1. The act of rubbing the surface of one body against that of
another; attrition; in hygiene, the act of rubbing the
body with the hand, with flannel, or with a brush etc., to
excite the skin to healthy action.
[1913 Webster]
2. (Mech.) The resistance which a body meets with from the
surface on which it moves. It may be resistance to sliding
motion, or to rolling motion.
[1913 Webster]
3. A clashing between two persons or parties in opinions or

[1913 Webster]
Angle of friction (Mech.), the angle which a plane onwhich
a body is lying makes with a horizontal plane,when the
hody is just ready to slide dewn the plane.
Note: This angle varies for different bodies, and for planes
of different materials.
Anti-friction wheels (Mach.), wheels turning freely on
small pivots, and sustaining, at the angle formed by their
circumferences, the pivot or journal of a revolving shaft,
to relieve it of friction; -- called also {friction
wheels}.
Friction balls, or
Friction rollers, balls or rollers placed so as to receive
the pressure or weight of bodies in motion, and relieve
friction, as in the hub of a bicycle wheel.
Friction brake (Mach.), a form of dynamometer for measuring
the power a motor exerts. A clamp around the revolving
shaft or fly wheel of the motor resists the motion by its
friction, the work thus absorbed being ascertained by
observing the force required to keep the clamp from
revolving with the shaft; a Prony brake.
Friction chocks, brakes attached to the common standing
garrison carriages of guns, so as to raise the trucks or
wheels off the platform when the gun begins to recoil, and
prevent its running back. --Earrow.
Friction clutch, Friction coupling, an engaging and
disengaging gear for revolving shafts, pulleys, etc.,
acting by friction; esp.:
(a) A device in which a piece on one shaft or pulley is so
forcibly pressed against a piece on another shaft that
the two will revolve together; as, in the
illustration, the cone a on one shaft, when thrust
forcibly into the corresponding hollow cone b on the
other shaft, compels the shafts to rotate together, by
the hold the friction of the conical surfaces gives.
(b) A toothed clutch, one member of which, instead of
being made fast on its shaft, is held by friction and
can turn, by slipping, under excessive strain or in
starting.
Friction drop hammer, one in which the hammer is raised for
striking by the friction of revolving rollers which nip
the hammer rod.
Friction gear. See Frictional gearing, under
Frictional.
Friction machine, an electrical machine, generating
electricity by friction.
Friction meter, an instrument for measuring friction, as in
testing lubricants.
Friction powder, Friction composition, a composition of
chlorate of potassium, antimony, sulphide, etc, which
readily ignites by friction.
Friction primer, Friction tube, a tube used for firing
cannon by means of the friction of a roughened wire in the
friction powder or composition with which the tube is
filled.
Friction wheel (Mach.), one of the wheels in frictional
gearing. See under Frictional.

Frictional electricity (gcide) | Electricity \E`lec*tric"i*ty\ ([=e]`l[e^]k*tr[i^]s"[i^]*t[y^]),
n.; pl. Electricities ([=e]`l[e^]k*tr[i^]s"[i^]*t[i^]z).
[Cf. F. ['e]lectricit['e]. See Electric.]
1. (Physics) a property of certain of the fundamental
particles of which matter is composed, called also
electric charge, and being of two types, designated
positive and negative; the property of electric charge on
a particle or physical body creates a force field which
affects other particles or bodies possessing electric
charge; positive charges create a repulsive force between
them, and negative charges also create a repulsive force.
A positively charged body and a negatively charged body
will create an attractive force between them. The unit of
electrical charge is the coulomb, and the intensity of
the force field at any point is measured in volts.
[PJC]
2. any of several phenomena associated with the accumulation
or movement of electrically charged particles within
material bodies, classified as static electricity and
electric current. Static electricity is often observed
in everyday life, when it causes certain materials to
cling together; when sufficient static charge is
accumulated, an electric current may pass through the air
between two charged bodies, and is observed as a visible
spark; when the spark passes from a human body to another
object it may be felt as a mild to strong painful
sensation. Electricity in the form of electric current is
put to many practical uses in electrical and electronic
devices. Lightning is also known to be a form of electric
current passing between clouds and the ground, or between
two clouds. Electric currents may produce heat, light,
concussion, and often chemical changes when passed between
objects or through any imperfectly conducting substance or
space. Accumulation of electrical charge or generation of
a voltage differnce between two parts of a complex object
may be caused by any of a variety of disturbances of
molecular equilibrium, whether from a chemical, physical,
or mechanical, cause. Electric current in metals and most
other solid coductors is carried by the movement of
electrons from one part of the metal to another. In ionic
solutions and in semiconductors, other types of movement
of charged particles may be responsible for the observed
electrical current.
[PJC]
Note: Electricity is manifested under following different
forms: (a)
Statical electricity, called also
Frictional electricity or Common electricity, electricity
in the condition of a stationary charge, in which the
disturbance is produced by friction, as of glass, amber,
etc., or by induction. (b)
Dynamical electricity, called also
Voltaic electricity, electricity in motion, or as a current
produced by chemical decomposition, as by means of a
voltaic battery, or by mechanical action, as by
dynamo-electric machines. (c)
Thermoelectricity, in which the disturbing cause is heat
(attended possibly with some chemical action). It is
developed by uniting two pieces of unlike metals in a bar,
and then heating the bar unequally. (d)
Atmospheric electricity, any condition of electrical
disturbance in the atmosphere or clouds, due to some or
all of the above mentioned causes. (e)
Magnetic electricity, electricity developed by the action
of magnets. (f)
Positive electricity, the electricity that appears at the
positive pole or anode of a battery, or that is produced
by friction of glass; -- called also {vitreous
electricity}. (g)
Negative electricity, the electricity that appears at the
negative pole or cathode, or is produced by the friction
of resinous substance; -- called also resinous
electricity. (h)
Organic electricity, that which is developed in organic
structures, either animal or vegetable, the phrase animal
electricity being much more common.

the paper to engage with the sprockets of the feed mechanism.
