Educational aims

This topic aims to give students an understanding of the basic statics concepts associated with engineering mechanics and structures.

Expected learning outcomes
On completion of this topic you will be expected to be able to:

  1. Develop and employ principles of Statics in solving problems
  2. Analyse complex three dimensional trusses, frames and machines
  3. Learn how to determine centroids and moment of inertias and how to find resultant of distributed loadings
  4. Understand concepts of stress, strain and mechanical properties of materials
  5. Analyse axial, torsional, bending, transverse stresses and their combinations in structures and machine components
  6. Understand torsion in non-circular shafts
  7. Calculate in-plane stresses and strains, their orientations and transformations through Mohr's circle, and calculate principal stresses and strains
  8. Develop methods for designing beams to resist both bending and shear loads; prismatic and fully stressed beam designs
  9. Apply research methods to quantitatively understand the latest theoretical advancements of a selection of concepts in mechanics and structures

Key dates and timetable

(1), (2)

Each class is numbered in brackets.
Where more than one class is offered, students normally attend only one.

Classes are held weekly unless otherwise indicated.


If you are enrolled for this topic, but all classes for one of the activities (eg tutorials) are full,
contact your College Office for assistance. Full classes frequently occur near the start of semester.

Students may still enrol in topics with full classes as more places will be made available as needed.

If this padlock appears next to an activity name (eg Lecture), then class registration is closed for this activity.

Class registration normally closes at the end of week 2 of each semester.

Classes in a stream are grouped so that the same students attend all classes in that stream.
Registration in the stream will result in registration in all classes.
  Unless otherwise advised, classes are not held during semester breaks or on public holidays.
