MAE 2101 Engineering Statics - Fall, 2005 MW 4:30p-5:45p ENG #103 Instructor: Robert G. Gist Office and Hours: ENG 244, Mon & Tue 12:30pm - 1:30pm, or by appointment Cell Phone: 719-321-7985 UCCS e-mail: [email protected] Web Address: http://www.uccs.edu/~rgist Prerequisites: Math 135 (Calculus I) and PES 111 (General Physics I) Text: Engineering Mechanics: Statics & Dynamics, 10th Ed., by R. C. Hibbeler http://wps.prenhall.com/esm_hibbeler_engmech_10/1,8157,952419,.html Homework: Homework is an important part of cementing the information from the lectures into practical application that will fulfill the objectives of this course. Homework will count as 30% of the course grade, and should be based on INDIVIDUAL EFFORT. It will be due at the start of the class. To be graded, homework must be neat, readable and must SHOW YOUR WORK in arriving at the answers with intermediate calculations. Partial credit will be given for problems executed correctly but with computation errors. Homework is due at the start of class. Homework turned in after class starts but prior to the end of class is subject to a 10% late penalty. Late homework turned in by the next class period after the due date will still be accepted, but will be subject to a 30% late penalty. After this time, NO LATE HOMEWORK will be accepted. If extreme circumstances should present themselves, consult with me as soon as possible. Each homework set will consist of around 5-7 problems from the chapter. Some additional problems may be offered for extra credit. Each problem will be assessed according to the following criteria: Correct procedures and equations, correct answers Correct equations identified; a few math errors Several math errors and/or incorrect equations Mostly incorrect equations or method of solution Attempted (some work beyond just writing answer) Did not attempt 5 pts 4 pts 3 pts 2 pts 1 pt 0 pts Organization: Engineering work should be clear and easy to follow. Homework should be arranged in numerical order, with pages numbered and name included on each page (or stapled together). Homework and exam solutions should be organized, and answers should be clearly marked (circled, boxed, or underlined, for example.) It is recommended that each problem contain: (a) a brief problem statement, (b) diagrams, (c) given values, (d) values to be found, (e) equations used, (f) solution steps, and (g) answer(s) with units. Exams: There will be two mid-term exams given during the semester. I will give you at least a week’s notice as to the exact date of the exam as well as the material you will be responsible for on each test. In addition to the two in-class exams there will be a comprehensive final exam on Wednesday, Dec 15. The exams will count together for 50% of your grade. The lowest score of the three exams will be dropped. Unless arrangements have been made PRIOR to any exam, THERE WILL BE NO MAKE-UP EXAMS. MISSED EXAMS WILL RECEIVE A SCORE OF ZERO. For each exam, you will be allowed to bring a 3x5 inch index card with formulas and constants written on it. Calculators are also allowed to be used for the exams (no computers). R. Gist http://www.uccs.edu/~rgist MAE 2101 Engineering Statics - Fall, 2005 MW 4:30p-5:45p ENG #103 Grades: Your grade will be based on the following weighting: Homework Project Exams (3) 30% 20% 50% Since the final exam is comprehensive, I will drop the lowest of the exam scores. I will also drop the lowest homework grade, as well. The grading criteria and ranges are posted on my website. The ranges are: 4.0 (89.5 to 100), 3.x (79.5 to 89.4), 2.x (69.5 to 79.4), 1.x (59.5-69.4) and 0.x (0 to 59.4). Ranges include +’s and –‘s. Students with disabilities should provide their letters of certification and accommodation within the first two weeks of class. Special accommodations for tests are required one week prior to the scheduled exam date. Units: Keeping track and showing units (where they exist) is a critical aspect of computing and reporting engineering results. Reminders will appear on homework problems with missing units prior to the first exam. After that (including all exams) DEDUCTIONS WILL BE TAKEN FOR MISSING UNITS. Calculators: Calculators and computers are a part of the modern engineer’s tool set. They provide an alternate means to check your answers and to reduce computation errors. If you can program and apply calculators to assist you in your problem solving, you are increasing your skill set. Calculators will be allowed during exams; HOWEVER, enough INTERMEDIATE STEPS MUST BE SHOWN to convince me that you understand how to solve the problem. Computers, PDAs, and cell phones may not be used during exams.
