1. Project 2: Crane Model
Design brief: To design and make a bamboo crane model for learning purpose
Group : 4 members
Duration: 3 cycles

2. Project 2: Crane Model
Material provided: bamboo sticks (200 mm long), a wooden base

3. Project 2: Crane Model Requirement :
1) The bamboo crane model should not be shorter than 250mm long.
Bench
>250mm

4. Project 2: Crane Model Requirement :
2) The model should be gripped firmly on the bench and weights are placed one by one at the end of the crane model until it breaks down so as to test the loading ratio.
Bench

5. Project 2: Crane Model Requirement :
Maximum Loading
Weight of the Crane Model
Loading Ratio =
3) The model must be built with the bamboo sticks provided by the teacher and be fastened with hot melt glue.

6. Project 2: Crane Model Testing methods:
Measure the weight of the crane model with the wooden base by the electronic balance.

7. Project 2: Crane Model Testing Methods:
2) Grip the crane model on the bench by a bench hold fast.
3) Hang the hook at the end of the crane model and place weights one by one on the hook base until the model breaks down.

8. Project 2: Crane Model Testing Methods: Count the weights used.
5) Calculate the loading ratio. Higher loading ratio is recorded, higher mark will be given.

13. Project 2: Crane Model Safety:
Must take care in using the hot melt gun in order to avoid to be burnt.
b) Never touch the melted glue directly.
