Project Examples

Water Tank Design and Analysis for Yanacaca, Peru


Course: 22.425 - Design Machine Elements
Semester: Fall 2006
Instructor: Chris Niezrecki
Partner: Village Empowerment Peru Project

Students analyzed the mechanical components for static and dynamic loading failure and fatigue failure. Each of the five Design of Machine Elements projects were different and conducted in collaboration with a partner organization listed above. The S-L projects were reported to have engaged students’ interests and enthusiasm. The S-L projects also provided student motivation for working on the assignments. The S-L projects also provided the professor with creative problems that needed solving, versus just a classroom exercise.

Learning objectives met by the S-L project were for students to:

  • Experience the design process, including working directly with a community partners
  • The principles of mechanics and commonly used failure theories were applied to the design and analysis of machine elements subjected to static and dynamic (fatigue) load conditions.
  • Elements studied included power screws, bolts, springs, bearings, gears, lubrication, shafts, brakes, clutches, and belts. 
  • Student designs included a stress analysis or fatigue analysis that integrated recommendations
  • Write brief technical reports and incorporate drawings

Community objectives met by the S-L project:

  • Individual partners derived benefit through appropriate mechanical designs tailored to specific needs
  • The LNHP project produced reports that continue to serve as potential mechanical designs to address this ongoing community need.
