Description Mechanics of Materials is the study of the stresses and deformation of a body made of any elastic solid material and how these are related to the body's shape and the load applied to it. This unit looks at how and why structural components including bars and beams deform and break. It concentrates on how these are affected by the geometry of the body and loading. Types of loadings considered include normal loads, torsional loads and bending loads. The main objective of the unit is to introduce students to the aspects of stress, strain and internal force development in the components and the methods to determine the deformation and deflections of the components. Energy methods and impact loadings are also considered.Offerings of alternate units are dependent on there being sufficient student enrolment numbers. If enrolments are low, the College may cancel delivery of the alternate unit.

Learning Outcomes

On successful completion of this subject, students should be able to:
  1. Predict stress, strain and deformation in an axially loaded member.
  2. Calculate support reactions in statically indeterminate an axially loaded member
  3. Represent a general traction as stresses
  4. Represent a general displacement as strains
  5. Predict stress and angle of twist in a circular shaft undergoing torsion
  6. Construct bending moment and shear force diagrams, for beams carrying point forces, distributed forces and couples
  7. Calculate bending stresses and deflections for beams
  8. Calculate transverse shear stresses in beams
  9. Calculate strain energy in axially loaded columns, shafts under torsion and beams under bending
  10. Predict stress, strain and deformation as a result of an impact loading
  11. Use energy methods to calculate the deflection of a truss
  12. Predict the buckling of columns
  13. Observe, analyse and document the measurements in the real world and use them to verify the theory presented in the lectures.
