Making Structural Bridge
Experiment 1
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.
Resulting Video:
The outcome is a failure because the design is not long enough for the sides of the design to sit properly on the tables.
Experiment 2
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 only 1 bag of paper
Structure wih 2 bag of paper
Structure collapse
Resulting Video:
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.
Experiment 3
Materials:
Materials:
- Paper
- Tray
Final Design:
The paper design we made is wrapped up by more than 20 papers. It is design as shown above because we believe that by adding a few springs inside the rolled paper, it will give the papers a more firm 'bridge'.
Testing Process:
Structure with 4 bag of paper
Due to the structure not collapsing, a force
is given in order for it to collapse
Resulting Video:
At the end, the design succeed the expoeriment.
