Question 1.
Define a statically determinate truss.
Show hintHide hint
Think about how we can analyze forces using equilibrium.
Question 2.
What does it mean if a truss is statically indeterminate?
Show hintHide hint
Consider the importance of reactions and unknowns.
3Question 3.
What does a statically determinate truss allow for?
- Only tension forces
- Only compression forces
- Forces calculated from statics
Show hintHide hint
Think about the relationship of forces in a truss.
4Question 4.
True or False: An unstable truss will not maintain its shape under load.
- True
- False
Show hintHide hint
Consider the definition of a stable structure.
Question 5.
Design a truss bridge with a specific load requirement, ensuring it is both statically determinate and stable. Consider the number of joints and members carefully.
Show hintHide hint
Remember to sketch the truss to visualize the member placement.
Question 6.
Analyze a given truss drawing that shows forces acting on the joints. Determine if it is stable, indeterminate, or determinate. List your reasoning.
Show hintHide hint
Count all joints, members, and reactions to evaluate statics.
