2 cards from this section. Quick, good the night before a test.
What is a statically indeterminate structure?
Think about how many equations you can write for forces versus how many forces there are.
Why is equilibrium important?
Consider what happens if these forces are not balanced.
What is the defining characteristic of a statically indeterminate structure?
Think about the balance of forces.
True or False: Compatibility of displacements means members in a structure can have gaps.
Trust your understanding of connected structural components.
A two-span beam is subjected to a central load. Derive the internal force distribution and plot the stress-strain relations.
Balance the forces and consider the moments at the supports.
Analyze a frame structure under asymmetric loads and assess how redundancy aids stability.
Use virtual methods to visualize how the frame reacts to loads.
