10.1.1.1. Equilibrium

Try these first

1. 1.

   What is a statically indeterminate structure?

   Hint

   Think about the balance of forces in a structure.

2. 2.

   Name one advantage of statically indeterminate structures.

   Hint

   Consider the failure of support.

3. 3.

   What term describes a structure with more unknown forces than equations of equilibrium?

   • Statically Determinate
   • Statically Indeterminate
   • Equilibrium

   Hint

   Think about how many forces can be calculated.

4. 4.

   True or False: Statically indeterminate structures are more simple to analyze.

   • True
   • False

   Hint

   Consider how redundancy affects complexity.

5. 5.

   Given a cantilever beam of length L subjected to a varying load, how would you determine the deflection at the free end?

   Hint

   Consider using integration over the load distribution.

6. 6.

   Explain how temperature changes can affect the performance of statically indeterminate structures.

   Hint

   Think about how materials react under thermal expansion.
