Paper Description

Edit Paper Description Content

This paper covers the dynamics of both particles and rigid bodies. It also includes the fundamentals of vibrations

It deals with the concepts of forces, moments, equilibrium, free body diagrams, Newton’s laws, work, energy, impulse, momentum and fundamental vibration systems. The theory is applied to the design of mechanical components.

Learning Outcomes

Edit Learning Outcomes Content

Students who successfully complete the course should be able to:

  • apply the basic principles of vector mechanics to establish the relationship between displacements, velocities and accelerations of particles, systems of particles and mechanisms subject to constraints
    Linked to the following assessments:
  • calculate the centripetal and Coriolis acceleration components of motion
    Linked to the following assessments:
  • judge the most appropriate method of dynamic analysis of common mechanical systems using either relative coordinates or absolute coordinates
    Linked to the following assessments:
  • relate the velocities and accelerations of mechanisms subject to constraints using geometry, trigonometry, the differentiation method, and where applicable, the concept of instantaneous centre (in the case of velocities)
    Linked to the following assessments:
  • apply Newton’s laws of motion including force-acceleration, moment-angular acceleration, impulse-momentum, angular impulse-angular momentum equations, the principle of conservation of energy, and work-energy equation
    Linked to the following assessments:
  • apply the principles of kinetics and kinematics to simple mechanical systems to relate the forces and moments to the displacements, velocities and accelerations
    Linked to the following assessments:
  • apply the principles of kinetics and kinematics to problems involving fluid flow (e.g. impulse-turbine or centrifugal pump)
    Linked to the following assessments:
  • apply Newton’s law of motion and analyse single DOF and two DOF free and force vibration systems.
    Linked to the following assessments:
  • apply the principles of kinematics and dynamics to practical mechanisms in a laboratory context

Assessment Components

Edit Assessments Content

The internal assessment/exam ratio (as stated in the University Calendar) is 50:50. There is no final exam. The final exam makes up 50% of the overall mark.

The internal assessment/exam ratio (as stated in the University Calendar) is 50:50 or 0:0, whichever is more favourable for the student. The final exam makes up either 50% or 0% of the overall mark.
