Prerequisite: DRF 121 .
Learning Outcomes
Upon successful completion of this course, students will be able to:

  1. Demonstrate familiarity with materials: Metal Thermoplastic Structural steel.
  2. Select appropriate weld types for given connections and apply weld symbols correctly. 
  3. Demonstrate knowledge of standards for threaded and nonthreaded fasteners. 
  4. Use tables and handbooks to find design data.
  5. Find dimensions and other data for fasteners. 
  6. Find dimensions and other data for keys and keyways. 
  7. Find V-belt and roller chain design data. 
  8. Translate design concepts into virtual and physical models, building neural links between mental concepts and physical reality and developing visualization skills.
  9. Demonstrate understanding of cam and linkage kinematics. 
  10. Demonstrate knowledge of gear geometry and gear train types. 
  11. Demonstrate comfort with quantitative thinking: Gears V-belt and roller chain drives.
