Material: In this week task the material for building a tower is medium density fibreboard blocks. MDF is made from =mber fibres glued under heat and pressure. They are dense, light, s=ff, and flat. Shape and weight of blocks we used in week one are the same, they all shaped in cuboid blocks with flat surface and light weighted. Brief: Build a tower using provide material(MDF blocks) and only use this material to build a tower, which an entry. The space inside should big enough for one elephant toy could get in and turn around. The tower should built as tall as possible. Force: Defini=on: According to Ching(2008), A FORCE is any influence that produces a change in the shape or movement of a body. Forces are represents by arrows, the length of arrows is propor=onal to the magnitude and the direc=on is showed by the posi=on of arrow. Tension: Tension forces are stretch and elongate the material. Compression: Compression forces result in the shortening of the material.
Building Tower-‐Week 1
The base was build in circular shape, compare with the other groups work which are square shaped base, the round base are stable and easier to build, because for the square shaped base when built the edge and corner the blocks are in different direc=ons, the surface which touched both blocks are smaller than a round one.
In this stage, the difference of two side is start to appear. We make two to three layer of blocks which are changed direc=ons. By doing this there are more surface area and less gap area, to make it more stable.
It is harder to connect at the corner and edge when it is a square shaped base. And by the load path shows in different ways.
Load Path and reac=on of tower
one side of our tower is curved and one side of tower is much more straight than another side, aVer we achieve the height of the elephant we start to built it in smaller area and on the straight side of the tower, and make a hole on the curved side. Because at that side there are less load force, make it easier to make a hole.
Because of the gaps between two blocks and at next layer, put the block on the gap, the load path is almost a straight line, which means is very stable.
Building Tower-‐ Week 2 Material: The material we used in this week is Balsa wood, Balsa is a fast growing tropical tree, the =mber slice of Balsa wood is strong and yet very light weighted, Balsa wood is easy to cut when cuXng along the grains. Brief: Build a tower using Balsa wood and glue, build as tall as possible.
The stand of this tower is based on a triangle shape, by this, triangle is as stable as a rectangle one and save the limited materials.
Because of the different size of two strips, and there has no supports at this point it was not stable, to resolve this problem, put a liZle =mber strip around this point and keep it straight.
