Group: 1 Class: Introduction to Engineering (Mr.Cornish) Period: 9 Date: May 20, 2013

The  project  objective  was  to  learn  about  basic  projectile  motion  theory,  the  mathematical models  applicable  to  various  projectile  motion  situations  (e.g.  catapult launch), and construction techniques  for  specific  raw  building  materials.  In  addition,  a   catapult  was  to  be  implemented and  built  based on  an  existing  design;  this  design  was  to  be documented  prior  to  building,  and used   as  the  primary  documentary  source  when  constructing  the   contraption.  Furthermore, an eggonaut  was  to  be  designed  and  then  built  for  the  sole  purpose  of  protecting  a  raw  chicken egg  from  breaking  when  launched  from  the  catapult.  Lastly,  component  designs  and scientific/engineering principles at work were to be demonstrated by the model.

The following were the specifications, goals/requirements, and constraints for the catapult:

● ● ● ●

A document on an existing catapult design (including sketches, dimensions, materials, Bill of Materials, and estimated build procedure) was to be created prior to construction This documentation was to then be used to replicate the existing design (original) using all the same parts and materials, within the documented specifications Individual documents were to be produced outlining the work undertaken Contraption was to be fabricated within the provided specifications:

the physical device must:

■ ■ ■ ■ ■ ■ ●

be complete and safe load a raw chicken eggonaut capsule easily work; must protect the egg from breaking upon dropping be fabricated at school be left at school be fabricated from supplied materials [similar to those in original design]

A strict timeline was to be adhered to (each day)

After  the   project  objective,  goals,  and  constraints  ...
