COURSE NUMBER: PHYS211
COURSE TITLE:Applied Mechanics-Dynamics
DIVISION:Sciences
IAI CODE(S): EGR 943
SEMESTER CREDIT HOURS:3
CONTACT HOURS:45
STUDENT ENGAGEMENT HOURS:135
DELIVERY MODE:In-Person

COURSE DESCRIPTION:
Applied Mechanics is primarily a course in solving problems involving dynamics. The majority of the time is spent on the theoretical analysis of the kinetics of particles and rigid bodies involving force, mass, acceleration, energy, momentum, and impulse, as well as the kinematics of a system of particles and rigid bodies. This theoretical analysis is the solid foundation for students to develop the ability to analyze engineering problems in a logical manner. Applied Mechanics is very important for students in their subsequent study in engineering disciplines and in their future practical engineering applications.

PREREQUISITES:
PHYS152 Applied Mechanics-Statics - This course includes the fundamental concepts of Newtonian mechanics to the statics of particles and rigid bodies in two dimensional and three dimensional space. It covers mathematical analysis of forces and their equilibrium in structural members and forces due to friction; calculation at center of gravity, center of pressure, and moment of inertia; study of virtual work principle for a particle and for a rigid body. MATH130 Calculus & Analytic Geometry II - The second course in calculus and analytic geometry. Techniques of integration and differentiation of exponential, logarithmic, trigonometric, and hyperbolic functions; limit of indeterminate forms; polar coordinates; parametric equations; conic sections; infinite series.

NOTES: This course involves a great deal of work on the student's part and would be nearly impossible for the student to master the content without persistently working the problems. As prerequisite, students are expected to possess the knowledge of general physics and calculus. Students are expected to spend an additional 3-5 hours per week outside of class to complete all assignments. To achieve the general education goals and learning outcomes, students will communicate meaningfully in writing while presenting information. Students will translate quantifiable problems into mathematical terms and solve these problems using mathematical operations. Students will construct graphs and charts, interpret them, and draw appropriate conclusions. Course activities include:
  1. Speaking Assignments: students will present research individually or in groups using current technology to support the presentation; students will participate in discussions and debates related to the topics in the lessons
  2. Case Studies: complex situations and scenarios will be analyzed in cooperative group settings or as homework assignments
  3. Lectures: this format will include question and answer sessions to provide interactivity between students and the instructor
  4. Videos or Invited Speakers: related topics will provide impetus for discussion

EVALUATION:

The student will be evaluated on the degree to which student learning outcomes are achieved. A variety of methods may be used, such as tests, quizzes, class attendance and participation, reading assignments, projects, homework, presentations, and final exam. Students are expected to completely solve problems as homework from each section as assigned. Homework grade will be assigned based on the solution procedure, results, organization, and presentation. Each solution shall be explained with all the detail and diagrams necessary for another person to review. Hourly exam is composed by solving problems selected from each chapter. A comprehensive final exam is given at the end of the semester.

Three major separate sources will contribute to the grade in this course:
final exam
hourly exams (including quizzes and projects)
homework (including presentation)
30%
50%
20%

Determination of grade is according to the following scale:
100-90%
89-80%
79-70%
69-60%
59-00%
