COURSE DETAILS

Units of credit

This is a 6 unit-of-credit (UoC) course, and involves 6 hours per week (h/w) of face-to-face

contact.

UNSW expects that you will put in, on average, about 46 h/w for 24 UoC (including both in-

class and out-of-class time) for an effective 14 weeks of the semester (12 weeks plus stuvac

plus one effective exam week) for an average student aiming for a credit grade. Various

factors, such as your own ability, your target grade, etc., will influence the time needed in

your case. Some students spend much more than 46 h/w, but you should aim for not less than

46 h/w on coursework for 24 UoC.

This means that, for this course, you should aim to spend not less than an additional six hours

per week of your own time. This should be spent in making sure that you understand the

lecture material, completing the set tutorial problems and further reading about the course

material.

Parallel teaching

There is no parallel teaching in this course.

COURSE AIMS

Course aims

The course aims include developing and further your skill in solving technical problems and

familiarizing you with analysis: of membrane stresses in axisymmetric thin shells, stresses in

long thin beams, buckling of columns, torsion of thin tubes, deflection analysis, statically

indeterminate beams. You also will learn elementary concepts in the area of mechanics of

fracture and fatigue. Knowledge of these topics is vital in design, analysis and integrity

assessment of mechanical systems.

How the course relates to other course offerings and overall program(s) in the discipline

This is a third year course in the area of mechanics of solids. Having learnt the basis of statics

in MMAN1300 and elementary topics in area of the mechanics of solids including basic

stress/strain analyses in MMAN2400, this course applies the knowledge obtained in the

previous static and mechanics of solids courses to analysis of thin shells, beams and columns

as well as introduces the students to some advanced topics in mechanics of solids such as

mechanics of fracture and fatigue.

RATIONALE BEHIND THE APPROACH TO LEARNING, TEACHING AND

TEACHING STRATEGIES

The teaching strategies that will be used and their rationale

The teaching strategies that will be used include:

Presentation of the material in weekly lectures so that the students develop

understanding of the underlying concepts of the various topics covered in the course.

Provision of weekly supervised tutorials where students can obtain assistance and

develop their skill in solving technical problems.

Provision of laboratory classes where students work in teams to perform physical

experiments, analyse data and produce pertinent reports about which students will

receive feedbacks.

Suggested approaches to learning in the course

Regular attendance and participation in lectures, tutorials and laboratory classes

Diligence in working through the set tutorial problems in preparation for examinations

Effectively utilising the tutors

Additional reading on, and about the material presented in lectures to broaden the

students understanding

Practicing past examination questions in preparation for examinations

Working effectively with other students in carrying out the laboratory experiments.

Further comments on teaching

Teaching ranks amongst the nation‟s top prestigious professions where one is involved in

shaping the future of the country. Understanding how students learn is one of the significant

aspects of teaching. This is linked to their knowledge, background and maturity. The key is to

relate to the students by starting from what they know in elementary courses in the area of

solid mechanics and building upon it. The topics covered in this course are applied fields

where students constantly apply the fundamental concepts and theory learned in the classroom

to analysis of various components. My main goal is to encourage independent thinking and

analytical reasoning to augment students‟ problem solving skills. During the lectures, I

prompt students to question at every stage: ‟why‟, ‟how‟ the problem at hand should be

tackled. My favourite approach is: “If you don‟t have any question I have some for you”. This

may lead to classroom discussions and/or several intellectually stimulating

questions/arguments which are not easy to answer.

While this course uses a textbook, I believe that there should be enough room for flexibility

and I tend to adapt to the students‟ requirements as the course proceeds. Therefore, additional

materials to those described in the textbook may be covered in the lectures or alternatively not

all materials described in the textbook may be referred to in the lectures.

The format employed in this course combines face-to-face lectures, interactive tutorial

sessions as well as laboratory classes. The students work within a team during the two

physical laboratory experiments but each individual has to provide an independent report. In

addition, each student has to take individual initiative to carry out the finite element

laboratory and analysis the „shear-centre‟ of a beam before the pertinent material is covered in

the lecture.

ASSESSMENT

Overall rationale for assessment components and their relationship with specific student

learning outcomes

This course will be assessed by in-semester quizzes and tests, laboratory reports and a final

formal examination. The topics covered in all assessments are directly related to the expected

outcomes listed before. All assessments are CLOSED BOOK.

Details of each assessment component, the marks assigned to it, and the dates of

submission

Assessment

Mark 2 Laboratory classes 10%

Quizzes 1, 2, 3 and 4 through semester 20%

End-of-Block 1 Exam 35%

Final Formal Exam at the end of semester 35%

Total 100% In order to pass the course, you must achieve a total mark of 50% or higher. Supplementary

examinations will not normally be granted unless you have a valid special consideration.

You will need to provide your own calculator, of a make and model approved by UNSW,

for the examination. The list of approved calculators is shown at:

https://my.unsw.edu.au/student/academiclife/assessment/examinations/Calculator.html It is

your responsibility to ensure that your calculator is of an approved make and model, and to

obtain an “Approved” sticker for it from the School Office or the Engineering Student Centre

prior to the examination. Calculators not bearing an “Approved” sticker will not be allowed

into the examination room.

Four Quizzes will be held in the tutorial classes on Wednesdays during tutorial time periods.

Approximately, Quiz 1 will be held on Wednesday 14th

March (Week 3) from 6-7 pm, Quiz

2 will be held on Wednesday 28 March (Week 5) from 6-7 pm, Quiz 3 will be held on

Wednesday 02nd

May (Week 9) from 6-7 pm and Quiz 4 will be held on Wednesday 16th

May (Week 11) from 6-7 pm. The students‟ grouping for quizzes will be announced during

lectures in due course. The above-mentioned dates might be changed depending on progress

in lectures. If so, the new dates, time and venues for the quizzes will be announced during the

lectures.

End-of-Block 1 Exam covering all topics in Block 1 will approximately be held in Centre

Lecture Block 8 from 4 – 6 pm on Monday 16th

April (Week 7). This date might be changed

depending on progress in lectures. If so, the new date, time and venues for this exam will be

announced during the lectures.

Laboratory experiments and reports: A standard specification is available from the School

office to aid presentation of your laboratory reports (in all courses). All submissions should

have a standard School cover sheet. All submissions are expected to be neatly typed and

clearly set out. All calculations (may be hand-written) should be shown as, in the event of

incorrect answers, marks are mainly awarded for method and understanding.

The preferred set-out of any numerical calculation is similar to the following:

= (Equation in symbols)

= 1.025 200 (Numbers substituted)

= 205 t (Answer with units)

Late submission

You need to submit your two laboratory reports no later than 10 am Thursday 26 April

(Week 9) to the Solid Mechanics Laboratory (L101). Due to large number of students and

heavy marking load, no late report will be accepted.

Marking Criteria

Quizzes and Exams: In marking the quizzes and exams the major portion of the marks will

be allocated to correct drawing of any pertinent free-body diagrams and correct method of

solution.

Laboratory Reports: In marking the laboratory reports, particular attention will be paid to

correct and neat presentation of the data, calculations and comprehensive discussion and

conclusions.
