Vertical Stability - Week 3
CARD TOWER
Material
When the tower was blown gently, the tower only swayed a little. But as soon as a huge blow was given, the tower collapse.
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.
Horizontal Span - Week 2
Exercise 2: Horizontal Span
SATE STICKS
Material
The outcome is successful as it can withstand a few bag of papers as well as 2 people.
SATE STICKS AND RUBBER BAND
Material
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
The outcome is quite a success. The form of the paper was deformed due to great amount of compression load applied.
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.
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.

Horizontal Support - Week 1
Exercise 1: Horizontal Support
Materials:
SATE STICK AND RUBBER BAND ANCHOR BRIDGE
Materials:
At the end, the design succeed the experiment.
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.
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.
