Project 2 Crane Model Design brief To design

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

Project 2: Crane Model Material provided: bamboo sticks - @~10 g (200 mm long), a wooden base

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

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

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

Project 2: Crane Model Testing methods: 1) Measure the weight of the crane model with the wooden base by the electronic balance.

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.

Project 2: Crane Model Testing Methods: 4) Count the weights used. 5) Calculate the loading ratio. Higher loading ratio is recorded, higher mark will be given.

Project 2: Crane Model Information: Search for information about frame and structure on internet.

Project 2: Ccrane Model Design consideration: Weight of the crane model Stability Special features of bamboo stick Information Solution Structure

Project 2: Crane Model Suggested Procedures Design Considerations Solution Initial Ideas Make a crane model Testing Evaluation Final Idea

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

Project 2: Crane Model Assessment: Loading Ratio Marks Cannot hold any weight 0 Can hold the hook only 1 <10 2 10 but <15 3 15 but <20 4 20 but <25 5 25 but <30 6 30 but <35 7 35 but <40 8 40 but <45 9 45 10
