Outline of compression and tension as well as a photo series of the tutorial building activity.

Week 1 Tutorial Activity Topic: Compression and Tension Both compression and tension are structural features associated with physics. Compression Tension Description When compression occurs, gravitational
forces are pushing against the object. When tension occurs gravitational forces are pulling away from the object. This is usually carried out through a string, cable or chain.

Link between Content and Building Blocks Activity The building blocks activity in the first tutorial provided a practical example of compression and how the forces of compression can be tested by large structures. The task involved building a tall structure with building blocks and testing how many blocks could then be removed before the structure fell. Photo series of our structure and Load paths (à)
Description and Analysis of the Construction System
Blocks were not placed too close together, a space was allowed to aid in the stability of the building. Where blocks had been placed too close together, the structure weakened and these were the regions that gave way when the structure collapsed.
Efficiency of Material The building blocks material was appropriate for the task undertaken. The size of the blocks allowed for a stable yet tall structure and had enough grip and friction for the forces of compression to occur. The blocks were also lightweight.
1st stage Started building the structure by leaving a whole for the figurine – however this resulted in the challenge of closing the roof
2nd stage A secondary arch was built as well as a bridge
3rd stage We began building an offshoot structure and removed the blocks to make an arch
4th stage Created a pathway and steps for the bridge
5th stage The structure was finished and we stacked the last few blocks at the top
6th stage After removing between 20 and 30 blocks the structure collapsed towards the weaker side
