Strengths of Materials ET-228 Syllabus

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; 2nd edition; McGraw-Hill Co.; 1997.

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

  1. Explain simple stresses, indirect stresses, and applications
  2. Explain a shear moment diagram  …Given a selected free body diagram and all associated geometry and loading of the body…
  1. Correctly calculate all the resultant internal stresses and external deformations of the body
  2. Design the material and geometric requirements of the body in accordance with a proscribed specification.
