Design of Mechanical Systems

Unit code: NEM3102 | Study level: Undergraduate

Credit points

(Generally, 1 credit = 10 hours of classes and independent study.)

Location

Footscray Park

Prerequisites

NEM2101 - Mechanical Engineering Design

NEM3203 - Stress Analysis

(Or equivalent to be determined by unit coordinator)

Overview

This unit equips students with the design and judgement skills necessary to tackle complex problems in Mechanical Engineering Design. Students will work both individually and collaboratively to design a variety of machine elements for mechanical engineering systems. Building on the foundational knowledge from NEM2101 Mechanical Engineering Design, this unit places a strong emphasis on designing components subjected to fatigue conditions. The use of Computer-Aided Design (CAD) software will facilitate the creation of solid models for mechanical elements. A real-world project will serve as the capstone for this unit, offering students a rich, authentic context to consolidate their learning and enhance their practical design skills.

Learning Outcomes

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

Apply fundamental mechanics and scientific principles to the design and selection of mechanical elements;
Identify engineering design challenges and develop effective, practical solutions;
Evaluate existing mechanical designs and generate innovative alternatives using computational methods;
Collaborate effectively within a design team to apply knowledge and skills across various contexts; and
Communicate ideas and technical knowledge clearly and professionally to diverse audiences.

Assessment

For Melbourne campuses

Assessment type: Portfolio

Grade: 10%

Compilation of mechanical design work, including drawings, calculations and reflections (1000 words) (Individual)

Assessment type: Test

Grade: 50%

In-class invigilated test on core mechanical design principles (Individual) (90 mins)

Assessment type: Project

Grade: 40%

Design Project (Report 20% & Presentation 20%) (2500 words) (Group)

Portfolio: The portfolio is continuously updated and reflects individual contributions to the design process. It will be regularly checked for originality and academic integrity. Students will compile a portfolio showcasing their mechanical design skills, including drawing submissions, calculations, and ongoing project work. This portfolio will be assessed for creativity, technical accuracy, and application of design principles.

Test: The test is invigilated, ensuring individual assessment under secure conditions. Random problem sets will be provided to assess the students’ ability to solve complex problems in real-time.

Project: Group work will be assessed based on individual contributions, with milestone checks ensuring the authenticity of the work. Presentations will involve unpredictable Q&A to validate each student’s understanding. The project will assess their ability to work collaboratively, solve complex problems, and communicate design solutions effectively. The project requires practical application of design principles and teamwork, with an emphasis on problem-solving and interaction in a team setting. Explicit evaluation of individual contributions further supports the secure assessment and assurance of each student’s achievement of learning outcomes.
