Levels   are   designed   for   which   of the   following   purposes? 1. 2. 3. 4. To   prove   whether   a   plane   is   in the   true   vertical   or   true horizontal To   prove   whether   a   surface   is in   the   true   vertical   or   true horizontal Both   land   2   above To  remove  the  rough  spots  on surfaces 2-2. Which   of   the   following   types   of levels   is   used   mostly   in   the construction    industry? 1.   The   machinist's   level 2.   The   line   level 3.   The   iron   bench   level 4.   The   striding   level 2-3. What   feature   on   a   machinist's level   increases   its   accuracy   and sensitivity? 1.   Its   metallic   coating 2.   Its   extra   large   vial 3.   Its   grooved   bottom 4.   Its   light   weight 2-4. Which   of   the   following   levels   has a   main   vial   that   is   used   to determine   true   horizontal,   and   two smaller   vials   that   are   used   to determine   true   vertical? 1.   The   machinist's   level 2.   The   striding   level 3.   The   line   level 4.   The   master   precision   level 2-5. Which   of   the   following   levels   is used   to   span   existing   cabling, piping,   or   similar   obstructions? 1.   The   master   precision   level 2.   The   iron   bench   level 3.   The   striding   level 4.   The   machinist's   level 2-6. The   carpenter's   level   has   three vials.   One   vial   is   mounted vertically   and   another   is   mounted horizontally.   The   third   vial   is mounted  at  what  angle? 1.  35  degrees 2.  45  degrees 3.  55  degrees 4.  90  degrees 2-7. A  plumb  bob  is  used  for  which  of the   following   purposes? 1.   To   establish   a   true   vertical transfer   and   line-up   reference point 2.   To   take   readings   or   soundings in   tanks   or   voids 3.  Both  2  and  3  above 4.  To  measure  the  distance  between two   horizontal   points 2-8. Plumb  bobs  are  used  by  which  of the   following   people? 3.   Maintenance   technicians 4.   All   of   the   above 1.   Carpenters 2.   Surveyors 2-9. The  surveyor's  brass  plumb  bob  may be   either   a   spool   type   or   what other   type? 1.   An   adjustable   cap   type 2.   A   permanent   cap   type 3.   A   flexible   cap   type 4.   A   reverse   cap   type 7
