Engineering  is  the  application  of  scienti1ic,  economic,  social,  and  practical  knowledge  in  order  to  design,  build,  and  maintain  structures,  machines,  devices,  systems,  materials  and  processes.  It  may  encompass  using  insights  to  conceive,  model  and  scale  an  appropriate  solution  to  a  problem  or  objective.  The  discipline  of  engineering  is  extremely  broad,  and  encompasses  a  range  of  more  specialized  1ields  of  engineering,  each  with  a  more  speci1ic  emphasis  on  particular  areas  of  technology  and  types  of  application.

The  application  of  science  to  the  optimum  conversion  of  the  resources  of  nature  to  the  uses  of  humankind.  The  1ield  has  been  de1ined  by  the  Engineers  Council  for  Professional  Development,  in  the  United  States,  as  the  creative  application  of  “scienti1ic  principles  to  design  or  develop  structures,  machines,  apparatus,  or  manufacturing  processes,  or  works  utilizing  them  singly  or  in  combination;  or  to  construct  or  operate  the  same  with  full  cognizance  of  their  design;  or  to  forecast  their  behaviour  under  speci1ic  operating  conditions;  all  as  respects  an  intended  function,  economics  of  operation  and  safety  to  life  and  property.”

1.   Identify  and  have  an  understanding  of  the  Mechanical  Engineering  profession.

2.   Understand  what  society  and  industry  expects  from  Mechanical  Engineers.

3.   Understand  the  complexities  associated  with  diverse  areas  on  Mechanical  Engineering.

4.   Run  selected  software  packages,  which  are  representa-­‐tive  of  the  Mechanical  Engineering  program  (e.g.,  MATLAB  and  Arduino  IDE),  on  your  personal  computers

At  the  end  of  this  course,  you  will  be  able  to:

Example operations and important observations ...

MATLAB:

understands the “standard” language of engineers

automatically assigns the result to a variable “ans”

“knows” math functions

uses “(...)” to pass arguments of functions

expects angles to be given in radians (SI)

gives much freedom in building expressions

Intro:      What  Arduino  is  and  why  you'd  want  to  use  it.

Arduino  is  a  tool  for  making  computers  that  can  sense  and  control  more  of  the  physical  world  than  your  desk-­‐top  computer.  It's  an  open-­‐source  physical  computing  platform  based  on  a  simple  microcontroller  board,  and  a  development  environment  for  writing  software  for  the  board.  More  information  available  on-­‐line  ...
