The wheel flange presses against the side of the curved rail so the " contact point " between rail and wheel moves a few millimeters outwards, making the effective diameter of the outer wheel temporarily larger, and equally opposite : the effective diameter of the inner wheel effectively becomes temporarily smaller.

:* Thirdly, with wheels, the driving force is at the central axle-so the torque requirement from the motor would change as the wheel rotates and alternately raises and lowers the body of the car and the effective diameter of the wheel changes-this would clearly be a bad thing.

The best fit shape model as measured by the Arecibo team has parameters a / b = 1.7 ?0.1, a / c = 1.6 1.9, with an a-axis of 113 ?10 km; this gives an effective diameter of 79 ?10 km, which is in agreement with the HST study by Tanga " et al . " in 2003.

"' Variomatic "'is the continuously variable transmission ( CVT ) of the DAF, originally developed by Hub van Doorne : It is a stepless, fully automatic transmission consisting of a " V " shaped drive belt and two pulleys, each of two cones, whose effective diameter can be changed so that the " V " belt runs nearer the spindle or nearer the rim, depending on the separation of the cones.
