Classify the following structures as statically determinate, statically indeterminate or geometrically unstable. If statically indeterminate, determine the degree of indeterminacy. \[ \begin{array}{l} r=3 n \\ 8=3 \times 3 \\ 8=9 \\ \text { unstable } \end{array} \] (2.Marks) b) (2 Marks) \[ \begin{array}{l} 6+r=2 j \\ 18=2 \times j \end{array} \]
