ENGR& 225 - Mechanics of Materials

• Apply the concepts of normal and generalized shear stress to members in compression/tension, torsional and shear situations.
• Draw a stress versus strain diagram for members in tension, and discuss the elastic versus plastic region, yielding, strain hardening, necking, ultimate stress, fracture stress and true versus engineering diagrams.
• Describe the relationship between stress and strain using Hooke’s Law and Poisson’s ratio for 3-dimensional problems.
• Determine the deformation of axially loaded members and calculate support reactions for statically indeterminate problems.
• Calculate thermal stress and inelastic deformations and determine stress concentration factors.
• Calculate shear stress caused by torsion and calculate support reactions for statically indeterminate torque-loaded members.
• Calculate normal and shear stresses in a cross-section of a symmetrical beam.  This includes shear and bending moment diagrams, finding centroids, moments of inertia and the section modulus and applying the flexure and shear formulas.
• Draw Mohr’s circle and use it to determine principal stresses and maximum shear stresses and the orientation at which these stresses will occur..
• Use effective techniques to define problems, gather information, analyze data, perform critical evaluations, implement solutions, and communicate the results.
• Use appropriate mathematical, sketching and modeling skills to describe concepts and systems.
• Apply the engineering design process to a group project and present the results using current technology.
