ES 209 - Mechanics of Materials Credit Hours: 3
A course in the study of strength and elasticity of materials, stresses and strains; deflection of beams and shafts; torsion and buckling of columns.
Course Outcomes At the conclusion of this course, the student should be able to:
- determine tensile and compressive stress and strain in axially loaded members and structures;
- draw free body diagrams;
- understand stress-strain diagrams and related terminology;
- understand and use formulas to compute forces, normal stress and strain, and shear stress and strain. Calculate stress, strain;
- analyze thermal effects on stress and strain; and
- analyze indeterminate structures using compatibility conditions.
- analyze members subjected to torsion;
- determine torsional deformation in a circular bar;
- calculate power transmission; and
- calculate strain energy in torsion and pure shear.
- analyze shear force and bending moments in beams;
- determine reactions at supports and shear force and moment along beam;
- graph shear force and moment diagrams;
- determine the curvature of a beam, neutral axis and moment of inertia; and
- calculate normal stress and shear stress in beams subjected to bending moment.
- analyze stress and strain;
- compute principal stresses, maximum shear stresses; and
- draw and interpret Mohr’s circle for plane stress and strain.
- calculate stresses in spherical and cylindrical pressure vessels;
- determine the deflection of a beam under concentrated loads and distributed loads; and
- obtain beam deflection by integration of the bending-moment equation;
- obtain beam deflection by integration of the shear-force and load equations; and
- obtain beam deflection by method of superposition, moment-area method and the application of Castigliano’s Theorem.
- determine the critical bucking loads for columns under various types of supports.
