Description This module builds upon the manufacturing skills and competences from the semester 1 Materials and Process Technology module. The module introduces the students to the fundamental laws of mechanics and how these are applied to solve mechanical system based problems. Students will be exposed to SI units of measurement and to scientific experimentation to demonstrate relevant principles. Acquired knowledge and skills will underpin further technological enquiry where the treatment of the module's theoretical content will enable the student to engage in the informed design and realisation of a mechanical system. The student will be supported and guided through the engineering design process, where engagement with the sequencing and management of the “design and make” phases of a technological project will be highlighted and critiqued. The module delivery is designed to ensure that the student teacher acquires the appropriate level of subject content knowledge in line with: • Strand 1; Principles and Practices, of the Junior Cycle Applied Technology subject specification and • Strand 1; Processes and Principles of the Junior Cycle Engineering subject specification. Particular emphasis will be placed on the safe operation of machine tools, in line with standard operating procedures. This will include consideration of how best to effectively maintain a machine tool in the workshop environment. This module will be delivered through classroom tutorials and engineering workshop sessions. Classroom tutorials will deliver theoretical content whilst being interactive and engaging students, providing time for exploration of the theoretical content and problem-solving through pair work, small group discussions, and consideration of fundamental concepts such as; mechanical design, engineering mechanics, machine processing techniques, project planning and implementation, geometric dimensions and tolerances, manufacturing sequences and technological design considerations. Tutorials will also provide the opportunity for students to develop skills associated with high quality working drawings to include GD&T. Computer software will be utilised where appropriate to produce CAD drawings, produce project reports and conduct research to inform design and manufacture decisions. Practical engineering workshop labs will see students develop processing skills with a range of engineering materials. Emphasis will be placed on machining processes with a focus on precision, accuracy and efficiency with a constant commitment to health and safety and best practices in line with standard operating procedures. These processes and procedures will be executed to manufacture a mechanical system that the students will design as part of a team in response to an engineering design brief. | |||||||||||||||||||||||||||||||||||||||||

Learning Outcomes 1. Recognise the importance of project oriented learning activities in the technology education discipline and value the process of technological project work for the achievement of the goals of technology education. 2. Evaluate and reflect upon the process and product elements of project work in relation to health and safety, and compliance with defined engineering standards. 3. Analyse and solve mechanics problems using suitable mathematical formulae and techniques. 4. Define and explain fundamental mechanics terms and concepts pertinent to topics such as; work power and energy, stress and strain, linear and angular motion and simple machines. 5. Carry out theoretical mechanics calculations to inform the design of a mechanical system based project. 6. Create detailed engineering drawings of final project design to include dimensional and geometric tolerances and required annotations for manufacture. 7. Produce a report to outline the completed stages of the engineering design process for a mechanical system based project. 8. Operate engineering workshop machine tools to produce engineering components to required dimensional and geometric tolerances. 9. Conduct risk assessments prior to undertaking all machining operations and carry out all processes in line with standard operating procedures with particular emphasis being paid to health and safety considerations. 10. Assemble manufactured engineering components utilising standard engineering components such as bearings, pins, springs, shafts and appropriate mechanical fasteners to ensure the efficient operation of a mechanical system based project. | |||||||||||||||||||||||||||||||||||||||||
