COURSE NUMBER: PHYS152
COURSE TITLE:Applied Mechanics-Statics
DIVISION:Sciences
IAI CODE(S): EGR 942
SEMESTER CREDIT HOURS:3
CONTACT HOURS:45
STUDENT ENGAGEMENT HOURS:135
DELIVERY MODE:In-Person

COURSE DESCRIPTION:
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, centers of pressure, and moments of inertia; study of virtual work for systems. The free-body diagram approach and vector analysis methods are used.

PREREQUISITES:
PHYS106. Physics-Mechanics is a calculus based physics, which introduce for engineering, physics, mathematics, and chemistry students to kinematics, forces, energy, and circular motion. The class consists of lecture, demonstrations, and laboratory. Class meets for 3 hours of lecture per week. IAI code PHY 911.

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


STUDENT LEARNING OUTCOMES:
Course Goals:
Students are expected to apply strong critical thinking skills in terms of problem solving. Students are expected to be able to determine from any initial question of any of the following that apply:
  1. The meaning and importance of all given information
  2. the primary unknown for which a solution is desired
  3. any secondary unknowns or relationships that may be required
  4. properly use the techniques required to move toward solution
  5. properly explain the meaning of the solution

TOPICAL OUTLINE:
Applied mechanics (PHYS152) is primarily a course in solving problems involving statics. Using Physics 106 as a background, it elaborates on the type of problems encountered there. Although the theoretical reasoning behind the physical principles is covered, the main emphasis is on the application of the theory to problems of practical applications. The main objective of the course is to develop the ability to analyze an engineering problem in a simple and logical manner and to apply its solution to the fundamental principles of mechanics. In a 16-week-long semester, the following topics are covered:
  • Introduction to statics(0.5 weeks):
    • Newton's laws of motion and gravitational attraction
    • units of basic quantities
  • Vectors-forces and moments. (2.5 weeks)
  • Equilibrium of Particles. (1.5 weeks)
  • Equilibrium of Rigid Bodies (2.5 weeks)
  • Equivalent force/moment systems (1.5 weeks)
  • Internal forces in beams, structure-trusses, frames, and machines (2.5 weeks)
  • Distributed forces (1.0 week)
  • Centroids and centers of gravity (1.0 week)
  • Friction (1.0 week)
  • Method of virtual work (1.0 week)
  • Moments of inertia (1.0 week)

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%
