Before you get started, print out this Agenda and the Learning Log. The Agenda is your management and progress assessment tool and it covers this entire module of study. The Learning Log is a list of key terms and concepts you must understand. Complete it as you proceed through this module. Start at sub-task “a” and proceed through this portion of the checklist. Once you have completed the Pre-Test, go directly to Task 2. This and the remaining sections form the instructional meat of this module. While completing these tasks, you will learn the content and complete assignments that you will be tested over so study these lessons carefully. Once you have complete all of the tasks return to this section. Once you have completed all the Tasks and the Learning Log then you must finish the module Practicum and Exam. Please note that you must complete all assigned Subtasks to receive credit for the complete Task. There is no partial credit. Please remember that you are also required to pass the module Practicum and Exam before moving on to the next module.
Upon completion of this module, students will be able to identify key facts regarding materials and structural design. Students will recognize shapes of structures and the materials used to provide greater strength and functionality. They will also study and apply fastening and fabrication techniques as they evaluate their design through destructive testing and analysis. Students will identify the forces acting upon structures in an effort to maximize the efficiency of their design. Finally, students will apply this knowledge to the construction of both a virtual and physical model.

When students have completed this task, they will have the knowledge and skills to determine the origin and purpose of many materials used to make everyday products. Students will also study and categorize sample materials by characteristic and properties of a variety of materials used in manufacturing. Students will determine the characteristics of materials used in the manufacturing process. Students will:
  • differentiate between primary and secondary manufacturing.
  • describe the types of materials used in manufacturing.
  • identify properties of materials.
  • classify manufacturing materials.
  • determine what to consider when developing a new device.

7. / Designing and Analyzing Virtual Structures / ( / / ) / ( / / )
Students will use the West Point Bridge Designer(WPBD) program to create a structural model of a truss bridge. Engineers apply physics and mathematics to virtual modelsto predict how a structure will behave once it is actually constructed. The WPBD simulation software allows students to identify the forces of tension and compression as they act upon the members of the truss structure. The goal is to create an efficient model bridge, which means a bridge that will support the required load while meeting budgetary constraints. Students will use mathematical modeling to make changes in their design (including using different materials) to extrapolate the characteristics affecting bridge efficiency. The initial goal is for students to design a successful bridge. Later, students can compete to see who can design the most efficient bridge design.
