For the paper compression test we rolled the construction paper into a tube that was 8" long with approximately 1" diameter we placed it in the compressor. The maximum loading for the construction paper roll is about three and a quarter pounds of pressure. For the straw compression test, we placed the straw into a one hole stopper to stabilize it. We then applied weight to it and found out that the maximum loading for the straw is approximately one and a half pounds of pressure. There are two forces happening in the straw; compression and bending. Bending forces arise in a compression member when the slenderness ratio is very high. We then calculated the slenderness ratio by multiplying the diameter of the material by the length of the material. The slenderness ratio for the straw came out to 1/8 to 7 1/2.
