This week’s task is to build a towerusing MDF blocks.The tower must have an openingwide enough for a dinousaur toyto goes in and tall enough for it toaccomodate. This tThis tower uses stretcher bond as foundation and throughout the structure. The use of stretcherbond is because it is stronger and more stable than stack bond. We’ve experimented a new bond inthis tower, which lessesn the strengthof the tof the tower considerably. ALso noticed that building stretcher bond takes a large amount of time..

This is a restructured version of stretcher bondto make the tower look taller and ventilated. This structure bond can be seen in the midsectionof the tower

Stretcher bond

acts like pillars

Tension Compression

- pulls, moves apart and undergo tension- stretches and elongatethe material- elongation depends on: 1) Stiffness 2) C 2) Cross sectional area 3) Magnitude

- pushes, moves closer (compact)

- shorten the material

This week’s studio session requires each group to cut out 40 strips of balsa and build a skeletal

structure out of the strips. We are allowed to use superglue and a small amount of masking tape on

our structures. The aim is to build a structure that could reach the ceiling, but nobody in my studio

built a structure that reaches the ceiling.

I learnt that using more glue than neccessary will result in the delay of building because the glue will

take a while to dry. It is very important for time limited tasks because we could not use all the balsa

strips due to the fact that strips due to the fact that we ran out of time.

Using masking tape on the balsa strip to keep them straight does not help because they became very

thick and bulky and the structure will start to deteriorate.
