COURSE PRE-REQUISITE: |
AMTH 141 - Calculus I |
|
COURSE OBJECTIVES: |
In order to satisfactorily complete this course, students will be required to demonstrate proficiency in the solution of technical problems involving static equilibrium. The format for solution of homework and test problems is as illustrated in the attached sample homework problem. In particular, students must demonstrate proficiency in determining the magnitudes of forces and moments required to maintain static equilibrium of rigid bodies under both concentrated and distributed loads in both 2- and 3-dimensional Cartesian coordinate systems. Additionally, students must demonstrate the ability to locate centroids, centers of mass and to calculate moments of inertia for both regularly- and irregularly-shaped bodies. |
|
HOMEWORK: |
The attached course syllabus provides details of daily reading assignments and homework problems for the entire semester. Homework problems are due at the BEGINNING of the class meeting following the date on which the homework problems are assigned. HOMEWORK PROBLEMS ARE AN INTEGRAL PART OF THE COURSE. STUDENTS CANNOT REASONABLY EXPECT TO DEVELOP THE SKILLS NECESSARY FOR SUCCESS IN THIS COURSE UNLESS HOMEWORK PROBLEMS ARE COMPLETED AS SCHEDULED. IN ORDER TO ENSURE TIMELY COMPLETION OF HOMEWORK, HOMEWORK PROBLEMS WILL BE COLLECTED AT RANDOM, AND FOR THIS REASON IT IS NECESSARY TO BRING ALL OF YOUR HOMEWORK SOLUTIONS TO EACH CLASS MEETING. HOMEWORK OFFERED FOR LATE SUBMISSION WILL NOT BE ACCEPTED, AND A FAILING GRADE WILL BE ASSIGNED. |
|
STUDENT STUDY ROOM: |
Room 230A in the Administration Building is available to engineering students for group study. Research indicates that group study is particularly beneficial for students in a technical curriculum, and students are encouraged to make the greatest possible use of the group study room. |
|
DESIGN PROJECT: |
A design project will be assigned as indicated on the attached course syllabus. The project will consist of an "open-ended" engineering problem to which there is no single correct answer. Students will be assigned to teams for the purpose of completing this project. The teams will analyze the problem amd assemble a detailed written summary of the merits of their design, including a description of trade-offs, where appropriate, the decisions made and the calculations supporting those decisions. THE DESIGN PROJECT ACCOUNTS FOR 20% OF THE COURSE GRADE. GRAMMAR, SPELLING, PUNCTUATION, SENTENCE STRUCTURE AND THE COHERENCE OF THE PRESENTATION WILL BE IMPORTANT FACTORS IN THE GRADING OF THE DESIGN PROJECT. |
|
TESTS: |
Three tests will be administered during the semester. One entire class meeting (1:15) will be devoted to each of the tests. Test dates are indicated on the attached syllabus. |
|
ATTENDANCE: |
A ttendance at class is required and will be periodically recorded. Students cannot reasonably expect to master the course material without regular attendance at class. Students are responsible for all material covered in class regardless of their attendance. Students who do not regularly attend class should not expect to receive individual tutoring from Asst. Prof. May outside of class. |
|
SPECIAL CIRCUMSTANCES: |
If you have a physical or learning disability which might affect your performance in this class, please contact the Office of Disabled Student Services as soon as possible. Once an evaluation has been made, appropriate accomodations will be determined. The Office of Disabled Student Services is located in the Administration Building, room 116C (phone 641-3317). |
|
COURSE GRADING: |
Numerical grades will be assigned to all tests and to the final examination. Letter grade equivalents of numerical grades are: |
