    Assessment and Feedback Specification Unit: Fundamentals of Mechanical Vibration (MCEN2005) Title: Assignment 2 Activity: This assignment develops the skill of applying a numerical solution technique to a high degree-of-

    freedom lumped-parameter vibration system. The activity will lead you to: Be able to use Holzers method to solve for natural frequencies and mode shapes. Recognise that a real marine drive system can be quite complex. Understand how to describe a mode shape. Determine the engine speed that would excite natural torsional vibration modes. Check tour solution by another method.

    For a detailed Assessment description and specification of work to be done see the briefing sheet on Blackboard. Assessment criteria, marking distribution and Engineers Australia competencies addressed Value of the assessment based on the rubric provided below: 10% of unit grade. The total assessment mark awarded consists of the sum of the marks awarded to each assessed element. Each item of the assessment rubric shows the ENGINEERS AUSTRALIA Stage 1 competencies to be demonstrated. Level of learning (Levels of learning) is specified for those elements of the assignment when it is appropriate.

    Detailed guidelines and feedback This detailed assessment rubric sets out assessment expectations so that you will be aware of the competencies to be developed and the standards expected. This table will also be used for assessing your work to provide feedback on your performance against these standards. This sheet is NOT the assignment cover sheet.
