MAE 2103 Engineering Mechanics I - Summer 2012 TueThu 8:00am-10:40am OCSE B-215 Course Syllabus Instructor: Robert G. Gist Office & Hours: OCSE A-418, (MonWed Noon-1:00, TueThu Noon-12:30) UCCS e-mail: rgist@uccs.edu Web Site: http://www.uccs.edu/~rgist Credit Hours: 3 Prerequisite: Math 1350 and PES 1110 Text: Engineering Mechanics: Statics & Dynamics, 12th ed., by Hibbeler ISBN: 978-0136077909 or 978-0138149291 Course Description: (This is the first semester of a two-semester course covering engineering statics and dynamics.) Force vectors, moments of force, equilibrium of a particle and rigid bodies, structural analysis and trusses, internal forces and sheer, friction, center of gravity and mass, moments of inertia, virtual work, and kinematics of particles. Attendance: Attendance will not be monitored. It is each student’s responsibility to cover any material due to missed lectures. Call 255-3346 for school closures. 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. Equations used and intermediate calculations must be shown. Homework turned in after it is due is subject to a 10% penalty per late class period. 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. 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 stapled, numbered, and your name included on each page. 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. If readability becomes a problem, feedback will be provided before any deductions are made. Project: One of the at-home activities will be the design and testing of a bridge truss. This project lets students analyze internal forces in a truss using a provided software program. Participation is awarded at least 70%, with better performance receiving a better grade. Details will be provided at a later date in class and on the website. Due date is July 26th. Exams: Dates for exams are tentative, but at least a week’s notice will be given before the exam. There will be no make-up exams. Exams are closed book, but calculators and a 3”x5” cue card will be allowed. Exam 3 will be administered on the day of Homework 15% finals, and is not cumulative. Grades: In summary, your grade will be weighted as shown. Bridge project 10% The letter grade ranges are posted on my website. Ranges Exams (3) 75% include +’s and –‘s. 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 will be allowed during exams. No particular calculator is required, but suggested calculators that operate on vectors are the TI-89 and the HP-49 or HP-50. Cell phones, classroom etiquette: Please show proper etiquette by turning cell phones to silent mode and keeping conversation to a minimum during lecture. Please remain in the classroom unless an emergency arises, since foot traffic in the class can be disruptive to other students. R.
