- Seven different tires were chosen and cut into sections with uniform
- A box was built with two pieces of wood attached to the bottom as
a place to attach the tire-ski, and a place to pull (located approximately
at the center of mass) on a massless, frictionless string.
- The tire's static coefficient of friction was measured repeatedly
and the average values were tabulated on an icy road near Fox, Alaska.
It was 20 degrees Farenheit outside when the measurements were made, and
the weight used was uniform.
- We compared the results of the friction test to our hypothesis and
made generalizations about which tires perform better on icy, snowy conditions.
- We went sledding.
