en them. -- Moment of a force. (Mech.) (a) With respect to a point, the product of the intensity of the force into the perpendicular distance from the point to the line of direction of the force. (b) With respect to a line, the product of that component of the force which is perpendicular to the plane passing through…

An instrument for multiplying or increasing by repetition or accumulation the intensity of a force or action, as heat or electricity. It is particularly used to render such a force or action appreciable or measurable when feeble. See Thermomultiplier.

An instrument for determining and recording the different phases, as the intensity, velocity, etc., of a muscular contraction.

he international ohm. Ohm's law (Elec.), the statement of the fact that the strength or intensity of an electrical current is directly proportional to the electro-motive force, and inversely proportional to the resistance of the circuit.

A yellow pigment of various degrees of intensity, approaching also to red.

put to bodily uneasiness or anguish; to afflict with uneasy sensations of any degree of intensity; to torment; to torture; as, his dinner or his wound pained him; his stomach pained him. Excess of cold, as well as heat, pains us. Lock

An instrument for measuring sounds, as to their intensity, or the frequency of the vibrations.

An instrument for measuring the intensity of light, or, more especially, for comparing the relative intensities of different lights, or their relative illuminating power.

That branch of science which treats of the measurement of the intensity of light.

contrasted parts or directions in which a polar force is manifested; a point of maximum intensity of a force which has two such points, or which has polarity; as, the poles of a magnet; the north pole of a needle.

Characterized by intensity; deeply felt; pervading; overmastering; far-reaching; strongly impressed; as, a profound sleep. "Profound sciatica." Shak. Of the profound corruption of this class there can be no doubt. Milman.
