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 subject 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 subject 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.

Learning Outcomes

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

  13. Calculate bending stresses and deflections for beams
  14. Calculate transverse shear stresses in beams
  15. Calculate strain energy in axially loaded columns, shafts under torsion and beams under bending
  16. Predict stress, strain and deformation as a result of an impact loading
  17. Use energy methods to calculate the deflection of a truss
