Question 2.4: Classify each of the pin-connected structures shown in Fig. ...

Classify each of the pin-connected structures shown in Fig. 2-19 (\mathrm{a}) through 2-19 (\mathrm{d}) as statically determinate or statically indeterminate. If statically indeterminate, report the number of degrees of indeterminacy. The structures are subjected to arbitrary external loadings that are assumed to be known and can act anywhere on the structures.
