Assign Task4[edit]

Determine the failing force of Spaghetti and Linguine.

Week4 Activities[edit]

Week4 Narrative[edit]

This week I worked on finding the force a noodle could withstand in relation to its length. This could be used to make stronger noodle bridges and help understand torque force.
My experiment goes as follows:

  1. Accurately measure and cut one spaghetti and linguine noodle to 23cm, 15cm, 7cm.
  2. Line up 5-8 noodles with the measured noodle. Then quickly cut through them all with authority until you have a large, even, number of them. As seen in Figure1.
  3. Then mark each test piece 1cm away from the bottom.
  4. To test torque and compression strengths I first zeroed my food scale when it read less than zero. I then held each piece by the 1cm mark. After that I applied force as slow as possible into a food scale (set to grams) through the noodle until it snapped and recorded that force. As seen in Torque vs. Compression.



FAILING FORCE DATA

Data analysis: While my data was useful after the experiment I learned a few things I could have done better. One, I should have remembered that T = f*cosθ. While I was calculating the force, my experiment did not factor in the angle measure at the point of failure. Also, if I would have used a bigger test sample my numbers would be more accurate and less dependent on individual condition of each noodle. One thing I noticed after doing the experiment over and over again is that each noddle is different. The noodles that failed easier than the average often had a defect or were slightly thinner and vise versa. One thing I learned from This experiment is that the force required to bend the noodle is very close to its point of failure. I noticed this because doing one of my tests I repeatedly bounced the noodle on the scale and the force did not change. Then bending it just slightly more broke it and the force would only increase by a gram or two.
