COURSE DESCRIPTION: This course provides an introduction to statics, the branch of mechanics that is concerned with the analysis of loads (force and torque, or "moment") on physical systems in static equilibrium, that is, in a state where the relative positions of subsystems do not vary over time, or where components and structures are at a constant velocity. When in static equilibrium, the system is either at rest, or its center of mass moves at constant velocity. Course content includes vector algebra, forces, couples, moments, resultants of force couple systems; friction, equilibrium analysis of particles and finite bodies, centroids; and applications.

SUMMARY OF COURSE CONTENT: Vectors, forces, moments and equilibrium in two and three dimensions.  Structures, centroids and centers of mass, moments of inertia, friction.  Internal forces and moments.

LEARNING OUTCOMES: Upon successful completion of this course, the student will be able to: - represent forces and moments as vectors in two and three dimensions; - apply equilibrium principles to analyze forces acting on a point or body in two and three dimensions; - analyze trusses, frames and simple friction problems under equilibrium conditions; - determine the centroid, center of mass, and moment of inertia for simple and composite cross-sections; - analyze internal axial and shear forces and bending moment in a loaded beam.

GRADING POLICY -ASSESSMENT METHODS: Assignment Guidelines Weight Homework Online Homework will be assigned, completed, submitted and graded using Mastering Engineering. Each week's homework assignment is due on Thursday at the start of class. No credit will be given for late assignments. 15% In-class Exams Five in-class exams will be given, as indicated in the course schedule. The average exam score will count for 60% of the grade. 60% Comprehensive Final Exam Students whose in-class exam average is an A or A- shall be exempt from the final exam. Otherwise, the comprehensive final exam will count for 25% of the grade. 25% -ASSESSMENT CRITERIA: AA: 94-100% A-: 90-92% BB+: 87-89% B: 83-86% B-: 80-82% CC+: 77-79% C: 73-76% C-: 70-72% DD+: 67-69% D: 63-66% D-: 60-62% FAverage is less than 60%. -ATTENDANCE REQUIREMENTS: ATTENDANCE REQUIREMENTS AND EXAMINATION POLICY Attendance will not be taken, except on exam dates.  The penalty for a missed exam is a zero grade.  Students that miss even a single day of lecture are likely to fall behind in the course material.  Each concept introduced in the course builds on mastery of previous concepts.  The best strategy for success in this course is to participate in class and to stay current with all homework assignments. You cannot make-up a major exam (midterm or final) without the permission of the Dean’s Office. The Dean’s Office will grant such permission only when the absence was caused by a serious impediment, such as a documented illness, hospitalization or death in the immediate family (in which you must attend the funeral) or other situations of similar gravity. Absences due to other meaningful conflicts, such as job interviews, family celebrations, travel difficulties, student misunderstandings or personal convenience, will not be excused. Students who will be absent from a major exam must notify the Dean’s Office prior to that exam. Absences from class due to the observance of a religious holiday will normally be excused. Individual students who will have to miss class to observe a religious holiday should notify the instructor by the end of the Add/Drop period to make prior arrangements for making up any work that will be missed. The final exam period runs until ____________

ACADEMIC HONESTY As stated in the university catalog, any student who commits an act of academic dishonesty will receive a failing grade on the work in which the dishonesty occurred. In addition, acts of academic dishonesty, irrespective of the weight of the assignment, may result in the student receiving a failing grade in the course. Instances of academic dishonesty will be reported to the Dean of Academic Affairs. A student who is reported twice for academic dishonesty is subject to summary dismissal from the University. In such a case, the Academic Council will then make a recommendation to the President, who will make the final decision.

STUDENTS WITH LEARNING OR OTHER DISABILITIES John Cabot University does not discriminate on the basis of disability or handicap. Students with approved accommodations must inform their professors at the beginning of the term. Please see the website for the complete policy.
