**Strength of Materials Syllabus ET-228**

**Course Description:** An introductory study of the effects due to forces acting on deformable bodies; including tension, compression, shear, torsion, bending, combined stresses, and the design of members subjected to such stresses.

**Prerequisite:** ET-224

**Text: **Fa-Hwa Cheng; Statics and Strength of Materials; 2^{nd} edition; McGraw-Hill Co.; 1997.

**Learning Outcomes:** As a result of instruction in this course, students will be able to:

- Explain simple stresses, indirect stresses, and applications
- Explain a shear moment diagram …Given a selected free body diagram and all associated geometry and loading of the body…

- Correctly calculate all the resultant internal stresses and external deformations of the body
- Design the material and geometric requirements of the body in accordance with a proscribed specification.
