1. 1.

   What is a statically indeterminate structure?

   Hint

   Consider the relationship between unknowns and equations.

2. 2.

   Name the two main methods of analyzing statically indeterminate structures.

   Hint

   Think of F and S in the context of structural analysis.

3. 3.

   What is a statically indeterminate structure?

   • It has more equations than unknowns.
   • There are more unknowns than equations.
   • It only has internal forces.

   Hint

   Focus on the relationship between known and unknown variables.

4. 4.

   True or False: The flexibility method relates applied forces to displacements.

   • True
   • False

   Hint

   Recall the purpose of the flexibility method.

5. 5.

   Given a structure with three supports, determine whether it is statically determinate or indeterminate and justify your answer with calculations.

   Hint

   Use the equilibrium equations framework for analysis.

6. 6.

   Using the flexibility method, analyze the internal stresses of a simple truss under a given load and explain the significance.

   Hint

   Remember to consider the material properties in your calculations.
