Unit Description and General Aims

The objective in presenting this unit is to provide students with an in-depth study of the fundamentals of mechanics of materials and structures.

 

The subject matter covered in this unit will include: all relevant physical properties and fundamental laws governing the behaviour of materials and structures; the concepts of equilibrium and application of these to various structures; free body diagrams; forces, moments, and centres of mass; the forces of friction and rigid body dynamics; stress-strain analysis; shear force and bending moment diagrams; and, the effects of torsion.

 

Successful completion of this unit will serve as a key prerequisite for subjects involving mechanics of machines, and design of mechanical systems.

 

Learning Outcomes

 

On successful completion of this Unit, students are expected to be able to:

  1. Interpret and solve engineering problems based on the laws of mechanics and force and equilibrium concepts.

  2. Perform calculations related to mass moment of inertia.

  3. Evaluate forces of friction and the principles of rigid body dynamics.

  4. Perform stress-strain analysis and deformation calculations.

  5. Determine shear force, bending moment, and deflection in beams.

  6. Evaluate the effects of torsion in shafts and springs.

  7. Determine stresses in cylinders and spheres.
