Unformatted text preview: 50x0.19635mm^2=9.81748. Since both are supporting equal weight, we can set the breaking force of the 50 wires equal to the breaking force of the 1 wire, 9.81748=1x(z/2)^2 x pi. We solve for z, or the diameter, and get -3.536 and 3.536. Since our measurement can't be negative, the diameter of the single steel wire is 3.536mm. The length of the snake is equal to eight worms laid end to end. The cross sectional area of the snake is eight worms laid side-by-side divided by two, squared, and then multiplied by pi - (8 worms/2)^2 x pi = 16pi. If we multiply the cross sectional area by the length, which is 8 worms laid end to end, then we get the volume of the snake in the measurement of worms, 16pi x 8 = 402.124 worms. The snake would have to eat 402.124 worms to double its weight....
