MECH104P - Engineering Dynamics
Code: MECH104P
Alt Codes: None
Title: Engineering Dynamics
Level: 1
UCL Credits/ECTS: 0.5/7.5
Start: January
End: April
Taught by: Dr PJ Tan
Prerequisites:
ENGS103P Mathematical Modelling and Analysis and MECH101P Introduction to
Mechanical Engineering. A-level physics and Maths will not be a substitute.
Course Aims:
The aims of the course are two-fold. First, it aims to teach the basic analytical
methods, that is, the fundamental concepts and techniques of engineering dynamics.
Second, it aims to show the implementation of these methods in the design and
analysis of simple basic mechanisms.
Method of Instruction:
Lectures and tutorials. Tutorial sheets and other exercises will be used to provide
formative assessment. Practical classes related to the reinforcement of conceptual
ideas taught in this subject will be conducted and assessed in MECH102P
Mechanical Engineering Practical Skills I.
Assessment:
Written examination (100%)
To pass this course, students must:
Obtain an overall pass mark of 40%
Content:
The course concentrates on dynamics where the concepts of Newton’s Law of
motion, forces, work, energy, momentum and impulse will be covered and explained
in depth using examples from everyday phenomenon such as ‘Why do hurricane in
the northern hemisphere rotate counter-clockwise?’, ‘What is the energy loss from
two colliding snooker balls?”, “Where should a door-stopper be placed to prevent the
door hinges from coming loose?”, etc.
