EGR 231  Engineering Statics    3 credits   
Description:
An introduction to engineering statics.  Topics include vectors, resultants, equilibrium, structural analysis, centroids, friction, and moment of inertia.  This course focuses on application and rigorous problem solving with these topics. 

Objectives:
To learn to apply equilibrium to the determination of forces.
To analyze stationary bodies under the action of forces.
To improve student's mathematic and problem solving abilities
 

Meets:  MWF from 1:00 to 1:50 in Science 118

Text: Beer and Johnston,  Vector Mechanics for Engineers, Statics & Dynamics, 9^th ed.,
          McGraw Hill            

 
Prerequisite:
    Math 160

 
Homework:
Homework assignments will be given daily and be collected at the start of the second lecture period following the assignment.  It is expected that students will attempt homework in a timely manner, so that they may ask questions at the very next lecture time.  Late homework will generally not be accepted for grading, unless prior arrangements have been made with a good (or creative) reason.

Portfolio:
All students are expected to keep a course portfolio.  It should contain your notes, corrected homework and quizzes, and other handouts provided during the course and should be organized in a manner that makes it easy to locate your work.

Quizzes and Tests:
Testing will be completed by use of five tests and a examination.

Tests are scheduled on the course syllabus and will be 50 minutes in length.

The final examination (date and time yet to be scheduled) will be given during finals week.

Expect exams to be given as closed book, closed computer tests.  You are expected to have a scientific or graphing calculator for use during tests and exams.

Grading:
The weighting that will be used to determine the course grade is shown in the following table:
            Homework .........................15%
            Portfolio................... ..........5%
            Tests...………………….....60%
            Final Examination…....…….20%

Because its better to be a big fish in a big pond than a little fish in a little pond. . . or something like that.
