Fw: A question of Scale Weight vs Springs [TANKS]

["Chrysanthos Kanellopoulos" <xchrysk-at-otenet.gr>]

exactly Amir, when going from 1:4 to 1:6  the scale is not doubled and the volume is not multipied 8 times. The ratio of the two scales is 3:2  and ratio of volumes is  3.37 :1 or in integer numbers 27:8 = cube of 3 : cube of 2 = (3 x 3 x 3) : (2 x 2 x 2),  or so I think.

I therefore, divided the .935 with 3.375, not with 8.

> In scale 1:1 a Tiger weighs 60 tons
> in scale 1:2 = 60 : 8 = 7.5 tons
> in scale 1:4 = 7.5  : 8 = 0.935 tons
> in scale 1:6 a steel Tiger SHOULD weigh 0.935 : 3.37 = 278 kgrs.
Hang on, there's a missing step

1:1 is 60
1:2 is 7.5
1:4 is .935
1:6 is ____

Careful, going from 2 -> 4 isn't the same as going from 4 -> 6.  The
important concept is that
volume is cubic (3 dimensions).
