Course Objectives

ENGINEERING 141 – ENGINEERING FUNDAMENTALS I: is an introduction to mechanics. This course deals with the concept of equilibrium as applied to rigid bodies‐ the case in which the forces and moments acting on a body do not result in an acceleration of the body. The course will define a methodology, the method of statics, used to determine certain forces and moments acting on and within rigid bodies, and structures and machines composed of rigid components, that are in equilibrium. The most important concept that will be introduced is the free‐body diagram. The objective of this course is to instill the abilities to create and interpret free body diagrams and solve complicated mechanics problems in a clear and concise manner.

Main Entry: en∙gi∙neer Pronunciation: "en‐ju‐'nir Etymology: alter. of earlier enginer, from Middle English, alteration of enginour, from Middle French engigneur, from Old French engignier to contrive, from engin

  1. a member of a military group devoted to engineering work.
  2. (obsolete) : a crafty schemer : plotter.
  3. (a) :a designer or builder of engines (b) : a person who is trained in or follows as a profession a branch of engineering (c) : a person who carries through an enterprise by skillful or artful contrivance.
  4. a person who runs or supervises an engine or an apparatus.

To ensure students are fluent in the method of statics, both physical systems of units, International System (SI) and US Customary (FPS), are considered throughout the course problem sets. To define and communicate three dimensional vector quantities, Cartesian notation is applied throughout the course. The lectures will closely adhere to Hibbeler’s textbook sections. We begin with the study of vector algebra and rigid body equilibrium and then carry these principles forward to the basic study of structures ‐ assemblies of rigid bodies. The second half of the course starts by looking at ways of determining the internal loads in a structure or simple machine. In particular, a concise method of obtaining the internal shear and bending moment diagrams for beams is discussed thoroughly. Rounding out this course are studies of equilibrium problems involving friction and methods for locating centroids of lines, area and volumes.

Learning Outcomes

At the end of this course, students will be able to:

  1. Sketch three-dimensional Cartesian reference frames, force vectors and moment vectors.
  2. Assign reference points and calculate the moment of a force relative to those points.
  3. Combine several forces and moments to form simpler equivalent force-couple systems.
  4. Identify the forces and moments acting on a rigid body and draw the corresponding free body diagram (FBD).
  5. Apply the method of statics to FBDs to solve for reaction forces and moments, including:
    • Divide a structure into sub-assemblies that can be analyzed using equations of static equlibrium.
    • Manipulate algebraic equations of equilibrium to solve for unknown forces and moments.
    • Judge whether the static equilibrium assumption is possible based on solutions to equilibrium equations.
  6. Calculate internal forces and moments in truss and beam structures.
  7. Recognize statically determinant and indeterminant mechanics problems by observation of FBDs.
  8. Interpret parametric solutions to equilibrium equations to measure the ability of a structure or a machine to sustain loads.
  9. Organize multiple FBDs in the solution of impeding motion problems.
  10. Locate the centroids of lines, areas and volumes using single variable calculus and first moments of area.

Attendance

Students are expected to attend all classes in which they are enrolled. An academic unit may require a student to withdraw from a course if the student is registered in another course that occurs at the same time...

An Instructor may refuse a student admission to a lecture, laboratory, online course discussion or learning activity, tutorial or other learning activity set out in the course outline because of lateness, misconduct, inattention or failure to meet the responsibilities of the course set out in the course outline. Students who neglect their academic work may be assigned a final grade of N or debarred from final examinations.

Students who do not attend classes must not assume that they have been dropped from the course by an academic unit or an instructor. Courses that are not formally dropped will be given a failing grade, students may be required to withdraw and will be required to pay the tution fee for the course. https://web.uvic.ca/calenda2019-09/undergra/info/regulations/attendance.html

Academic Integrity

Academic integrity is intellectual honesty and responsibility for academic work that you submit individual or group work. It involves commitment to the values of honesty, trust, and responsibility. It is expected that students will respect these ethical values in all activities related to learning, teaching, research, and service. Therefore, plagiarism and other acts against academic integrity are serious academic offences.

The responsibility of the institution Instructors and academic units have the responsibility to ensure that standards of academic honesty are met. By doing so, the institution recognizes students for their hard work and assures them that other students do not have an unfair advantage through cheating on essays, exams, and projects.

The responsibility of the student Plagiarism sometimes occurs due to a misunderstanding regarding the rules of academic integrity, but it is the responsibility of the student to know them. If you are unsure about the standards for citations or for referencing your sources, ask your instructor. Depending on the severity of the case, penalties include a warning, a failing grade, a record on the student's transcript, or a suspension.

It is your responsibility to understand the University's policy on academic integrity: http://web.uvic.ca/calendar/undergrad/info/regulations/academic-integrity.html
