6. Problem Statement
Our group is working for Middle Ages military manufacturer in Europe. Have been asked to design catapult that will throw tennis balls further than any other. For King’s safety, catapult will be operated from distance of at least four feet.

7. Background Occurring in Middle Ages (1450 A.D.) In Europe
Military manufacturer
Assigned by King
Needs to throw tennis ball at least 30 ft.
Operate from at least four ft.

8. Customers
Mr. Pritchard
King

9. Scope Design, build and test a catapult Deliverables: Final report
Power Point
Catapult
Resources: Mr. Pritchard, Internet, and Parents of members

10. (Cont.) - Materials: Wood Screws Bungee cord Screw with hook
Tennis ball
Metal and Wood Rod

11. Deliverables
Technical Report
Power Point
Catapult

12. Brainstorming - Catapult’s function - Catapult types - Wood types
- Base types

13. Research and Generate Ideas
Function
- Used during attacks
- Flung giant boulders at enemies
Types
- Trebuchet (deals with balance)
- Onager (uses wire/tension to fire arm)

14. (Cont.) Wood Types Base Types - Whitewood, oak, pine, birch and maple
- Hollow square base
- Full base
- A triangle base

15. Criteria and Constraints
- Throw from 4 ft.
- Throw at least 30 ft.
- Can’t be taller than 24”
- Base can’t be more than 24 x 24”
- User safety

16. Nicole’s Solution Pros+ Cons- + Trajectory angle drawn + Dimensioned
+ Parts describe what they do
+ Scale drawn
- Hard to follow
- Hard to build
