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.

Note:  The  time  of  oscillation  of  a  pendulum  is  independent  of
the  arc  of  vibration,  provided  this  arc  be  small

{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  rodsof
different  metals.

{Compound  pendulum},  an  ordinary  pendulum;  --  so  called  as
being  made  up  of  different  parts  and  contrasted  with
simple  pendulum.

{Conical}  or  {Revolving},  {pendulum},  a  weight  connected  by  a
rod  with  a  fixed  point;  and  revolving  in  a  horizontal
cyrcle  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}  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

Conic  \Con"ic\,  Conical  \Con"ic*al\,  a.  [Gr.  ?:  cf  F.  conique
See  {Cone}.]
1.  Having  the  form  of  or  resembling,  a  geometrical  cone;
round  and  tapering  to  a  point,  or  gradually  lessening  in
circumference;  as  a  conic  or  conical  figure;  a  conical
vessel.

2.  Of  or  pertaining  to  a  cone;  as  conic  sections.

{Conic  section}  (Geom.),  a  curved  line  formed  by  the
intersection  of  the  surface  of  a  right  cone  and  a  plane.
The  conic  sections  are  the  parabola,  ellipse,  and
hyperbola.  The  right  lines  and  the  circle  which  result
from  certain  positions  of  the  plane  are  sometimes  though
not  generally  included.

{Conic  sections},  that  branch  of  geometry  which  treats  of  the
parabola,  ellipse,  and  hyperbola.

{Conical  pendulum}.  See  {Pendulum}.

{Conical  projection},  a  method  of  delineating  the  surface  of
a  sphere  upon  a  plane  surface  as  if  projected  upon  the
surface  of  a  cone;  --  much  used  by  makers  of  maps  in
Europe.

{Conical  surface}  (Geom.),  a  surface  described  by  a  right
line  moving  along  any  curve  and  always  passing  through  a
fixed  point  that  is  not  in  the  plane  of  that  curve.

From  WordNet  r  1.6  [wn]:

conical
adj  :  relating  to  or  resembling  a  cone;  "conical  mountains";
"conelike  fruit"  [syn:  {conic},  {conelike},  {cone-shaped}]
