In par-ticular, the should be familiar with the basic equations of motion, necessary for their subsequentstudy of flight mechanics and attitude dynamics.IMPACT ON SUBSEQUENT COURSES IN CURRICULUM: The knowledge and abil-ities taught in this course are an essential prerequisite for subsequent courses involving dynamics;in particular, ASE365, 366K, 367K, 167M, and 370L.RELATION OF COURSE TO PROGRAM OUTCOMES:: This course contributes to thefollowing ABET Criterion 3 outcomes and those specific to the EAC accredited program.Outcome Outcomea. An ability to apply knowledge of mathematics, science, g. An ability to communicate effectivelyand engineering xb. An ability to design and conduct experiments, as well as to h. The broad education necessary to understand the impact ofanalyze and interpret data engineering solutions in a global/societal contextc. An ability to design a system, component, or process to i. A recognition of the need for and an ability in life-meet desired needs x long learningd. An ability to function on multi-disciplinary teams j. A knowledge of contemporary issuese. An ability to identify, formulate, and solve engineering k. An ability to use the techniques, skills, and modernproblems x engineering tools necessary for engineering practice xf.

Energy Methods (6) (a,e,k,E,G)4. Momentum Methods (4) (a,e,k,E,G,L)5. Rigid-Body Kinematics (6) (a,e,k,E,I)6. Two-Dimensional Rigid Body Dynamics (3) (a,c,e,k,E,I)7. Energy and Momentum Methods in Rigid Body Dynamics (3) (a,e,k,E,I)8. Three Dimensional Rigid Body Dynamics (6) (a,c,e,k,E,I)9. Vibrations (3) (a,E,I)PROFESSIONALISM TOPICS:The course helps to develop written and oral communication skills and enforces team work.DESIGN ASSIGNMENTS: There are no explicit design projects. However, there will be in-class discussions of how the material presented in class influences engineering hardware design.In some assignments, students will be asked how their answers would influence the design of aparticular design or system. Overall, it is estimated that about 0.2 semester credit hours aredevoted to the general area of ”design”.LABORATORY ASSIGNMENTS: There are no laboratory assignments.COMPUTER: No specific software has been assigned for the homework assignments in this class.At this stage, an understanding of the fundamental aspects of particle and rigid body dynamics,can probably best be obtained through relatively simple problems which have analytic soulutions.Solution of a few problems assigned for homework may be facilitated using a computer, and studentsare free to use whatever software they wish.TEXT: A. Bedford and W. Fowler, Engineering Mechanics: Dynamics, fifth edition, Prentice Hall,Upper Saddle River, New Jersey 07458, 2008.CLASS FORMAT: This is a lecture class and meets 3 times a week. The lectures are comple-mented with mandatory exercise (help) sessions once a week (two hours).3EM 311M Course Syllabus Fall SemesterUnique No. 14075, 14080, 14085, 14115 09CLASS OUTLINE SCHEDULE:Date Topic Reading Problems solved Anticipatedin class homework problemsWed, Aug 26 Kinematics of a point: position, 12,1-5 13.5,14,27,48 13.6,15,28,49Fri, Aug 28 velocity, acceleration 13.1-2Mon, Aug 31 Cartesian coordinates 13.1-33 13.60,80,89,141 13.61,81,90,142Wed, Sep 2 Cylindrical coordinatesFri, Sep 4Wed, Sep 9 Frenet coordinates 13.1-3 13.150,157,117,133 13.151,158,116,131Fri, Sep 11 Curvilinear motion -cont. 13.134,129 13.135,130Mon, Sep 14 Kinetics of a point: equations of 14.1-6 14.15,21,38,55 14.16,22,36,56Wed, Sep 16 motion in Cartesian, cylindrical, 14.75,83,105,107 14.76,93,106,108,115Fri, Sep 18 and Frenet cordinatesMon, Sep 21 Principle of work and energy, 15.1-6 15.12,19,24,70 15.13,14,20,26,63Wed, Sep 23 conservative forces 15.87,93,114 15.88,92,115Fri, Sep 25Mon, Sep 28 Principle of impulse and momen- 16.1-5 16.10,29,43,60 16.11,30,45,61Wed, Sep 30 tum, impact, principle of angular 16.79,91,95 16.80,92,93Fri, Oct 2 impulse and momentumMon, Oct 5 Kinematics of rigid bodies: 17.1-6 17.6,15,32,58 17.7,34,37,59Wed, Oct 7 angular velocity and acceleration 17.70,71 17.72,75Fri, Oct 9 vectorsMon, Oct 12 Moving reference frames 17.1-6 17.85,91,103,121 17.86,92,104,122Wed, Oct 14 17.126,145,149
