MECH 208 - Strength of Materials

3 Credits: (3 lecture)

Course Description
This course continues the process of engineering analysis as developed in Mechanics 1, shifting from the external reactions to the resulting internal stresses and strains in an object. Topics include straight line tension and compression stress, shear stress and strain, properties of materials, torsional stress in circular sections, shear and moment diagrams, stresses in beams, design of beams, and deflection of beams. These subjects enable the student to design simple force carrying members. Problem solving is emphasized. Computer applications with beam analysis programs used in industry are taught and integrated into this course.  

Note Fall semester only.

Prerequisite MECH 202.

A. Develop an understanding of the basic principles of material strengths that are a limiting condition of design.

B. Assess and evaluate the types of stress that all or portions of an object or structure will experience when subjected to various types of loading.

C. Assess and predict the specification of machine parts and structural members by applying theory to practical problems encountered in design consideration.

D. Utilize structural and material tables and charts.

E. Employ computerized beam analysis tools.
