NVCC COLLEGE-WIDE COURSE CONTENT SUMMARY
EGR 246 - MECHANICS OF MATERIALS (3 CR.)

COURSE DESCRIPTION

Teaches concepts of stress, strain, deformation, internal equilibrium, and basic properties of engineering materials. Analyses axial loads, torsion, bending, shear and combined loading. Studies stress transformation and principal stresses, column analysis and energy principles. Lecture 3 hours per week.

GENERAL COURSE PURPOSE

The course will introduce the student to the fundamental principles of stress and strain relationships in structures. It will also provide techniques for handling transformation of stresses, deflection of beams. It will prepare the student for structural design and the ability to progress to elasticity, shell and plate theories in advanced structures.

ENTRY LEVEL COMPETENCIES

Competence in statics. Prerequisite: EGR 140.

    3. understand the means of calculating principal stresses
    4. understand the criteria of failure of a structure
    5. understand the means of insuring stability in the structure
    6. design simple structures
