Calculator Policy

• What is the calculator policy? What calculators
  may I bring to the exam?
• Only models of calculators approved by NCEES are
  permitted in the exam room. No other models of
  calculators are permitted in the exam room. The
  following are the only calculators that will be
  permitted in the exam room for the 2010 exam
  administrations.

Calculator Policy

• Casio All fx-115 models. Any Casio calculator
  must contain fx-115 in its model name. Examples
  of acceptable Casio fx-115 models include (but
  are not limited to)
• fx-115 MS
• fx-115 MS Plus
• fx-115 MS SR
• fx-115 ES
• Hewlett Packard The HP 33s and HP 35s models,
  but no others.

General Analysis Procedure

• The following procedure applies for exams and
  homework

General Analysis Procedure

• The general analysis procedure consists of the
  following seven steps.
• Problem Statement The problem statement is a
  written description of the analytical problem to
  be solved. It should be written clearly,
  concisely. and logically.
• Diagram The diagram is a sketch. drawing. or
  schematic of the system being analyzed.
  Typically. it is a simplified pictorial
  representation of the actual system, showing only
  those aspects of the system that are necessary to
  perform the analysis.

• Imagine the Flash Light has two lamps.

General Analysis Procedure

1. Assumptions Engineering analysis almost always
   involves some assumptions. Assumptions are
   special assertions about the physical
   characteristics of the problem that simplify or
   refine the analysis.
2. Governing Equation. All physical systems may be
   described by mathematical relations. Governing
   equations are those mathematical relations that
   specifically pertain to the physical system being
   analyzed.

General Analysis Procedure

• Calculations In this step. the solution is
  generated
• First, the solution is developed algebraically
  as far as possible.
• Then numerical values of known physical
  quantities are substituted for the corresponding
  algebraic variables.
• Solution Check This step is crucial. Immediately
  after obtaining the result, examine it carefully.
  Using established knowledge of similar analytical
  solutions and common sense, try to ascertain
  whether the result is reasonable.

10
General Analysis Procedure

• Discussion After the solution has been thoroughly
  checked and corrected, discuss the result.
• The discussion may include an assessment of the
  assumptions, a summary of the main conclusions, a
  proposal on how the result may be verified
  experimentally in a laboratory,
• or a parametric study demonstrating the
  sensitivity of the result to a range of input
  parameters.
