ENGR 2140 Mechanics of Materials

Course 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".

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

1. 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.
2. 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.
3. Students will be able to utilize both the metric and English engineering systems of measurement in solving problems related to the course content.
4. Students will be able to apply fundamental principles learned in prerequisite courses to more complex/realistic methods and systems.

Course 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.
