In his 1955 book A Night to Remember, Walter Lord described Titanic as assuming an "absolutely perpendicular" position before its final plunge.

This apparent contradiction is caused by the perpendicular position of the grain boundaries; the boundary diffusion factor is excluded, and material transport is correspondingly reduced.

When an ion beam is focused on a particular spot, the metal flakes in the paint rotate to a perpendicular position and the paint darkens.

The mounting of spare wheels is totally different at the rear of the truck in a perpendicular position.

As they watched, one section unfolded from the bottom to a perpendicular position, and another unfolded from that, parallel to the ship.

At once the sapling shot up, and after that gave no more trouble, remaining in the decorous and perpendicular position in which nature had intended it to grow.

The sea anchor remained just under the surface of the ocean in a perpendicular position.

After river traffic has passed, it is hand-cranked again until it has been returned to its perpendicular position across the river.

The leading engine was derailed, and thrown along- side the line, while its tender was left in an almost perpendicular position.

Tori initiates the throw by stepping to the same side as Uke's advance, and rotating 90 degrees to a perpendicular position with Uke.
