      Office Hours:       MW 4:50-6p  in 315 Spencer Lab, or in 124 Worrilow Hall by appointment. 


      Shop and Trips:   Additional times in the Student  Shop and for field trips will be scheduled during the semester.



The primary objective of this course is to understand how engineering design uses the many principles learned in previous math, physics and engineering technology courses and to begin to learn how these principles are applied to provide design solutions. The emphasis in this course is on machine design: the design and creation of devices that consist of interrelated components used to modify force and/or motion. Along with traditional "one-answer" type of problems, the students will be presented with more open ended design projects.

Two types of design are addressed in this course:  system design through a semester long design project; and detailed design, which is only one part of the entire design process. System design will be accomplished through an industry sponsored project.  In detailed design, the general concept, application and basic outline of the required device have already been designed.  In this course, the objective us usually not to invent a new device but rather to define the shape, size and material of a particular machine element such that it will not fail under the expected load and operational conditions. The focus in this course is primarily on the stress-life approach to develop components that will not fail under the anticipated life and load requirements.

By the end of the course, students will be able to:

1)  quantify the statistical meaning of tolerances

2)  for a particular sub-set of machine elements and a given problem:

  • define failure,

  • decide on an appropriate failure model and
  • design an appropriate machine element using:
    • allowable load (under the given operating conditions) and
    • required element life; and
    • manufacturing considerations

3)  apply those same concepts to solve more open-ended design problems.
