12.3.1. Force-Displacement Relations

Try these first

1. 1.

   Define force in the context of structural analysis.

   Hint

   Think about what pushes or pulls an object.

2. 2.

   What does displacement measure?

   Hint

   Look for a term referring to movement.

3. 3.

   What does the stiffness method primarily focus on?

   • Displacements
   • Forces
   • Both equally

   Hint

   Look at the method's name.

4. 4.

   True or False: Force-displacement relations only apply to beams.

   • True
   • False

   Hint

   Consider other types of structures.

5. 5.

   A simply supported beam is subjected to a uniform load. Derive the expression for the maximum deflection using the stiffness method.

   Hint

   Watch for boundary conditions that will shape your outcome.

6. 6.

   Analyze a 3D frame using stiffness relations, showing how forces affect displacements at various joints.

   Hint

   Break down the components and tackle one joint at a time.
