TOTAL STUDENT WORKLOAD
Students are required to attend and participate in all the formal timetabled sessions for
the unit. Students are also expected to manage their directed learning and independent
study in support of the unit.
REQUISITES AND CO
This unit further develops the concepts and principles of engineering mechanics
introduced in the Level 4 unit Mechanics and applies
these to the analysis of a range of
complex marine engineering
based problems. The unit allows the student to achieve all
the underpinning knowledge that is required to meet the MCA Applied Mechanics syllabus
at STCW III/2
& Chief Engineer level.
Major themes within the unit will be the effects of bending and torsional forces on
engineering components, the effects and uses of dynamic loading and forces on systems
and the losses and forces caused with flowing fluids.
ful completion of the unit, students should be able to:
Knowledge and Understanding
Define, explain and justify key principles and concepts in mechanical engineering
and how they are applied in the marine environment.
opriate formulae and methodology to investigate and solve complex
problems of engineering mechanics as applied to the marine engineering field.
Apply developed understanding of engineering mechanics principles and concepts
to analyse the performance a
nd effectiveness of aspects of mechanical engineering
Transferable and Key Skills
Interpret and communicate ideas and essential data effectively.
Implement an analytical and diagnostic approach to problem solving.

LEARNING AND TEACHING STRATEGY
d unit will be delivered as a series of lectures interspersed with
limited tutorial sessions. Students will be expected to read up on topics in advance to
prepare themselves for the lectures. During the tutorial sessions students, with lecturer
and assistance, will work on tutorial worksheets covering the relevant topic.
These worksheets will provide mathematical questions to allow students to put the lecture
material into practice and students will be expected to finish the worksheets during
dependent study time, seeking additional guidance as required. The worksheets will be
available on the unit myCourse page and worked answers will be made available after a
suitable time period. Students will be responsible for their own learning and main
their progress through the worksheets.
In order to assist learning, the tutorial worksheets are designed to enable students to
recognise their individual understanding and level of ability in a formative manner; this
will be a
chieved through access to solutions to tutorial sheets via myCourse. The end of
unit examination will be a summative assessment of all the learning outcomes.
Closed book written examination.
Referral will consist of a resit paper.
