    Mechanisms   and   Electric   Circuits   is   offered   in   two   serial   modules,   including   laboratory   and   workshop   practice,   and   a   team   project   to   expose   students   to   the   concept   of   system   integration   involving   electrical   and  mechanical  systems.  The  electrical  module  provides  an  introduction  to  dc  circuits,  with  an  analysis  of   dc  circuits  used  in  control,  measurement  and  instrumentation  systems.  The  mechanism  module  provides  an   introduction  to  machine  components  such  as  belts,  pulleys,  gears,  and  simple  linkages.  The  laboratory  and   workshop  component  introduces  students  to  hands-­‐on  practice  in  basic  laboratory  instruments,  tools  and   safety  procedures.  A  team  project  involves  the  construction,  assembly  and  testing  of  a  simple  mechanism.   PREREQUISITES:  

Level   III   Physics   or   Physics   1051   (which   may   be   taken   concurrently)   and   Mathematics  1000  (which  may  be  taken  concurrently).  

CREDIT  VALUE:                                3  credits    

COURSE  DESCRIPTION   The broad aims of the course are to teach students 1) to learn the concepts and principles that apply to electric circuit analysis, and 2) to develop problem-solving skills by emphasizing the application of conceptual understanding  to  the  solution  of  electric  circuit  problems.

Unauthorized   use   of   the   above   aids   or   devices   during   tests   and   examinations   will   be   considered   as   an   academic  offence.           ACADEMIC  INTEGRITY  AND  PROFESSIONAL  CONDUCT     Cheating  on  tests  and  examinations,  or  copying  laboratory  reports  will  be  dealt  with  in  accordance  with  the   procedures  outlined  under  Academic  Misconduct  in  the  University  Calendar.       Students  are  expected  to  conduct  themselves  in  all  aspects  of  the  course  at  the  highest  level  of  academic   integrity.  Any  work  for  which  the  student  is  claiming  credit  should  be  original  work  and  the  source  of  any   submitted   material   which   is   not   original   must   be   given   proper   credit.   Any   student   found   to   commit   academic  misconduct  will  be  dealt  with  according  to  the  Faculty  and  University  practices.  More  information   is  available  at  www.engr.mun.ca/undergrad/academicintegrity.     Students  are  encouraged  to  consult  the  Faculty  of  Engineering  and  Applied  Science  Student  Code  of   Conduct  at  http://www.engr.mun.ca/policies/codeofconduct.php  and  Memorial  University’s  Code  of  Student   Conduct  at  http://www.mun.ca/student/home/conduct.php.  

  INCLUSION  AND  EQUITY  

Students   who   require   physical   or   academic   accommodations   are   encouraged   to   speak   privately   to   the   instructor   so   that   appropriate   arrangements   can   be   made   to   ensure   full   participation   in   the   course.     All   conversations  will  remain  confidential.     The  university  experience  is  enriched  by  the  diversity  of  viewpoints,  values,  and  backgrounds  that  each   class  participant  possesses.    In  order  for  this  course  to  encourage  as  much  insightful  and  comprehensive   discussion  among  class  participants  as  possible,  there  is  an  expectation  that  dialogue  will  be  collegial  and   respectful  across  disciplinary,  cultural,  and  personal  boundaries.     STUDENT  ASSISTANCE   Student  Affairs  and  Services  offers  help  and  support  in  a  variety  of  areas,  both  academic  and  personal.     More  information  can  be  found  at  www.mun.ca/student.
