GENERAL ANALYSIS PROCEDURE (1) 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. The problem statement summarizes the given information including all input data provided to solve the problem. The problem statement also states what is to be determined by performing the analysis.

GENERAL ANALYSIS PROCEDURE (2) 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. The diagram should show all given information contained in the problem statement such as geometry, applied forces, energy flows, mass flows, electrical currents, temperatures, or other physical quantities as required. Hint: Draw it big enough so you can see it and understand all the variables you have labeled on the diagram. Graph paper, straight edge, ruler are helpful.

GENERAL ANALYSIS PROCEDURE (3) 3. Assumptions: Engineering analysis almost always involves some assumptions. Assumptions are special assertions about the physical characteristics of the problem that simplify or refine analysis. A very complex analytical problem would be difficult or even impossible to solve without making some assumptions. Hint: Sometimes referred to as ‘Givens’. Textbook problems often reverse the ‘Givens’ with the ‘Finds / Calculate’.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
