POISSON NUMBER

The reciprocal of the Poisson ratio.

MOHM

A unit of mechanical mobility, equal to the reciprocal of 1 mechanical ohm.

MODULUS OF DECAY

The time required for the amplitude of oscillation of an underdamped harmonic oscillator to drop to 1/e of its initial value; the reciprocal of the damping factor.

SHEAR RATE

Rate at which adjacent layers of fluid move with respect to each other, usually expressed as reciprocal seconds.

LANDING COMPASS

A compass taken ashore so as to be unaffected by deviation. If reciprocal bearings of the landing compass and the magnetic compass on board are observed, the deviation of the latter can be determined.

CARRIER FREQUENCY

1. The frequency of the unmodulated fundamental output of a radio transmitter. 2. In a periodic carrier, the reciprocal of its period. The frequency of a periodic pulse carrier often is called PULSE REPETITION FREQUENCY

COLOGARITHM

The logarithm of the reciprocal of a number, or the negative logarithm. The sum of the logarithm and cologarithm of the same number is zero. The addition of a cologarithm accomplishes the same result as the subtraction of a logarithm.

FLATTENING

The ratio of the difference between the equatorial and polar radii of the earth to its equatorial radius. The flattening of the earth is the ellipticity of the spheroid. The magnitude of the flattening is sometimes expressed as the numerical value of the reciprocal of the flattening. Also called COMPRESSION.

SPECIFIC VOLUME

The volume of a substance per unit mass; the reciprocal of density.

RECIPROCAL

In a direction 180° from a given direction.
