Challenge Problems
Push your limits with advanced challenges
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.
💡 Hint: Remember to sketch the truss to visualize the member placement.
Analyze a given truss drawing that shows forces acting on the joints. Determine if it is stable, indeterminate, or determinate. List your reasoning.
💡 Hint: Count all joints, members, and reactions to evaluate statics.
