1 M. N.AZESE ENGR2302 (3:3:1) ENGR MEC II DYNAMICS MATHEMATICS DEPARTMENT Division of Arts and Sciences South Plains College SPRING 2012 Martin AZESE2 M. N.AZESE SOUTH PLAINS COLLEGE MATHEMATICS DEPARTMENT COURSE POLICIES AND PROCEDURES ENGR-2302 ENGR MEC II-DYNAMICS PURPOSE OF COURSE: This course is the first in the dynamics sequence of three courses: ENGR-2302 Dynamics, Systems & Vibrations, and Control of Dynamic Systems. The course is designed to: 1. Reinforce the isolation of free body diagrams and apply the vector forms of the laws of elementary mechanics as well as stressing the differential equation nature of dynamical models. 2. Reinforce the application of the conservation equations of mechanics to the analysis of motion. 3. Provide an introduction to simulation based design analysis, and 4. Provide pointed preparation for the Fundamentals Exam, dynamics questions. INSTRUCTOR: Mr. Martin AZESE OFFICE: 318-B PHONE: 894-9611 ext 4707 Email: [email protected] OFFICE HOURS: T-TH: 3P – 3:30P, FR: On appointment TEXTBOOK: Engineering Mechanics: Dynamics, 12/E, by Hibbeler. SUPPLIES: You will need a scientific calculator, pencils, graph paper and one notebook. The notebook will be used for class notes. ATTENDANCE: You are expected to attend class and seek help when needed. If a student sleeps in class, he may be counted absent at the discretion of the instructor. If you are absent four times throughout the semester you may be dropped with either an X or F as determined by your instructor. HOMEWORK (HW): HW is assigned in class and the exercises will be found on the MySPC webpage for this course and is due on the date mentioned. YOU are responsible for keeping up to date and prepared. Late HW will not be accepted. You can scan and email me your HW if you will not be physically present on the due date. Exercises on the HW will be from Engineering Mechanics: Dynamics, 12/E, by Hibbeler, Other Dynamics text books and Self constructed.3 M. N.AZESE LAB SESSIONS: Lab time is part of class. There may be a daily lab activity/quiz. Lab assignments are designed to reinforce the lecture and are part of the HW score. Some of the lab assignments will be graded. If a student misses a lab, he will receive a zero and the lab exercise may not be made up. TUTORING: NO TUTORING AVAILABLE FOR THIS COURSE. HOWEVER STUDENTS CAN USE MY OFFICE HOURS FOR TUTORING WITH Mr. AZESE EXAMINATIONS: There will be 4 major exams. Tentative dates for the exams will be on the schedule attached to this syllabus. Correct the exams as they are returned in partial preparation for the final examination. Exams WILL NOT be made up. If you are absent on the day an exam is given, you will receive a grade of ZERO for that exam. GRADING Homework 40% Grading Scale: A 90-100 Unit Exams 40% B 80-89 Final Exam 20% C 70-79 D 60-69 F 59 or below STUDENT RESPONSIBILITIES: 1. READ YOUR SYLLABUS! 2. Attend class and be aware of announcements made in class. 3. Read the sections assigned before class. 4. Do homework problems early enough to seek help if needed. 5. Work online assignments 6. Work extra problems, as required, to understand each topic. 7. Turn cell phones OFF (Not Silent Mode) prior to entering the classroom. Behavior and Discipline: Students are expected to treat themselves and others with respect during class time. Any student not doing so will be asked to leave. Students are expected to assist in maintaining a classroom environment that is conducive to learning. Turn off all cell phones and pagers before entering the room and refrain from reading newspapers, chewing tobacco products, or otherwise being disruptive in class. Keep cell phones OFF and out of sight. Do not take your cell phone out to clean it or for any other reason. A violation of cell phone rules is considered disruptive behavior. You may be dropped from the class for any disruptive behavior. COURSE OBJECTIVES: Drawing/isolating free-body diagrams. Writing position vectors, differentiating to obtain velocity and acceleration vectors. The six step process for formulating solutions to dynamics problems. Newton's law for a particle or point mass, linear momentum. Developing equations of motion and integrating simple differential equations of motion. The relationship between constraints and degrees of freedom, constraints in rope/pulley systems.4 M. N.AZESE Coulomb, viscous, and air drag friction. Impulse of forces, impacts between smooth spheres, coefficient of restitution, conservation of linear momentum. Computer simulation as an analysis aid, matching simulations with experimental data. Kinematic analysis of mechanisms and machines, angular velocity, and differentiation of vectors in multiple reference frames. Vector loop constraint equations. Newton's law: linear momentum rate equations for systems of particles and rigid bodies. Center of mass of a system or a rigid body. Rigid body rotational equation, angular momentum torques and moments of forces. Mass moments of inertia, radius of gyration, and parallel axis theorem. Developing equations of motion for general planar motion or rigid bodies. Contact constraints in rigid body systems, the instantaneous axis of rotation.
