These two graphs is about our first plan in tutorial 2. Triangle is the stable shape. Hence, we try to use the triangle as the foundation for our building. In the three corners we use the small boards to support which form three small stable triangles (like figure 2). There have another problem for this foundation. The connection of the board is easy to sag. This problem made us to take long time to create this foundation.
Small triangles to make connection more stranger.
Figure 3 figure 4 We try to build up the tower. However, the connection is very easy to break. Hence, our group changed the foundation to rectangle. We still keep the small triangles in the connections to make the tower stranger. In the tutorial 2 we took long time in connect the boards because of glue is difficult to dry. In the top our tower, we borrowed other group's gummed paper to get them together. After we finished tower, we take the pressure test. Unfortunately, our tower is very easy to broken. The sides of the triangle are easy to break. We need to make stranger of the sides. There have another reason for this problem is we cut the board in different size. The board to week to support heavy things.
We try to use the fixed joint in our tower. The connection of the tower took our times and the glue is difficult to connect the board. There have another mistake we should avoid in the process of creating tower. It is the cutting boards. We should make sure the boards were cut in the regular shape for the connection.
Figure 5 The sides of the boards need cut like figure 5. It is easy for glue on the surface. However, in our group we cut boards without smooth surface. This was a season for our tower which is easy to break.
