3 cards from this section. Quick, good the night before a test.
List the main assumptions used in truss analysis.
Think about the conditions we consider in real-life structures.
Define a statically determinate truss.
What does it mean if we can solve a problem directly from static equations?
What is the main characteristic of a truss?
Consider the definitions we discussed in class.
True or False: A Howe truss design has its diagonals primarily in tension.
Remember the stress distribution of different truss types.
Analyze a complex truss structure. Given specific loads at different joints, find the internal forces using the method of joints, detailing each step of your approach.
Focus on one joint at a time and ensure all forces acting on it are accounted for.
Design a simple truss for a small bridge with specified length and load capacity. Discuss the choice of truss type (like Pratt or Howe) based on material properties.
Consider weight distribution and the load types usual in bridge applications.
