Lectures supported by problem-solving tutorials developing material covered in lectures

The required time commitment from the beginning of semester to the end of the final exam is 48 hours attendance at lectures, 48 hours of self directed learning, 3 hours of laboratory work, 40 hours completing assignments and laboratory reports and 40 hours of revising course material and preparing for the exam.

Assignments

All assignments are based on a problem-solving format. In each case a practical problem will be presented and the students will be asked to provide a solution to that problem. The problem format and difficulty are the same as the final exam. Each student’s submission will be assessed primarily on the quality of their approach to the problem. Students are required to state all assumptions used in their solutions, provide appropriate diagrams, and to follow a standard presentation procedure known as the “problem solving protocol”. Approximately 10% of the marks of each problem are awarded for fulfilling these requirements.

Laboratory

This laboratory consists of two parts. The first part is an experimental investigation of the pressure distribution over a wing using a wind tunnel. Students will be required to measure the pressure distribution and use the measured data to calculate the lift and pressure drag on the wing. The second part is an experimental investigation of a commercial pump using a pump testing rig. The students will measure the pressure rise and flow rate through the pump at a range of load conditions, sufficient to construct the pump performance curve. Students are required to submit group reports for each laboratory. Students must have submitted both reports and scored at least 35% overall to be eligible to pass the course. Further details are provided by the laboratory demonstrators.

Individual assignments are to be submitted by each student to the submissions box on Level 2, Engineering South Building. Unless students are otherwise notified, assignments must be submitted by 5.00pm exactly two weeks after each assignment is issued. Submitted assignments must be accompanied by an assessment cover sheet, available from room S116 or near the assignment submission area. Late assignments will be penalised 10% per day. Extensions for assignments will only be given in exceptional circumstances and a case for this with supporting documentation can be made in writing after a lecture or via email to the lecturer. Assignments will be assessed and returned within 2 weeks of the due date, along with a “model” solution prepared by the lecturer. There will be no opportunities for re-submission of work of unacceptable standard. Due to the large size of the class, feedback on assignments will be provided by comments on the returned assignments and general feedback given during the lectures and tutorials.
