Compensation pendulum
(gcide) | Compensation \Com`pen*sa"tion\, n. [L. compensatio a weighing, a
balancing of accounts.]
1. The act or principle of compensating. --Emerson.
[1913 Webster]
2. That which constitutes, or is regarded as, an equivalent;
that which makes good the lack or variation of something
else; that which compensates for loss or privation;
amends; remuneration; recompense.
[1913 Webster]
The parliament which dissolved the monastic
foundations . . . vouchsafed not a word toward
securing the slightest compensation to the
dispossessed owners. --Hallam.
[1913 Webster]
No pecuniary compensation can possibly reward them.
--Burke.
[1913 Webster]
3. (Law)
(a) The extinction of debts of which two persons are
reciprocally debtors by the credits of which they are
reciprocally creditors; the payment of a debt by a
credit of equal amount; a set-off. --Bouvier.
--Wharton.
(b) A recompense or reward for some loss or service.
(c) An equivalent stipulated for in contracts for the sale
of real estate, in which it is customary to provide
that errors in description, etc., shall not avoid, but
shall be the subject of compensation.
[1913 Webster]
Compensation balance, or Compensated balance, a kind of
balance wheel for a timepiece. The rim is usually made of
two different metals having different expansibility under
changes of temperature, so arranged as to counteract each
other and preserve uniformity of movement.
Compensation pendulum. See Pendulum.
Syn: Recompense; reward; indemnification; consideration;
requital; satisfaction; set-off.
[1913 Webster] |
Compensation pendulum
(gcide) | Pendulum \Pen"du*lum\, n.; pl. Pendulums. [NL., fr. L.
pendulus hanging, swinging. See Pendulous.]
A body so suspended from a fixed point as to swing freely to
and fro by the alternate action of gravity and momentum. It
is used to regulate the movements of clockwork and other
machinery.
[1913 Webster]
Note: The time of oscillation of a pendulum is independent of
the arc of vibration, provided this arc be small.
[1913 Webster]
Ballistic pendulum. See under Ballistic.
Compensation pendulum, a clock pendulum in which the effect
of changes of temperature of the length of the rod is so
counteracted, usually by the opposite expansion of
differene metals, that the distance of the center of
oscillation from the center of suspension remains
invariable; as, the mercurial compensation pendulum, in
which the expansion of the rod is compensated by the
opposite expansion of mercury in a jar constituting the
bob; the gridiron pendulum, in which compensation is
effected by the opposite expansion of sets of rods of
different metals.
Compound pendulum, an ordinary pendulum; -- so called, as
being made up of different parts, and contrasted with
simple pendulum.
Conical pendulum or Revolving pendulum, a weight
connected by a rod with a fixed point; and revolving in a
horizontal circle about the vertical from that point.
Pendulum bob, the weight at the lower end of a pendulum.
Pendulum level, a plumb level. See under Level.
Pendulum wheel, the balance of a watch.
Simple pendulum or Theoretical pendulum, an imaginary
pendulum having no dimensions except length, and no weight
except at the center of oscillation; in other words, a
material point suspended by an ideal line.
