Consider the four structures shown below.

a$)$ By using appropriate calculations and$/$or sketches, compute the degree of redundancy $($or

indeterminacy$).$

b$)$ Based on your degree of redundancy calculations, suggest an appropriate analysis technique for

computing the support reactions for each structure $($if applicable$).$ Discuss your reasoning.
