Fundamentals of statics; composition and resolution of forces; the analysis of force systems in two and three dimensions; and centroids and moments of inertia. Prerequisites: MATH 022 or MATH 023; PHYS 031.
Dates: May 18 - July 10 2020
The basic principles and application of rigid-body mechanics to the statics of particles are studied in this course. Two-dimensional (2D) and three-dimensional (3D) forces acting on rigid bodies, moments, vector operations, equilibrium of a particle and equilibrium of a rigid body in 2D and 3D and free body diagrams are studied. Structural analysis including simple trusses, frames, cables and introduction to shear and bending-moment diagrams are included. Frictional forces, wedges, screws, and the concept of center of gravity and centroid, moment of inertia and radius of gyration are also studied. It is expected that the students will develop critical thinking skills to successfully formulate solutions for the statics problems. Upon completion of CE 001 Statics, students will be able to: 1. Define Statics as a fundamental field of rigid body mechanics concerning particles and bodies in static equilibrium. 2. Identify forces and support reactions acting on particles and rigid bodies in 2-D and 3-D systems and draw accurate free body diagrams. 3. Apply Newton’s Laws of Motion to solve for unknown forces and support reactions on particles and rigid bodies in 2-D and 3-D systems, i.e., trusses, frames and machines. 4. Determine the centroid, center of mass and center of gravity and area moment of inertia in complex shapes using composite shapes and integration. ABET outcome: #1. An ability to identify, formulate, and solve complex engineering problems by applying principles of engineering, science, and mathematics
COURSE SCHEDULE: Course Materials Release Day: Monday Each weekly module of this course begins on a Monday (8 AM) and ends on a Sunday (12 AM or midnight). The homework assignment for that week is due on Sunday night. This is our “online week”. All the quizzes are due on Thursday (12 AM or midnight) so that I can post the solutions before the homework is due. On Monday mornings, the online materials for that particular week will be available. TEXTBOOK: • Engineering Mechanics: Statics with Connect by Michael E. Plesha, Gary L.

This course uses resources in different formats. Please make sure that you can open a PDF document and watch a YouTube video. Adobe Acrobat Reader is needed to view PDF documents. If you do not have adobe reader on your computer you can download it for free from the Adobe website at http://www.adobe.com. Additionally, you will use Mc-Graw-Hill Connect to complete and submit the quizzes for this course. Connect is an online assessment tool from Mc-Graw-Hill to accompany Plesha’s Engineering Mechanics: Statics Please make sure you register for Connect as this will be a required and graded component of the course. More details of Connect registration and access to the Plesha’s e-book are posted on Bb under the Syllabus tab. ONLINE LEARNING AND COMMUNICATION: Unlike face-to-face teaching in a classroom, you will not have the opportunity to raise your hand and ask questions about the lecture. Therefore, I highly recommend taking notes, while watching the lectures. The pdfs of the lecture notes are provided to you and please print them before watching the lectures. If you have any questions, you can (I) ask in the discussion forum, (II) e-mail me, or (III) discuss during office hours. Discussion Forum: We will use the Discussion Board frequently in this course. The discussion Forum is an effective resource for dialogue. By posting materials and questions to the discussion Forum, the entire class can benefit by the information being exchanged. If one person asks a question, most likely others will have the same question. To really get the full experience of how powerful the discussion forums can be, after (or before) posting your initial comments for the module, it is expected that you respond to two of your classmates discussion posts. When replying, choose a post from a classmate that offers a different interpretation or viewpoint than yours. In responding to others, I encourage you to ask a question, build on their observation, or extend an idea. You are encouraged to attach any images, i.e. Free Body Diagrams (FBDs) or the sketches of the problems you work on. Discussion will take place on weekly basis throughout each module. By Thursday of the week, you should have participated in the discussion forum. So that by the time you complete your homework assignment, hopefully, all questions will have answered. If the Discussion Forums are new to you, please follow this link to learn more. Announcements: The first page that you see when you log into this course website is the announcements (home) page. It is important to read the announcements each time you log in for any updates, reminders or other general announcements. Each time I post an announcement, you will also receive it in an email. Netiquette Netiquette stands for Network Etiquette. It refers to proper behavior while interacting online. The golden rule of netiquette is essentially to treat people as you would want to be treated. Please be polite and considerate. Think about whether your comment could cause hurt feelings. Be careful about how your words can come across because misunderstandings can be common online. EXAM AND HOMEWORK POLICIES: Note: This course requires remote proctored exams through Proctor U. You can pick any day of the week to take your exams. Midterm exams will be prepared for one and a half hours and the final exam is for two and a half hours.
GRADING: Participation and Attendance 10% (online discussion forums and blogs via Bb) Quizzes 10% (several quizzes will be assigned each week via Connect) Homework 15% (one HW will be assigned each week) Midterm Exams 40% (two exams, each counts 20%, proctored through ProctorU) Final Exam 25% (proctored through ProctorU) ----------------------------- Total 100% The minimum passing grade is 62%.
