2. General Analysis Procedure  The following procedure is recommended for exams and homework

3. General Analysis Procedure  The general analysis procedure consists of the following seven steps. 1. Problem Statement The problem statement is a written description of the analytical problem to be solved. It should be written clearly, concisely. and logically. 2. 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.

4. General Analysis Procedure 3. 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. 4. 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.

5. General Analysis Procedure 5. 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. 6. 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.

6. General Analysis Procedure 7. Discussion After the solution has been thoroughly checked and corrected, discuss the result.  The discussion may include an assessment of the assumptions
