Sample subject outline - Semester 1 2013
Note: Subject outlines often change before the semester begins. Below is a sample outline.
Rationale
Mechanical engineers are required to have a sound knowledge in motions of particles and rigid bodies which involves displacement, velocity and acceleration in kinematic analysis; and determination of dynamic forces acting on rigid bodies. These forces play an essential part in the design and production of machines, such as motor vehicles, aircrafts and robotic devices. This unit is offered in the second year to provide the background knowledge to a string of units in mechanical engineering, such as machine design, noise and vibration and mechanics of machines.
Aims
The aims of the unit are to provide you with (a) a basic understanding of kinetics and kinematics of particles and rigid bodies; (b) analytical skills in formulating and solving problems involving motion, (c) an introduction to vibration and (d) sufficient mechanics background in the later part of the course in project work and instrumentation.
Objectives
On completion of this unit, you will be able to:
1. Apply fundamental principles of kinematics and kinetics in formulating and solving dynamics problems for particles, rigid bodies and mechanical vibrations
2. Analyse basic mechanical components and mechanisms.
Content
The following topics will be covered in this unit:
- Review of coordinate systems (rectangular, n-t and polar)
- Particles kinematic, force, mass, acceleration
- Particle kinetics, work and energy
- Particle kinetics, impulse and momentum; impact relative motion,
- Particle kinetics, kinematics systems of particles
- Kinetics of systems of particles
- Rigid body kinematics
- Rigid body kinetics; Motion relative to rotating axes,
- Rigid body kinetics - translation and rotation
- Introduction to single-degree-of-freedom systems
Approaches to Teaching and Learning
Teaching Mode
Total hours per week: 4
Lectures: 2 hrs
Tutorial: 1 hr
Computer Labs: 2 x 1 hr
Computer Lab 1 - 2D simulation (rigid body kinematics)
Computer Lab 2 - 2D simulation (rigid body kinetics)
Computer group project
The unit will be conducted by means of conventional lecture, tutorial and interactive software. The formal lecture and tutorial will be supplemented with computer based education (CBE). The CBE session is primarily aimed at enhancing the theoretical knowledge learned in class by giving you the resources to put theory into practice at your own pace. The lecture will be conducted with references to fundamental basic concepts and relevant 'real-life' engineering problems, interactive tutorials with provision for individual and team work participation and emphasis on learning by formulating and solving problems. Team participation in assessment tasks will form part of the learning process and feedback will be provided to improve your understanding and application of the unit.
Assessment
The overall assessment of the unit consists of computer laboratory practicals/project (including a group report), weekly problem solving tasks and a final written examination.You will receive formative oral feedback on prescribed tutorial problems and your progress in the unit throughout tutorial sessions. You will receive written feedback on your computer practicals and report and problem solving tasks and formative feedback on preparation for the final exam.

Assessment name:
Problem Solving Task
Description:
You will need to employ Interactive Physics Software to develop simulation models for assigned dynamics problems. You also need to develop theoretical solutions for these problems and compare them with those obtained from computer simulations. This assessment will include individual and group computer labs. You will be required to submit these comparisons periodically as requested by the lecturer to receive feedback.

Risk assessment statement
Students in this unit will undertake lectures and/or tutorials in the traditional classrooms and lecture theatres. As such, there are no extraordinary workplace health and safety issues associated with these components of the unit. Students in this unit, however, may be required to undertake lecturer-led individual site visits. A safety induction course is provided by the school in the first week of the first semester. Students who do not have, or cannot produce a safety induction card will not be allowed to undertake the site visits.
Students will be required to undertake computer simulation sessions in the computer laboratory under the supervision of staff of the School. The School's occupational health and safety policies and procedures will apply to these sessions. In any laboratory practicals students will be advised of requirements of safe and responsible behaviour. Students who do not follow legitimate instructions or who endanger the safety of others or do not act in accordance with the requirements of the Workplace Health and Safety Act will be required to leave the session.
