Sample subject outline - Semester 1 2013

Note: Subject outlines often change before the semester begins. Below is a sample outline.

Rationale

Engineers deal with systems that are made up of solids, liquids and gases that may work individually or in unison. All engineers need to understand the basic relationships amongst force, motion and energy, namely how energy is transformed and how it flows through such systems. This knowledge will help engineers analyse, synthesize and understand the working of various components and their characteristics that make up an engineering system. ENB130 is one of four first year units that covers such fundamental principles that engineers will use and apply in their professions.

Aims

The aim of this unit is to introduce the fundamental concepts that are applied by engineers to understand the interaction between components of an engineering system that result in motion and transmission of energy through them, using simple examples.

Objectives

On completion of this unit you should be able to:

1. Recognise and apply the basic relationships amongst force, motion and energy.
2. Solve problems (analytically and practically) involving force, motion and energy at an introductory level both individually and in teams.
3. Retrieve, evaluate, present and use relevant information to describe the behaviour of simple engineering systems.

Content

The following topics will be covered:

1. Introduction to simple Engineering Systems, Force & motion, frames of reference, types of energy


2. Motion in 1-D and 2-D, Newton's I & II Laws of motion, Conservation of momentum


3. Energy - gravitational, potential and kinetic energy, Principle of Energy Conservation, sources of energy


4. Angular motion, angular momentum and rotational KE, Torque generating systems


5. Heat Energy, Heat Capacity, specific heat and latent heat, liquid and gaseous systems in engineering


6. Thermodynamic Processes and motion-producing systems, First Law of Thermodynamics with an introduction to the second law


7. Heat Transfer Mechanisms in Engineering Systems, Conduction Principles, Fourier's Law


8. Convection - Natural & Forced, Newton's Law of Cooling, Radiation

Approaches to Teaching and Learning

Teaching Mode:
ENB130 will use a combination of lectures, tutorials and laboratory experiments with real world examples to realise the learning outcomes of the unit. The fundamental theories and principles will be introduced through lectures. Problem solving tasks of varying levels of complexity will be structured to draw out the concepts covered in the lectures. Laboratory exercises will enhance the learning experiences in this unit.

Lectures: You will attend a 2-hour lecture every week which will present the fundamental theoretical principles that govern the behaviour of different mechanical, thermal and electrical components/systems. Each theoretical concept will be introduced to the class using appropriate real world examples in the lecture.

Tutorials: You will attend a 2-hour tutorial every week which will be comprised of two aspects. The first aspect is the application of the theoretical principles introduced in the lectures to solve a range of numerical problems. Tutors will guide you in formulating appropriate solution methodologies and solve problems. The second aspect will be a brief session involving a discussion of a typical application example that relates to a succeeding lecture topic which the class will have to analyse and develop possible interpretations. This will prepare the class about what to expect in the next lecture class.

Laboratory Experiments: The class will be divided into small teams which will perform a set of laboratory experiments relevant to their real world context. Each individual will produce two reports summarising and discussing their results.

Assessment

Assessment for this unit consists of problem solving tasks throughout the semester, two reports summarising laboratory work and an exam.

Formative Assessment:
You will receive oral feedback on your progress in this unit including assessment and related activities during tutorials and discussions throughout the semester.Mode of feedback: You will receive written feedback on problem solving and project related laboratory tasks throughout the semester.

Assessment name: Problem Solving Tasks

Risk assessment statement

You will undertake lectures and 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.

You will be required to undertake practical sessions in the laboratory under the supervision of the lecturer and technical staff of the School. In any laboratory practicals you will be advised of requirements of safe and responsible behaviour and will be required to wear appropriate protective items (e.g. closed shoes or steel capped shoes).

You will undergo a health and safety induction before the commencement of the practical sessions and will be issued with a safety induction card. If you do not have a safety induction card you will be denied access to laboratories.

Disclaimer - Offer of some units is subject to viability, and information in these Unit Outlines is subject to change prior to commencement of semester.
