GK 12 Review Presentation C. J. De. Groot St. Louis Charter School
Three Units • Designing and Building File-Folder Bridges – Build a Model Truss Bridge – Test the Strength of Structural Members – Analyze and Evaluate a Truss • Hazard Mitigation Letter • Tsunami Brochure
Designing and Building File-Folder Bridges • Brief introduction to engineering – – – What is engineering? What do engineers do? What type of people are engineers? What different types of engineering exist? What things do engineers work on? Types of Engineering
Designing and Building File-Folder Bridges • Learning Objectives: Build a Model Truss Bridge – – – Identify different types of bridges Explain what a truss is Identify the major components of a truss bridge Identify types of truss bridges Explain fundamental engineering concepts: • Force, Load, Reaction, Equilibrium, Tension, Compression, Strength – Explain how a truss carries load – Explain the roles of owner, design professional, constructor, project manager – Explain how construction quality affects structural performance

Tension or Compression? 16. Truss member DK
Designing and Building File-Folder Bridges • Learning Objectives: Test the Strength of Structural Members – Calculate cross-sectional area of a member – Describe yielding, rupture, and buckling failure – Explain the factors that affect the tensile strength and compressive strength of a member – Design a testing program to determine the strength of structural members – Explain the principle of the lever and apply it – Determine the tensile strength and compressive strength of structural members experimentally – Use a computer to analyze and graph data
• Principle of the Lever – Forces must be balanced – Moment must be balanced around the fulcrum
• Tensile Strength Graph
• Compressive Strength Graph
Designing and Building File-Folder Bridges • Learning Objectives: Analyze and Evaluate a Truss – Calculate the components of a force vector – Add force vectors – Explain fundamental engineering concepts: • Free body diagram, equilibrium, structural model, symmetry, static determinacy, stability, factor of safety – Use the Method of Joints to calculate the internal force in truss members – Determine the strength of every member – Evaluate a truss to determine if it can safely carry a given load
• Add Force Vectors
• Add Force Vectors
• Add Force Vectors
• Method of Joints
Hazard Mitigation Letter • Learned about structural and nonstructural earthquake mitigation (focused on nonstructural) • Learned Mitigation Techniques for: - Computer Equipment Hot water heaters Pictures and Mirrors Bookcases/cabinets Light Fixtures Library stacks Securing heavy equipment - Gas shut-off valves Windows Flexible gas lines Chimneys/Masonry Securing heavy objects Signs/Bulletin boards
Hazard Mitigation Letter • Learned what to do before, during, and after an earthquake • Broke into two groups for “inspecting” the school • Each student was responsible to write a persuasive letter about how the school could be made safer through earthquake mitigation techniques
Tsunami Brochure • For the globalization requirement, we studied the 2004 Indian Ocean Tsunami • Students chose a particular country to focus on • Students were responsible for their own research – Amy and I provided guidance (no Wikipedia, etc. ) • Students each made a three-panel informational brochure with Microsoft Publisher – Information about tsunamis – Information about their country – Information about rebuilding in their country
