Course Syllabus
Course: ENGR 2140
Division: Natural Science and Math
Department: Computer Science & Engineering
Title: Mechanics of Materials
Semester Approved: Fall 2023
Five-Year Review Semester: Summer 2028
End Semester: Summer 2029
Catalog Description: ENGR 2140 Mechanics of Materials builds on the principles learned in ENGR 2010 Statics by exploring the deformation and possible failure of static objects subjected to forces and moments. Stress and strain due to axial, torsional, bending, and shearing loads are studied. The effect of differing materials on these analyses is also explored. ENGR 2140 is a prerequisite for several junior and senior level engineering courses (e.g. Machine Design, Engineering Materials, Structural Analysis, etc.). This course was previously listed as "Strength of Materials".
Semesters Offered: Fall, Spring
Credit/Time Requirement: Credit: 3; Lecture: 4; Lab: 0
Prerequisites: Calculus II (MATH 1220), and Statics (ENGR 2010)
Corequisites: N/A
Justification: This course is designed as a component of the standard preprofessional curriculum in engineering. ENGR 2140 is part of a series of courses generally falling under the category of mechanics of materials in a broader sense. As a foundational class, significant emphasis is placed on the process of problem solving and appropriate presentation of the analysis. This course is designed to be equivalent to ENGR 2140 courses taught by other engineering programs in the Utah higher education system.
Student Learning Outcomes:
Students will be able to demonstrate the ability to strategically approach course relevant engineering analysis and design problems by identifying known information, objectives, available tools and processes, and a suitable plan of action. Students will be assessed through a combination of participation, homework assignments, projects, exams, and/or quizzes.
Students will be able to analyze the stress, strain, and possible failure of an object subjected to axial, torsional, bending, and shearing loads in both metric and English engineering systems of measurement. Students will be assessed through a combination of participation, homework assignments, projects, exams, and/or quizzes.
Students will be able to utilize both the metric and English engineering systems of measurement in solving problems related to the course content. Students will be assessed through a combination of participation, homework assignments, projects, exams, and/or quizzes.
Students will be able to apply fundamental principles learned in prerequisite courses to more complex/realistic methods and systems. Students will be assessed through a combination of participation, homework assignments, projects, exams, and/or quizzes.
Content:
The course covers mechanics of materials principles in a problem-solving context for some or all of the following topics:
• Stress and strain effects of tension, compression, and shear forces
• Axially loaded members
• Torsionally loaded members
• Statically indeterminate members
• Shear forces and bending moments
• Stresses in beams and beam deflection
• In-plane and out-of-plane stress analysis
• Column Buckling
Related topics covered may include: material properties, thermal expansion, power shaft design, beam and column design, combined loadings, Mohr's Circle to find principal stresses, and pressure vessels.
The course will endeavor to explore these topics in a variety of real-world applications relevant to the multiple engineering disciplines and majors that utilize the course material. Where appropriate, alternate problem-solving approaches for a given topic will be explored to provide a greater variety of tools that may be employed based on a given situation and/or student’s preference.
Key Performance Indicators:
Grading for the class will be weighted as follows:
Homework Assignments 10 to 50%
Exams 0 to 50%
Projects 0 to 50%
Quizzes and Participation 0 to 20%
Representative Text and/or Supplies:
R. C. Hibbeler: Mechanics of Materials, Prentice-Hall.
Beer, Johnston, DeWolf, & Mazurek: Mechanics of Materials, McGraw-Hill.
Goodno & Gere: Mechanics of Materials, Cengage Learning.
Pedagogy Statement:
The course will be delivered via classroom lecture and recitation (days devoted to group problem solving and reviewing material previously covered). Additional online resources may also be provided. Students will develop understanding of course concepts through use of the assigned text, individual and/or group study (including assigned homework), and group problem solving in class. Both symbolic and value-based problem solving will be utilized. The structure of the course will consider the needs of students coming from diverse backgrounds, including varied levels of preparation for collegiate study and students with time gaps since the completion of prerequisite courses. Tools such as instructor observations and office hours, exams, and quizzes may be employed to assess progress of individual students and the class as a whole so that prudent adjustments may be made to facilitate individual and group success. It is anticipated that these practices will also facilitate learning and comprehension in students whose native language is not English. Students are presented with opportunities to share their questions and frustrations in an environment where mistakes are part of the learning process rather than a mark of inability.
