3 cards from this section. Quick, good the night before a test.
Define force in the context of structural analysis.
Think about what pushes or pulls an object.
What does displacement measure?
Look for a term referring to movement.
What does the stiffness method primarily focus on?
Look at the method's name.
True or False: Force-displacement relations only apply to beams.
Consider other types of structures.
A simply supported beam is subjected to a uniform load. Derive the expression for the maximum deflection using the stiffness method.
Watch for boundary conditions that will shape your outcome.
Analyze a 3D frame using stiffness relations, showing how forces affect displacements at various joints.
Break down the components and tackle one joint at a time.
