Mechanics 2: General information
Module aim
❑
The aim of the module is to enhance students'
knowledge and understanding of the mathematics
and scientific principles related to mechanics and
materials, and to develop their ability to apply this
knowledge in a number of topics.
Mechanics 2: General information
Learning outcomes
Subject-specific Knowledge:
❑ At the end of the module the student
should be able to demonstrate
knowledge and understanding of the
theory and application (problem solving)
of the engineering mechanics covered
in this course.
Mechanics 2: General information
Lecture material and examples: Pre-recorded and
available on Canvas
Tutorial: Selection of questions are pre-recorded and
available on Canvas. All solutions uploaded on Canvas.
Module breakdown:
❑ 20 hours of lectures: 10 hours on statics and 10
hours on dynamics (pre-recorded lectures broken
down by weeks on Canvas)
❑ 20 hours of tutorials: 10 hours on statics and 10
hours on dynamics (broken down by weeks on
Canvas)
❑ In addition there is independent study
Mechanics 2: General information
Core texts (Resource lists on Canvas):
❑
The recommended text are the same as for
the 1st year Mechanics 1 Module.

Mechanics 2: General information
Modes of teaching and learning:
Pre-recorded Lectures
❑ The Mechanics 2 course is covered in
pre-recorded lectures. The pre-recorded
lecture sessions are all and available on
Canvas.
1.
❑ In
addition, all lecture notes with the
material covered in pre-recorded lecture
are provided on Canvas.
Mechanics 2: General information
Modes of teaching and learning:
2. On campus sessions
❑ There will be a two hour guided study per week on campus to
enable the opportunity for students to engage with the module
material. The expectation is that students will have watched the
pre-recorded weekly content beforehand.
3. Tutorials (2 hours on campus sessions)
❑ The tutorials questions and solutions are available on Canvas
as PDF documents.
❑
There is also a selection of solutions that are pre recorded and
are available on Canvas.
Mechanics 2: General information
Modes of assessment:
❑ Main
assessment:
• Summative Laboratory Report
(Semester 1) (20%)
Please note that the exact dates of the
lab report submission will be
communicated during Semester 1.
Students will submit one report only.
• Summative 3 hour Exam (January
exam/assessment period) (80%).
Students will answer all questions.
Mechanics 2: General information
Modes of assessment:
What happens if you fail the module in the main period?
❑
If a student fails the module, they will be allowed to
re-sit in the Supplementary exam period.
❑ If a student fails the module, and has failed the lab
report component, they will be allowed to re-submit a
lab report in the Supplementary period.
❑ If a student has failed the module but passed the lab
report component, you are not required to submit
another lab report and your mark will be carried
forward into the supplementary period. In this case
you only need to re-sit the exam in the
supplementary exam period.
Mechanics 2: Subject matter
Mechanics: The study of how bodies react to forces
acting on them
Dynamics (study of motion):
Statics: The study of
bodies in equilibrium
1. Kinematics- Concerned with
the geometric aspects of
motion (s,ν,a, and t)
2. Kinetics- Concerned with
the forces causing the motion
