This online course will enable you to gain an understanding of the fundamental principles and laws of mechanics.

The course will cover the following:

  • FBD for beams with point and uniformly distributed loads
  • Shear Force and Bending Moment diagrams.
  • Basic mechanical theory as applied to 2-dimensional systems
  • Systems of static loads and simple frameworks
  • Centroid, centre of gravity and moment of inertia
  • Bending stresses. Selection of sections from tables. Torsional shear stresses in solid and hollow shafts. Polar second moments of area.
  • Work and energy, linear and angular momentum
  • Forces and linear and angular motion

Learners who successfully complete this online course will be able to:

  • Analyse basic theory, principles and applications of forces and moments in mechanics and engineering.
  • Calculate indirect stresses (bending and torsion) in mechanical components and select appropriate sections from standard tables.
  • Analyse the forces, moments, torques, work and energy, including conservation of energy, resulting from linear acceleration, rotational acceleration and centripetal acceleration.
  • Apply the basic principles of fluid analysis.

Course update

This course replaced DE4302 – Mechanics; completion of DE4302 – Mechanics will fulfil the same prerequisite requirements as DE5305 – Mechanics.
