RAG 132- Introduction to Build Environment & Human Settlement: Assignment 2 : Geodesic Dome

Day : Wednesday

Date : 28th July 2010

Venue : DK E48B, HBP

Time : 09:00-11:00 am

Today, Mr. Wan give us a new assignment. Mr. Wan asked we need to build a geodesic dome. In build a geodesic dome, there were 6 element that plays its own part. The element are:-

Intention:

To build of a model of a geodesic dome.

Act :

We start to build of a model of a geodesic dome using bamboo satay sticks.

We build the model in 2v.

Actor :

Normah (Me)

Rule :

Cut the bamboo satay sticks at the same lengths.

Make the dome at the right time to finish the dome.

Place :

In my room.

Product :

A model of a geodesic dome.

Material :

Bamboo satay sticks.

Masking tape

Scissor

Cutter

Ruler

A marker

Step how to make a geodesic dome :-

First of all, we need to decide what type of dome we want to build.

Once we have decided what kind of dome we are going to build, we need to decide on a size. So, we choose to build 2v dome.

Then, we use dome calculator to calculate the radius for dome. There are only two lengths involved for 2v dome build. The number of 2v dome radius is 12cm. The side A which is 7cm and side B is 6cm.

We need to measure the length of bamboo satay sticks and then point it.


Point the length of bamboo satay sticks.

After that, cut the bamboo satay sticks into 6cm and 7 cm.

Cut the harder sticks.

Cut the bamboo satay sticks into 6cm and 7cm

6cm long


7cm long

Next, joining 10 sticks (6 cm long) using a masking tape.


put the sticks end to end.


Then, bend the 6cm sticks with masking tape.

Then, bend the sticks until it shapes a decagon, after all the 10 sticks are joined.

Make a decagon

its base dome

After that, joint 2 sticks together (6 cm with 6 cm long and 7 cm with 7 cm long). Each 6cm and 7cm can make 5 joints.


Joints 2 stick together.

All of sticks are joint alternately 6cm and 7 cm.

Stick joint alternately

Make another decagon with joint the 6cm until 10 sticks. The decagon is then stick on to the edges of the triangles.

A decagon

Then, make a triple sticks joint. Stick it on the middle edges of the triangles with the 6 cm long stick and the left and the right side of triangle with 7cm. At the middle of pentagon should make a star shape.
