WARNING: This unit version is currently being edited and is subject to change!

1. INTRODUCTIONThis unit of study aims to teach: Dynamics of Rigid Bodies: Analysis of Planar mechanisms; Kinematics of rigid bodies; Kinetics of rigid bodies. Students will also develop their skills in: how to model and analyse dynamic systems and the application of theory to real systems through practical/ laboratory sessions.

At the end of this unit students will have developed skills in modelling and analysing planar mechanisms and rigid body dynamic systems.

Course content will include planar mechanisms, linkages, mobility; instant centres of rotation, Kennedy's theorem; velocity and acceleration polygons; kinematics of rigid bodies, frames of reference, velocity and acceleration, rotating frame of reference, relative velocity and acceleration, gyroscopic acceleration; kinetics of rigid bodies, linear momentum and Euler's first law; angular momentum and Euler's second law; centre of mass; moments of inertia, parallel axis and parallel plane theorems, principal axes and principal moments of inertia, rotation about an axis; impulse and momentum; work and energy, kinetic and potential energies; applications to orbital and gyroscopic motion; introduction to Lagrangian methods.

ASSESSMENT GRADING

Final grades in this unit are awarded at levels of HD (High Distinction), D (Distinction), CR (Credit), P (Pass) and F (Fail) as defined by Academic Board Resolutions: Assessment and Examination of Coursework. Details of Academic Board Resolutions are available on the University`s Policy website at http:// www.usyd.edu.au/ ab/ policies/ Assess_Exam_Coursework.pdf Standards for grades in individual assessment tasks and the summative method for obtaining a final mark in the unit will be set out in a marking guide supplied by the unit coordinator.

4. ATTRIBUTES DEVELOPEDAttributes listed here represent the course goals designated for this unit. The list below describes how these attributes are developed through practice in the unit. See Learning Outcomes and Assessment sections above for details of how these attributes are assessed.

Attribute MethodDesign Ability to realistical model an engineering situation and apply a few fundamental,

well understood principles to its solution.

Maths/ Science Methods & Tools Essential knowledge in the fields of kinematics and dynamics.

Communication Ability to thoroughly present and communicate knowledge gained.

For further details of course goals and professional attribute standards, see the online version of this outline at http:// cusp.eng.usyd.edu.au/ students/ view- unit- page/ alpha/ AMME2500 .

5. STUDY COMMITMENTTutorial: Attendance at tutorials is COMPULSORY and will be counted in the Assignment marks in part or whole

There will be a hand- in assignment associated with each tutorial. Failure to attend one week tutorial (2 hours) will lead to 20% loss of the marks in this corresponding assignment. Failure to attend 6 week tutorials will lead to zero mark in your whole assignment component) Please stay with your timetabled tutorial session in order to record your attendance.

Laboratory: Two 3hr lab sessions per student during the semester. Sessions will commence from the 2nd week of the semester. Experimental time and groups will announced in the first week.

Standard unit of study workload at this university should be from 1.5 to 2 hours per credit point which means 9-12 hours for a normal 6 credit point unit of study. For units that are based on research or practical experience, hours may vary. For lecture and tutorial timetable, see University timetable site at: web.timetable.usyd.edu.au/ calendar.jsp

9. POLICIESAcademic Honesty in Coursework. All students must submit a cover sheet for all assessment work that declares that the work is original and not plagiarised from the work of others.

Coursework assessment and examination policy. The faculty policy is to use standards based assessment for units where grades are returned and criteria based assessment for Pass/ Fail only units. Norm referenced assessment will only be used in exceptional circumstances and its use will need to be justified to the Undergraduate Studies Committee. Special consideration for illness or misadventure may be considered when an assessment component is severely affected. This policy gives the details of the information that is required to be submitted along with the appropriate procedures and forms.

Special Arrangements for Examination and Assessment. In exceptional circumstances alternate arrangements for exams or assessment can be made. However concessions for outside work arrangements, holidays and travel, sporting and entertainment events will not normally be given.

Student Appeals against Academic Decisions. Students have the right to appeal any academic decision made by a school or the faculty. The appeal must follow the appropriate procedure so that a fair hearing is obtained.

Relevant forms are available on the Faculty policies website at eng.usyd.edu.au/ policies. For full details of applicable university policies and procedures, see the Policies Online site at usyd.edu.au/ policy.
