MAE 2104 - Engineering Mechanics II - Fall, 2011 MW 4:30-5:45 S-ENG B-215 Instructor: Robert G. Gist Office and Hours: SENG A-418, (Mon 11a-12:30, Tue 1-2, Wed 6-7) UCCS e-mail: rgist@uccs.edu Web Site: http://www.uccs.edu/~rgist Text: Engineering Mechanics: Statics & Dynamics, 12th ed., by Hibbeler ISBN: 9780138149291 (or dynamics-only version ISBN: 9780136077916) Course Description: (This is the second semester of a two-semester course covering engineering statics and dynamics.) Dynamics of a particle. Kinetics of a system of particles. Kinematics of rigid bodies in two and three dimensions. Free and forced vibrations with and without viscous damping. Credit Hours: 3 Prerequisite: MAE 2103 (Eng. Mech. I) Co requisite: Math 340 (Intro to Diff. Eq.) Attendance: Attendance will not be monitored. It is each student’s responsibility to cover any material due to missed lectures. Call the Snow Line (255-3346) for school closures. Arrangements should be made in advance for absence due to religious or spiritual observances. Homework: Homework will be due at the start of class. You will typically have at least one week after homework is assigned. Study groups are acceptable and encouraged, but homework should be based on individual effort and work and intermediate calculations must be shown. Homework turned in after it is due is subject to a 10% penalty per late class period. Each homework set will consist of around 5-7 problems from the chapter. Each problem will be assessed on a scale of 0 to 5, with partial credit given for correct procedures and deductions taken for errors, missing units or improper format. Format for Homework: 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: Dates for exams are tentative, and may occur a week before or after the date indicated below. At least a week’s notice will be given before the exam. There will be no scheduled make-up exams. Excuses for illness or family emergencies must be communicated to the instructor prior to the missed exam if possible. Exams are closed book, but calculators and a 3”x5” cue card will be allowed. Exam 3 will be administered on the day of finals, and is not cumulative. Grades: In summary, your grade will be weighted as shown. The letter Homework 15% grade ranges are posted on my website. Ranges include +’s and –‘s. Exams (3) 85% Disabilities: Students with disabilities should provide their letters of certification and accommodation within the first two weeks of class. Special accommodations for tests are required a week prior to the scheduled exam date. 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, but are no substitution for engineering common sense. 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. Calculators with the ability to manipulate vectors (addition, dot and cross products) are strongly recommended. R.
