Stretcher bond
This is a restructured version of stretcher bond to make the tower look taller and ventilated. This structure bond can be seen in the midsection of the tower
This week’s task is to build a tower using MDF blocks. The tower must have an opening wide enough for a dinousaur toy to goes in and tall enough for it to accomodate. This tower t uses stretcher bond as foundation and throughout the structure. The use of stretcher bond is because it is stronger and more stable than stack bond. We’ve experimented a new bond in this tower, which lessesn the strength of the tower t considerably. ALso noticed that building stretcher bond takes a large amount of time..

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