Educational aims
This topic gives students an understanding of the basic statics concepts associated with engineering mechanics and structures.
Expected learning outcomes
At the completion of this topic, students are expected to be able to:

  1. Develop and employ principles of Statics in solving problems
  2. Learn how to determine centroids and moment of inertias and how to find resultant of distributed loadings
  3. Understand concepts of stress, strain and mechanical properties of materials
  4. Analyse axial, torsional, bending, transverse stresses and their combinations in structures and machine components
  5. Calculate in-plane stresses and strains, their orientations and transformations through Mohr's circle, and calculate principal stresses and strains
  6. Develop methods for designing beams to resist both bending and shear loads; prismatic and fully stressed beam designs
