Why I Chose This Project I chose this

Why I Chose This Project �I chose this experiment because I find that my socks are always tearing. This made me wonder which of my socks was the most durable, and the cheapest so I wouldn’t have to spend a large sums of money on my socks even if they were fairly durable.

Materials �-Four pairs of socks �-Plywood plank �-Four sheets of sandpaper �-Measuring cup �-Meter stick �-Spring scale

Hypothosis �The Nike Sport Sock would be the best value for money. I believe this because not only does it seem just as strong as the other socks it is much cheaper than them too.

Procedure One (Toughness) �First I placed a wooden plank inside the first sock I would be testing, with the heel of the sock facing up. Next I hooked up a sander and attached a new sheet of sandpaper on the bottom of it. Then I placed the sander on the sock, midway between the heel and the toe.

Procedure One Cont. � Then I turned the sander on and using the same amount of pressure gently moved it up and down along the sock. I did this for thirty second intervals until the sock tore. I recorded the time and repeated this process again three times after switching to a new sheet of sandpaper every time.

Procedure Two (Strength) �First I cut a one inch by three in strip off of the heel of each sock. Then I attached the spring scale to my ceiling, and hooked the sock to the bottom of it. Then once I had it all set up, I had someone pull down slowly on the spring scale until the strip tore. I was standing right in front of the spring scale ready to read the final amount of weight the strip could take. Then I repeated this with the last three socks.

Procedure Three (Elasticity) �I started this test by cutting the elastic at the top of each sock off. Once I had all four strips of elastic I picked one and looped it around the hook at the bottom of the spring scale. I again had someone pull down on the elastic until it wasn’t able to stretch any more.

Procedure Three Cont. �I stood there with a yard stick getting the distance (in inches) that the sock could stretch. Once I was done with this process I repeated it with the last four socks.

Procedure Four (Absoption) �First I cut a one inch by one inch square form the heel of each of the socks. Then I filled up a measuring cup with onehundred milliliters. Then I held the sock in the water for thirty seconds, and then once that thirty seconds was over I let the sock drip for five seconds. I then recorded the amount of water left in the measuring cup.
