Course Aims:
This course will provide students with sufficient knowledge in mechanics of
solids so that they can proceed to the intermediate and more advanced course in
the BEng Materials Engineering programme. Stress-strain analysis of materials in
the linear elastic regime of simple engineering structures under axial, torsional,
shear and bending loads will be introduced.

Grading of Student Achievement: Refer to Grading of Courses in the Academic
Regulations (Attachment) and to the Explanatory Notes.
The grading is assigned based on students’ performance in assessment tasks/activities.
Grade A
The student completes all assessment tasks/activities and the work demonstrates
excellent understanding of the scientific principles and the working mechanisms.
He/she can thoroughly identify and explain how the principles are applied to
science and technology for solving physics and engineering problems. The
student’s work shows strong evidence of original thinking, supported by a variety
of properly documented information sources other than taught materials. He/she
is able to communicate ideas effectively and persuasively via written texts and/or
oral presentation.
Grade B
The student completes all assessment tasks/activities and can describe and
explain the scientific principles. He/she provides a detailed evaluation of how the
principles are applied to science and technology for solving physics and
engineering problems. He/she demonstrates an ability to integrate taught
concepts, analytical techniques and applications via clear oral and/or written
communication.
Grade C
The student completes all assessment tasks/activities and can describe and
explain some scientific principles. He/she provides simple but accurate
evaluations of how the principles are applied to science and technology for
solving physics and engineering problems. He/she can communicate ideas clearly
in written texts and/or in oral presentations.

Grade D
The student completes all assessment tasks/activities but can only briefly
describe some scientific principles. Only some of the analysis is appropriate to
show how the principles are applied to science and technology for solving
physics and engineering problems. He/she can communicate simple ideas in
writing and/or orally.
Grade F
The student fails to complete all assessment tasks/activities and/or cannot
accurately describe and explain the scientific principles. He/she fails to identify
and explain how the principles are applied to science and technology for solving
physics and engineering problems objectively or systematically. He/she is weak
in communicating ideas and/or the student’s work shows evidence of plagiarism.
