Course Description:
CEGR 301 Mechanics of Materials and Lab - Three hours lecture, three hours laboratory; 4 credits.
                  Introductory analysis of tension, compression and shear. Analysis of stress and strain, ties, shafts, beams and columns. Related laboratory experiments. Introduction to structural analysis and design.
Prerequisites:  MATH 242 (Calculus II), PHYS 205 (General Physics I) and CEGR 304 (Engineering Mechanics).
Course Objective: Development, through class instruction, discussion, and assignments, and laboratory work, of experiences and understanding of physical behavior and structure of practical materials and components, especially as represented by the state of stress, strain, and deformations. Provision of method and ability for the systematic analysis and design of components of structures and machines.
