Statics GE 204

Course description

Course represents the transition from theoretical studies of forces and equilibrium, as studied in physics, to applied science. The equilibrium of a particle when acted upon by a system of forces and the equilibrium of bodies in two and three dimensions is studied. Also covers equilibrium considerations for the design of trusses and machines, effects of friction on equilibrium, and calculations of centroids and center of gravity. Prerequisites: MTH 171 and PHY 171. A minimum grade of C- is required for all prerequisites.

Homework, quiz, & exam policies

Homework & homework quiz policies

Weekly homework will be due on Sundays, but it will primarily not be turned in for credit. Each week you will turn in your work for a single homework problem. You will also have a weekly homework quiz that will open at midnight on Thursday and close at midnight on Sunday. This quiz will cover the remaining problems and will be available on moodle. You will have three tries to complete the quiz and will receive the average of your three scores. Late quizzes will receive no credit. The lowest two quiz scores will be dropped.

Working in groups on homework is strongly encouraged, but quizzes must be completed individually.

Exam policies

Calculators will be allowed. Only ones own notes and the notes provided by the instructor will be allowed. No communication-devices will be allowed.

No exam may be taken early. Makeup exams require a doctor’s note excusing the absence during the exam.

Grading policies

Total grades in the course may be curved, but individual homework quizzes and exams will not be. They will be available on moodle throughout the semester.

Academic Honesty/Professionalism

What is Academic Integrity?

Saint Martin’s University is a community of faculty, students and staff engaged in the exchange of ideas in the ongoing pursuit of academic excellence. Essential to our mission is a focused commitment to scholarly values and intellectual integrity, and a respect for the ideas, beliefs and work of others. This commitment extends to all aspects of academic performance. All members are expected to abide by ethical standards both in their conduct and their exercise of responsibility to themselves and toward other members of the community. As an expression of our shared belief in the Benedictine tradition, we support the intellectual, social, emotional, physical and spiritual nurturing of students.

What is Academic Dishonesty?

Saint Martin’s University defines academic dishonesty as violating the academic integrity of an assignment, test and/or evaluation of any coursework. This dishonest practice occurs when you seek to gain for yourself or another an academic advantage by deception or other dishonest means. You have a responsibility to understand the requirements that apply to particular assessments and to be aware of acceptable academic practice regarding the use of material prepared by others. Therefore, it is your responsibility to be familiar with the policies surrounding academic dishonesty as these may differ from other institutions.

The Acceptable Use of AI in Coursework

Any use of technology that misleads a reviewer in assessing the student’s mastery of a specific set of skills or knowledge is a type of intellectual dishonesty, that is, a type of cheating. Students who are unsure about the appropriateness of using an artificial intelligence tool (or “AI”) should check with the instructor before using it. This includes the use of tools that generate text, images, video, code, and other works. If you are permitted by your instructor to use one or more AI tools in producing your work, you should disclose the use of that tool. You should say which tool you used and how you used it. Then if you use specific AI generated content (text, images, videos, audio, code, and so on) you should cite it in the style (APA, MLA, and so on) specified by your instructor.

University-Sanctioned Activities

If you are absent from class due to university-sanctioned activities, such as sports, it is your responsibility to request that the absence be excused; otherwise, the absence will be recorded as unexcused. Absent students are responsible for catching up with the class, and if any assignments are due on the day of the absence, it is your responsibility to turn in the assignments on time.

Counseling and Wellness Center

There may be times, as a college student, when personal stressors interfere with your academic performance and your daily life. The Counseling and Wellness Center supports students by addressing mental and emotional well-being with FREE and confidential services. To schedule an appointment, call 360-412-6123 or email [email protected] or stop by the CWC (1 st floor St. Raphael Center).

If you would rather not go to the CWC or need support in the evenings and weekends, please consider using the TimelyCare app ( to speak with a mental health provider, free, 24/7, from your phone or computer.

Center for Student Success

The Center for Student Success is an integrated learning assistance program that offers services for students at all levels of achievement in pursuit of intellectual growth and academic excellence. The Center offers peer tutoring, study support, first year/early major advising, and writing support. Please investigate ways in which to support your learning. The CSS is located in the lower level of O’Grady Library. You can sign up for tutoring appointments on the webpage:

Religious Accommodation Statement

Saint Martin’s University, in honor of the sacredness of the individual, and being deeply rooted in the Catholic Benedictine tradition of higher education, values the many religious and spiritual practices of our campus community. Saint Martin’s University supports our students in their ongoing journey of becoming. In compliance with Washington State Law RCW 28B.137.010, Saint Martin’s University reasonably accommodates students for reasons of religious observances.

Access and Accommodations

Your experience in this class is important to me. If you have already established accommodations with Disability Support Services (DSS), please communicate your approved accommodations to me at your earliest convenience so we can discuss your needs in this course. If you have not yet established services through DSS, but have a temporary health condition or permanent disability that requires accommodations (conditions include but are not limited to mental health, attention- related, learning, vision, hearing, physical or health impacts), you are welcome to contact DSS at 360-438-4580 or [email protected] or [email protected]. DSS offers resources and coordinates reasonable accommodations for students with disabilities and/or temporary health conditions.  Reasonable accommodations are established through an interactive process between you, your instructor(s) and DSS.  It is the policy and practice of the Saint Martin’s University to create inclusive and accessible learning environments consistent with federal and state law.

Sexual Misconduct/Sexual Harrassment Reporting

Saint Martin’s University is committed to providing an environment free from sex discrimination, including sexual harassment and sexual violence. There are Title IX/sexual harassment posters around campus that include the contact information for confidential reporting and formal reporting. Confidential reporting is where you can talk about incidents of sexual harassment and gender-based crimes including sexual assault, stalking, and domestic/relationship violence. This confidential resource can help you without having to report your situation to the formal reporting process through the Dean of Students – Ms. Melanie Richardson, Associate VP of Human Resources – Ms. Cynthia Johnson, Public Safety – Ms. Sharon Schnebly, or the Office of the Provost – Dr. Tanya Smith-Brice, unless you request that they make a report. Please be aware that, in compliance with Title IX and under the Saint Martin’s University policies, educators must report incidents of sexual harassment and gender-based crimes including sexual assault, stalking, and domestic/relationship violence. If you disclose any of these situations in class, on papers, or to me personally, I am required to report it.
