- During Week 5. we had one week of prior experience working with the box and the sand. We modified our approach and decided to incorporate cut paper into the design of the wall. The motivation was in an attempt to create more friction by cutting the paper, but it was later found out that extra friction will not be created, since the paper is extremely thin. Even with the new found information, the strip idea was kept, since the technique seemed effective.
- A total of 5 pieces of paper were used. The middle three layers had strips cut into them, and the bottom and top layers were left uncut. Layers two and three were cut into horizontal strips and had vertical strips added in addition to the horizontal ones. The idea was to place the paper into different patterns to find out which arrangement was the most effective.
- Each layer was separated by 2.2 inches of sand. In addition, the portion of paper left uncut was 6.5 inches (that portion was folded over onto the next layer). The spacing between the uncut portion of paper and the strips was 2.5 inches.
- The wall held 310 pounds. A failure weight was not achieved, since no actual failure occurred.
Image 1: Wall holding the 310 pounds. Structure did not fail even with a layer cut.
Image 2: Close up of wall with cut layer and 20 pound weight on top. No failure with cut layer.
Post Lab
- The group thought of ideas to reduce the amount of paper. Too much paper was still being used in the wall. Some strips will possibly be eliminated or new layering techniques will be tried next week.
