeterminate. If statically indeterminate, report the number of degrees of indeterminacy. The beams are subjected to external loadings that are assumed to be known and can act anywhere on the beams. hinge hinge
