Objectives:

 

In accordance with the University of Evansville Mission educational objectives that students acquire a depth of knowledge in one or more disciplines of their choice and master communication, organization, and critical thinking skills, the course seeks to help students develop the ability to analyze and solve a variety of practical problems involving static force systems in both two and three dimensions, equilibrium, equivalent systems of forces, friction, and section and volume properties.  Algebraic and vector methods will be used to introduce the analysis and behavior of basic structural systems such as trusses, beams, frames, and machines.

 

Methods:

 

Class attendance is expected, as are participation in class discussion and timely completion of homework.

 

Text:

 

Vector Mechanics for Engineers – Statics 7th Edition by Ferdinand P. Beer, E. Russell Johnston, Jr., and Elliot R. Eisenberg, McGraw Hill, 2004.

 

Grading:

 

The course grade will be determined by weighting the homework as 20% of the grade, each of the three hour exams as 15%, and the two-hour comprehensive final examination as 35%.  A 5% bonus will be made available for participation in extra-credit activities.

 

Honor Code:

 

All students are expected to be aware of and to adhere to the University Honor Code.

 

Schedule:

 

A tentative schedule of sessions, including reading assignments, is shown below.  Students will be expected to have read the indicated sections of the textbook prior to coming to class.

 

 

 

 

Note on Homework:

 

All homework is to be submitted on engineering paper, which is available in the University Bookstore.  Each problem should start on a new page.  Your solutions should follow the following format:

 

I.                     Problem Statement

The problem statement is a summary of the known information, not a verbatim copy of the original problem.

 

II.                   Requirements

List the quantities that must be determined.

 

III.                 Solution

 

A.       Schematic with Given Data

A simplified system should be sketched which clearly identifies all pertinent information.  Define a coordinate system if appropriate.  Information on the sketch should include all geometric data given, any equation or subscript used in your equations, force direction and angles, systems and control volumes, etc.  More than one schematic may be required.

 

B.       Assumptions

List all assumptions you can make before you begin the solution (i.e., frictionless plane, component’s weight is small relative to other forces, reversible process, insulated container, etc.).

 

C.      Development of Mathematical Description

Write the mathematical equations in symbolic form.  Generally the mathematical description is presented in symbolic form because it is easy to create simplified forms of the equations without the numeric values.  This form of the solution is of great value in programming spreadsheets, writing a computer program, or crunching numbers.

 

                  IV            Calculation of the Answer

At this point, numeric values, with appropriate units, are substituted into the math model.  Computations are then performed and consistent units should be shown.
