95
CHAPTER 7

• Succeeding in the Classroom

96
7.2 Attitude

• Success in an engineering curriculum depends
  largely on a students attitude and work ethic

  student will most likely fail
• Keep an open mind, and be willing to work with
  the professor in order to best understand the
  material

97
7.3 Goals

• Work lots of problems, not just the minimum
  amount for homework
• Study in groups

99
7.5 Test Taking

• Obtain past exams
• Ask professor for practice exams
• Work problems in book
• Start with problems you know how to do, then work
  on the harder problems
• Skim test first, to see what will basically be
  covered

100
7.6 Making the Most of Your Professor

• Dont wait until the end of the semester to go
  for help
• If you make yourself visible in class and during
  office hours, the professor may remember you
  while grading
• Teaching is not professors only responsibility,
  often the are researchers and advisors as well,
  so give them the benefit of the doubt

101
7.7 Learning Styles

• Each persons brain is unique to him or her
• Proper nutrition, stress, drugs and alcohol are
  some of the factors that can affect a developing
  brain

• Sketches, tables, graphs, computer generated
  drawings, blueprints are various ways in which
  engineers communicate via visual mediums

121
9.3 Sketching

• Although most final drawings are computer
  generated, initial and freehand sketches are
  vital to the design process
• Freehand does not mean messy. Sketches should
  display an adequate amount of detail, and any
  pertinent notes/comments pertaining to the
  drawing
• For instance, if a line is supposed to be
  straight, make it as straight as possible. A
  square will not pass for a circle.

122
9.7 Graphical Communication

• Oblique and isometric drawings are 3D and general
• Orthographic drawings are 2D, more detailed, and

  equal. The leadership moves with the situation
  to the worker with the most expertise in a given
  subject

• Engineering design is the process of devising a
  system, component, or process to meet desired
  needs. It is a decision making process in which
  the basic sciences and mathematics and
  engineering sciences are applied to convert
  resources optimally to meet a stated objective.
  Among the fundamental elements of the design
  process are the establishment of objectives and
  criteria, synthesis, analysis, construction, and
  testing.
