Course Description (3.5 Credits)
This course explores the definitions and concepts of forces and moments, and their applicability to
the analysis of static, rigid mechanical systems. Specific topics include free body diagrams,
resultants and equivalent force systems, static equilibrium, shear and bending diagrams, static
analysis of trusses and frames, friction forces, and calculation of centroids and area moments of
inertia.
Course Textbook Information

2009
Course Objectives
The objective of this course is to introduce students to engineering mechanics and to develop
problem-solving capabilities using the principles of statics.
Course Outcomes (measurements in parentheses)
The student will be able to:
1. perform force and moment vector operations such as addition, subtraction, dot product,
and cross product (Homework, Exams, Program #1, Final Exam);
2. draw free body diagrams of both complete and sectioned bodies (Homework, Exams, Final

Exam);
reduce a system of distributed forces to an equivalent system (Homework, Exams, Final
Exam);
perform equilibrium analysis (2D and 3D) on particles, rigid bodies, and sectioned bodies
(Homework, Exams, Program #2, Program #3, Final Exam);
include frictional forces in the static analysis of mechanical systems (HW #9, Final
Exam);
compute centroids and area moments of inertia (Homework, Final Exam);
implement static equilibrium analysis procedures in computer code (Program #1 - #3).
General Education Competencies

Thinking.
Disabled Applicants and Students
Daniel Webster College is committed to compliance with Section 504 of the Rehabilitation Act of
1973 and its regulations. The school does not discriminate on the basis of disability in
admission or access to, or treatment or employment in, its programs and activities. The
school's student disability coordinator coordinates Section 504 compliance. Applicants or
students with a disability may request an accommodation by contacting Kathy Hipp, Associate
Dean of Arts and Sciences, at 603-577-6659 or hipp@dwc.edu; or by contacting the Office of
Academic Affairs: https://studentportal.dwc.edu/Pages/HelpCenter.aspx
Academic Honesty
Intellectual curiosity is at the heart of the academic enterprise. Students, faculty and
administration at Daniel Webster College consider such violations as cheating and plagiarism to
be so unethical as to call into question whether the violator should continue as a member of the
College community. Transcripts that misrepresent academic performance not only endanger
students’ chances for success in their careers but also damage the integrity and reputation of
the institution.
Student Honor Pledge
Daniel Webster College believes that all students have the right to learn in an academic
community that insures fair competition, and respects truth and honesty. Academic dishonesty
is not tolerated at Daniel Webster College. The Student Honor Pledge is intended to create a
community of fairness, respect and responsibility in the pursuit of academic enterprise. All
students are expected to abide by the Student Honor Pledge.
I pledge on my honor, as a student at Daniel Webster College, that I have neither given
nor received any unauthorized aid on this assignment/examination.
For more information regarding Daniel Webster College’s ethical standards, please refer to the
current college catalog.
Grading Scale
The following scale is based on the grading structure outlined in the Daniel Webster College
catalog and is used to assign letter grades:
A = 93+
C+= 76-79
A- = 90-92
C = 70-75
B+= 87-89
D = 65-69
B = 83-86
F = Below 65
B- = 80-82

Expectations
Homework problems from the text will be assigned on a regular basis and are subject to
change. A limited number of other assignments not in the text might be given as supplemental
exercises. It is expected that the interested student will endeavor to solve these problems.
Remember that you cannot adequately learn this material without practicing the
methods. Talk to me in advance if you have reasonable reason(s) for not being able to turn in
your homework or any assignment on time. To be fair to all students, late homework or other
assignments are given a 33% reduction in points per day that the homework / assignment is
late. A “day” is defined as 24 hours, beginning at the start of class time.
In addition, there will be a series of three (3) analysis and programming projects
assigned which will utilize commercial software. In support of the student evaluation process,
there will be two (2) exams, and one (1) comprehensive final exam. No make-ups for
exams will be given unless satisfactory advanced notice and reason is supplied to the
instructor. The grades will not be curved. The grades will be assigned based on the absolute
grade scale shown above.
Active class participation is expected. In this course you will be expected to act in a
professional manner. Among other things, this includes showing up on time prepared for the
task at hand. This shall include not just being on time for class, but also for any and all
additional outside meetings you will have with group work. You will be expected to read
assigned chapters/tutorials before coming to class and be ready to actively participate.
Classroom activities such as chatting, use of computer, ipod, cell phone and other electronics
are not allowed. In addition, eating in class is not allowed.
Students may ask questions of one another when working on out-of-class assignments.
However, each student/team must do their own work. A first occurrence of academic
dishonesty will result in a zero for that assignment for all who are involved. A second
occurrence will result in an F for the course. Note that all such occurrences must be reported in
writing to the Chief Academic Officer who may prescribe additional penalties.
