2. Overview
• Experimental Objective
• Introduction
• Background Information
• Materials
• Procedure
• Data/Observation
• Results
• Conclusion

3. Experimental Objective
• Design and construct boom
• Enter boom in competition against other booms
• Learn how booms are used and factors
considers while designing
• Create a boom that extends 1.5 meters from the
edge of the anchor

4. Introduction
• Booms lift and move heavy loads
– Loads even heavier than the actual boom
• Some examples of booms
– Cantilever Boom
– Rotating Boom
– Telescoping Forklift Boom
– Architecture Boom

Bridge (double cantilever)

5. Background Information
• When constructing a boom engineers must be
aware of stress and strain
• Stress is the external force acting upon an object
• Strain is the measure of deformation cause by
stress

6. Background Information
• There are three types of stresses:

7. Materials
• 2 Thick Dowels (7/16 in. x 48 in.)
• 2 Thin Dowels (5/16 in. x 48 in.)
• 6 Bamboo Skewers (12 in.)
• Cellophane Tape
• Kevlar String

8. Procedure
• Sketch design of boom
• Collect materials
• Carved 2 wholes into 1 thick dowel
• Cut 2 thin dowels in half
• Tape the 2 thin dowels together
• Connect Kevlar string to the thick dowel
• Ask TA weigh boom
• Calculate boom weight and design ratio

9. Procedure

12. Results
• Our boom was tied in 5th
place.
– Weight of boom: 273.000g
– Anchor time 120 sec.
– Length 1.45 m

13. Conclusion
• Boom came in 5th place
• Future improvements include:
- Build a stronger boom
- Test trial the design before entering it into
the competition
- Plan out time
