Statically determinate stress systems; stress – strain relations. Bending of beams: stress – moment and moment – curvature relations; beam deflections; buckling of struts. Shear in joints, couplings, beams and circular shafts. General analysis of plane stress. Introduction to failure criteria by yield and fracture. Safety factors. Prerequisite: ENGGEN 121 or 150

Further notes

The purpose of the course is to provide a foundation to the principles involved in the design of load carrying devices where the design criterion is either yielding or stiffness. Complex combined (axial, bending, shear, torsion) loading situations are addressed.

The final exam will contain SIX questions and students will be instructed to attempt ANY FIVE of the six questions. The exam will be closed book, using restricted calculators.
Length: 3 hours.
* Only the first FIVE questions that you answer will be marked.

Lab journals (two at 5% each) 10%
Tests (three at 10% each) 30%
Final exam 60%

Students are urged to discuss privately any impairment-related requirements face-to-face and/or in written form with the course convenor/lecturer and/or tutor.

No description given

The University of Auckland will not tolerate cheating, or assisting others to cheat, and views cheating in coursework as a serious academic offence. The work that a student submits for grading must be the student's own work, reflecting his or her learning. Where work from other sources is used, it must be properly acknowledged and referenced. This requirement also applies to sources on the world-wide web. A student's assessed work may be reviewed against electronic source material using computerised detection mechanisms. Upon reasonable request, students may be required to provide an electronic version of their work for computerised review.

All students enrolled at the University of Auckland are required to complete a compulsory Academic Integrity course, usually in their first semester/year of enrolment. The University of Auckland’s full guidelines on procedures and penalties for academic dishonesty are available here.
