    MSE 100 or ENSC 104, MSE 220 or ENSC 231, MSE 221 or ENSC 281. MSE 100 may be taken concurrently.



Review of stress and strain in solids, superposition, energy theorems, theories of failure, elastic and inelastic analysis of symmetrical bending, torsion of circular members, and virtual work. Adequacy assessment and synthesis of machine elements with a focus on the design process. Static failure of ductile and brittle materials, fatigue analysis of structures. Topics include the design of welds, bolted connections, springs and shafts. Solution strategies include both analytical and finite element methods. Students with credit for ENSC 382 may not take MSE 320 for further credit.


After completing this course, students will be able to:

  • apply appropriate advanced static failure theories to predict part failure under general loading
  • analyze parts under general loading to predict fatigue failure
  • qualitatively identify fatigue failure progression from fracture surface inspection
  • design gearbox housings
  • specify appropriate couplers for transmission connections
  • perform detailed design of shafting including locating features
  • identify spur, helical, bevel and worm gear variants
  • design spur and helical gear teeth for a given set of transmission specifications
  • select and analyze rolling element bearings suitable for a given application
  • specify required fasteners and torque specifications to guard against axial and shear failure and joint separation
  • design weld details for given static and fatigue loading


  • Assignments 15%
  • Midterm 20%
  • Labs 10%
  • Final Exam 35%
  • Final Project 20%


Tutorial sessions will be used as working sessions to reinforce concepts and tools, for general course material review and assistance, and to catch up on lecture materials if needed.


It is important to familiarize yourself with the policies and guidelines pertaining to students at SFU, including but not limited to the following:

Registrar Notes:


SFU’s Academic Integrity website http://www.sfu.ca/students/academicintegrity.html is filled with information on what is meant by academic dishonesty, where you can find resources to help with your studies and the consequences of cheating. Check out the site for more information and videos that help explain the issues in plain English.

Each student is responsible for his or her conduct as it affects the university community. Academic dishonesty, in whatever form, is ultimately destructive of the values of the university. Furthermore, it is unfair and discouraging to the majority of students who pursue their studies honestly. Scholarly integrity is required of all members of the university. http://www.sfu.ca/policies/gazette/student/s10-01.html
