In technical drawing, an oval is a figure constructed from two pairs of arcs, with two different radii (see image on the right).

The turns at each end of the track had different radii, like Darlington Speedway has today.

"Besides making different radius turns - short, medium and long arcs - run straight to be sure the tips don't swim," said Kashiwa.

Combined with the planets' different radii, this means Mars is nearly three times "rougher" than Earth.

A typical example would be the electric field surrounding two conducting spheres of different radii.

The range includes a wider variety of points and crossings, at different radii.

However, the correction is slightly worse than the asymmetric corrector with four different radii.

Try drawing circles of different radii that don't hit those points.

The polynomial has all its zeros lying on two half-circles of different radii.

Since the terraces have different radii of rotation, alien species native to multiple gravity levels can be accommodated.
