Course Objectives:
To develop design skills according to a Conceive-‐Design-‐ Implement-‐ Operate (CDIO) compliant methodology.
To apply engineering sciences through learning-‐by-‐ doing project work.
To provide a framework to encourage creativity and innovation.
To develop team work and communication skills through group-‐based activity.
To foster self-‐ directing learning and critical evaluation.<br>

Copyright 2013-‐2014 About the Project 14/01/16 14:40 Alpana Agarwal, ECED 3 The Project will facilitate the design, construction and analysis of a “Mangonel”. In addition to some
introductory lectures, the content of the students’ work during the semester will consist of:
the manufacturing and assembly of a Mangonel from a Bill Of Materials (BOM), detailed engineering drawings of parts, assembly instructions, and few prefabricated parts;
the development of a software tool to allow the trajectory of a “missile” to be studied as a function of various operating parameters;<br>
04
Copyright 2013-‐2014 About the Project 14/01/16 14:40 Alpana Agarwal, ECED 4 a structural analysis of certain key components of the Mangonel for static and dynamic stresses using values of
material properties which will be experimentally determined;
the development of a micro-‐electronic system to allow the angular velocity of the throwing arm to be determined;
testing the Mangonel;
redesigning the throwing arm of the Mangonel to optimise for distance without compromising its structural integrity;
an inter-‐group competition at the end of the semester.<br>
05
Copyright 2013-‐2014 Course Learning Outcomes (CLOs) 14/01/16 14:40 Alpana Agarwal, ECED 5 Upon completion of this module, students will be able to:
model trajectories of masses with and without aerodynamic drag;
develop a software tool to allow trajectories be optimised;
analyse the static and dynamic stresses of elements of an engineering mechanism;
optimally design structural elements of an engineering mechanism;
perform a test to acquire an engineering material property;
develop and test software code to process sensor data;<br>
06
Copyright 2013-‐2014 Course Learning Outcomes (CLOs) 14/01/16 14:40 Alpana Agarwal, ECED 6 design and construct and test an electronic hardware solution to process sensor data;
construct a Roman catapult “Mangonel” using tools, materials and assembly instructions;
operate and evaluate the “Mangonel” for functional and structural performance;
validate theoretical models by comparison with experiments;
integrate skills to innovatively redesign an element of the “Mangonel”;
participate and cooperate in a team.<br>

Copyright 2013-‐2014 What is Catapult/Mangonel? 14/01/16 14:40 Alpana Agarwal, ECED 7 Used in the medieval period to throw projectiles at a castle's walls
Types – Siege, Mangonel and Trebuchet
The mangonel threw projectiles on a lower trajectory and at a higher velocity than the trebuchet, with the intention of destroying walls, rather than hurling projectiles over them. It was more suited to field battles.<br>
08
Copyright 2013-‐2014 What is Mangonel? 14/01/16 14:40 Alpana Agarwal, ECED 8 Mangonel is derived from the Greek
mágganon, meaning "engine of war”
But mangonel may also be indirectly referring to the mangon, a French hard stone found in the south of France.
The Arabic term manajaniq comes from the same word, and applies to various kinds of trebuchet.<br>
