Week 2 Activities

Horizontal Support

Structure 1: The Snare

Sate sticks and hot glue

Structure weight: 50g

Structure height: 35mm

Hypothesis: 10 (25kg)

Fail: Twisted / lent to one side.

Method of Construction:

Close up of
hot glue joints

Three sticks were arranged in the shape of a triangle and hot glued at each connection. Another three sticks were then placed from each corner of the triangle to the midpoint of the length of the opposing stick. An additional triangle was created from the exposed corners. This process was repeated four times.

Possible Improvements:

Increase the thickness of each beam by putting multiple sticks together.

Structure 2: Triforce

Sate sticks, elastics, fishing line

Structure weight: 102g

Structure height: 40mm

Hypothesis: 2 people average

Fail: Lost 5mm as it was flattened.

Method of Construction:

All the beams in this design consisted of seven sticks tied together by three rubber bands, one on either end and one in the middle. These beams were then connected with rubber bands to create a triangle, this was then repeated directly on top and connected with rubber bands together and to the triangle below. Between the gap between the two layers three beams of half the length were placed diagonally creating three smaller triangles at each corner.

Possible Improvements:

Increase the thickness of each beam by putting multiple sticks together.

Structure 3: The Rebar

Only Paper

Structure weight: 156g

Structure height: 30mm

Hypothesis: 3 people average

Fail: Lost 10mm as it was flattened.

Method of Construction:

Repeatedly rolling paper as tight as possible then rolling 4 of the rolled papers within another paper. This was then rolled with another of the same size. Repeating this process three times to create the bridge. The three beams were then spread out at regular intervals to create a more stable platform for the tray and weights.

Possible Improvements:

Roll more paper and tighter rolls

Note: This was a group activity with Catherine Erzetic and Harris Paneras.
