Overview

In this unit, you will explore the dynamics of rigid bodies and how motion, forces, and energy interact within mechanical systems. You will analyse the kinematics and kinetics of two-dimensional systems using theoretical, computational, and experimental approaches to predict and evaluate dynamic responses under varied loading conditions.

Through simulations, laboratory investigations, and practical problem-solving, you will develop the skills to model, measure, and interpret motion and force behaviour with precision and confidence. The unit fosters curiosity and analytical thinking while emphasising safe, reliable, and efficient system design. By the end of this unit, you will be able to apply dynamic principles and professional engineering methods to evaluate and communicate the behaviour of real-world mechanical systems.

Learning Outcomes

On successful completion of this unit, students will be able to:

Apply and analyse the principles of rigid-body dynamics to predict motion and force interactions of dynamic systems;
Develop and validate analytical and computational models to evaluate dynamic response under varying loads and conditions;
Design and conduct experiments to measure and interpret dynamic responses, incorporating uncertainty and error analysis; and
Articulate complex dynamic analyses and results clearly in professional engineering contexts.

Assessment

For Melbourne campuses

Assessment type: Exercise | Grade: 15%

In-class dynamics modelling exercise applying rigid-body motion and force principles to unseen problems (Individual) (45 mins)

Assessment type: Laboratory Work | Grade: 35%

Experimental investigation analysing motion and dynamic response of rigid-body systems, including measurement and data interpretation report (Individual) (1500 words)

Assessment type: Test | Grade: 50%

In-class invigilated analytical problem-solving test on rigid-body kinematics and kinetics, including energy and momentum principles (Individual) (90 mins)

Exercise: This secure in-class assessment ensures authenticity by requiring students to apply rigid-body dynamics principles to solve unseen modelling problems under supervised conditions. Real-time reasoning and unpredictable scenarios verify individual understanding and analytical skill.

Laboratory Work: Experimental investigation analysing motion, forces, and energy transfer in rigid-body systems. Students collect, analyse, and interpret motion data to evaluate system behaviour, supported by collaborative discussion and feedback.

Test: This secure invigilated test ensures authenticity by requiring students to demonstrate analytical and problem-solving skills in dynamic system modelling. Unpredictable questions and applied calculations confirm understanding and assurance of learning.
