The Mass Tower We are required to make a tower that made my wood blocks. The Tower should be including the window and the door which means we have to keep the space during the time when we built it! Foundation Our group decided to make the shape as a circle because circle is very stable and we keep the side open for the door as image shows.
Process:
We uses structural as show on the sketching that the frame is able to support the weight on each block. Additional, in order to close top of the tower we move each a little bit close to the central of the circle which shows on the sketch. We perspective that the total feature of the tower will looks like a cone!
Problems: When we built the tower to the fifth floor we realize that the building is not as stable as we wish because if every blocks is directed to the central of the building and they will trend into the middle and falls down before we close the top.
Solution: We decrease the radius of the circle even the tower may become lower than before.
Challenge: We leave a hue space for the ‘door’ that makes us struggling to connect each side together.
Solution: One man added one block on each side and the other man have to support the tower otherwise it will falls down.
Finishing: After we connect the both side together there is nothing struggling for the process until we saw the project built by other group which is taller than us. As the image shows we add two blocks each and cross together which is able to increase the height of the tower but less weight occur.
Testing: After all we tried to make a window at the other side of the tower. Initially, we tired to move one block in the middle out and find that there is not any effect for the stablish. We move the block one by one until the ‘window’ touch the ground. It looks like the building support by the three fulcrum and it is able to make the project stable.

Balsa Tower Main Material: Balsa Wood Task : Cut the Balsa Wood into 20-40 pice by the cutting knife then connecting those balsa wood to build up a frame in order to make a tower as high as possible. Preparation: In order to cut those Balsa in the same size and as much as possible, i mark both side of the wood and the width is 2.5mm each.
Hardship: I dont have any equipment to hold the wood and the rule the is not long enough so that it is hard to cut them in the same size. Some of them is not able to make the frame which can br seen from the image. Finally, there are 29 pieces of Bolsa wood are able to make the project.
Starting: We plan to make four rectangle grame at first and there is a piece of wood across it which able absorb more compression force from the frame.
We tried to uses Pva to stick each pieces of Balsa together, however, we find that it is not strong enough so we decide to use te tape to cover the connection point which can make it stronger.
Improving: By follow the suggestion from the tutor, we added another piece of wood cross the frame.
Processingďźš We realize to make that trangle base is stable and abl to save a lot of time so we change our planning. We put three frame together but the three connection are not in the same level so we cut some extra Bolsa.
The basement is really stable so we decide to put another triangle on the basement and it looks so far so good.
BY the success we have, we put a convert triangle frame on it and the game which is anti Physical Law Makes us almost give up.
The only chance to increasing the height of the project si put single piece of he wood. Moreover, we have to use another piece of wood to hold the one which almost broken. Even we put one on the basement in order to make it keep standing on the ground Testing: We slowly break every pieces of Balsa we can destroy expect the three main pieces of wood and the one connect in the middle..
