Objective:
This course studies particle and rigid body dynamics. Topics include: kinematics and kinetics of both particles and rigid bodies, equations of motion in rectangular, normal/tangential and polar coordinate systems, rigid body translation, rotation and general plane motion, work and energy, momentum conservation, mass moment of inertia, and free, forced and damped vibrations. Engineering design is incorporated in projects and homework assignments.
Prerequisites:
ENGR 225 Mechanics I
Text:
Engineering Mechanics: Dynamics (Vol. 2), J.L. Meriam and L.G. Kraige, 4 ed., John Wiley and Sons, New York, 1998.
Note: Be sure to read the assigned articles (sections of text) prior to class.
Problem Sets:
Problem sets are due one week from their date of assignment. Late assignments will not be graded. Detailed solutions to the homework problems will be posted outside my office after the assignment has been collected. Please submit neat, legible problem sets with all pages stapled together. Feel free to work the problems in collaboration with your peers. Take advantage of my office hours to ask specific questions about the homework problems or class material. Several supplementary texts, e.g. Schaum's Outline: Engineering Mechanics, and the Mechanics Problem Solver, which contain many solved problems are available at the library. Assignments will include projects involving computation of projectiles including both air drag and lift due to rotation (Magnus effect) using Fortran 90/95. Several homework problems will require writing simple computer programs in MATLAB or Fortran 90/95.
Grading:
There will be two quizzes and two midterm exams plus the final exam. Final grades will be weighted according to:
| Assignments | 30% |
| 2 Quizzes | 20% |
| 2 Exams | 30% |
| Final Exam | 20% |
