10.1. Introduction

Try these first

1. 1.

   Define a statically indeterminate structure.

   Hint

   Think about the balance of forces.

2. 2.

   What is equilibrium in terms of structures?

   Hint

   Consider what would happen if they are not balanced.

3. 3.

   What defines a statically indeterminate structure?

   • More equations than unknowns
   • Equal equations and unknowns
   • More unknowns than equations

   Hint

   Focus on the balance of information.

4. 4.

   Is redundancy in statically indeterminate structures beneficial?

   • True
   • False

   Hint

   Think of backup plans!

5. 5.

   Analyze a simple braced frame structure. Identify the redundancy and how it impacts the structure's ability to distribute loads.

   Hint

   Consider creating a free-body diagram for clarity.

6. 6.

   Using the flexibility method, derive the internal forces in a cable-supported structure with known displacements.

   Hint

   Recall how force-displacement relations are established!
