Prerequisites: EGR 2103 Statics (requires a grade of C- or better)

Textbook(s) and /or required material: James M. Gere and Barry J. Goodno, Mechanics of Materials, 8th Edition, CENGAGE Learning, 2013.

Major Prerequisites by Topic: Differentiation, Integration, Static Equilibrium, Free-Body Diagrams.

Topics Covered: 1. Tension, compression, and shear 2. Axially loaded members 3. Torsion of bars 4. Shear and bending moment diagrams 5. Stresses in beams 6. Analysis of stresses and strains 7. Mohrs Circle for plain stress and plain strains 8. Deflection of beams 9. Statically indeterminant structures 10. Buckling of columns

Contribution of course to meet the professional component: This course prepares students to work in the areas of mechanical systems, mechanical design, mechanics and materials.

Relationship of the course to students outcomes: This course primarily contributes to the Mechanical Engineering program outcomes that develop student abilities: (a) to apply knowledge of mathematics, science, and engineering (e) to identify, formulate, and solve engineering problems

The course contributes in a secondary way to Mechanical Engineering program outcomes: (k) to use the techniques, skills, and modern engineering tools necessary for engineering practice. (l) to apply principles of engineering, basic science, and mathematics to model, analyze, design, and realize

physical systems, components or processes.

Course objectives (contribution to student outcomes): For students to demonstrate, 1. Determining of normal stresses and strains, shear stresses and strains (a, e) 2. Determining of deformation, stress and strain in axially loaded members (a, e) 3. Determining of stresses and deformation in torsion of prismatic bars (a,e) 4. Developing shear and bending moment diagrams (a, e, k) 5. Determining of stresses and strains in bending of beams (a, e)

6. Determining of principal and maximum shear stresses, principal and maximum shear strains (a, e, k, l) 7. Constructing of Mohrs Circle for plain stress and plain strains (a, e, l) 8. Determining of deflections in beams: integration of bending moment, integration of shear force, moment-

area method, and method of superposition (a, e) 9. Determining critical buckling load in columns (a, e, l)

Performance Criteria: Objectives 1 through 9 will be evaluated using evaluation results of homework assignments, quizzes, exams I, exam II, and comprehensive final examination.
