Vertical Stability - Week 3

CARD TOWER

Material 
  • Deck of cards
  • Paper Clip
Final Design

In order to build up the highest tower which can withstand the blow test, we decided to design a tower using playing cards and paper clips. The design chosen by the group is a triangulated tower with a base that surrounds the main tower to give it some structural support so that when blown, it won't easily collapse.



The triangulated base supports as a base to secure the cards onto the ground firmly. The cards are then joined together in a triangular shape by paper clips. The reason why a triangular shape is chosen is so that more cards can be used to stack up making the tower taller.

When the tower was blown gently, the tower only swayed a little. But as soon as a huge blow was given, the tower collapse.

Horizontal Span - Week 2

Exercise 2: Horizontal Span

SATE STICKS
Material
  • Skewers
  • Hot glue gun
Final Design:



We decide to make a design as shown above so that the 'bridge' can hold a huge amount of load when applied. beside that, it is also quite appealing aesthetic wise.


The outcome is successful as it can withstand a few bag of papers as well as 2 people.

 SATE STICKS AND RUBBER BAND

Material
  • Skewers
  • Rubber band
Final Design:



The design chosen for 2nd experiment is as shown above because that with the bridge can stay balance even if there is a heavy load applied.



The outcome of the experiment is a failure. Evn though it didn't collapse, but as more load is added, the design started tilting to one side.

 PAPER BRIDGE

Material
  • Paper
Final Design:



The design for the paper bridge is a similar to that the first experiment design except this time, instead of a spring, the inside of the paper is rolled paper stuffed in as many as possible, with the hope that it can withstand the heavy load.





The outcome is quite a success. The form of the paper was deformed due to great amount of compression load applied.

Horizontal Support - Week 1

Exercise 1: Horizontal Support
SATE STICK BRIDGE

Materials:

  • Skewers
  • Hot glue gun
  • Tray
Final Design:


The design we decide on is this 'span bridge'. The reason being for the force of the load to act on the centre and give a balance so that the 'bridge' won't collapse. 


Structure with 4 bag of paper


The outcome is a failure because the design is not long enough for the sides of the design to sit properly on the tables.

SATE STICK AND RUBBER BAND ANCHOR BRIDGE

Materials:
  • Skewers
  • Elastic Band
  • Tray
Final Design:


This design is used because we believe that this type of 'truss bridge' would hold up the load firmly.

Testing Process


Structure with 2 bag of paper


Structure with 2 bag of paper


Structure collapse

 
In reality, the design could not withstand the load because the rubber joints did not join the skewers firmly, causing the bridge to collapse to one side.

PAPER BRIDGE

Materials:

  • Paper
  • Tray
Final Design:


The paper design we made is wrapped up by more than 20 paper. it is design as shown above because we believe that by adding a few inside rolled paper, it will give the papers a more firm 'bridge'.


Structure with 3 bag of paper


Structure with 4 bag of paper


Due to the structure not collapsing, a force is given in order for it to collapse



At the end, the design succeed the experiment.
