ENGR2520 Mechanics of Materials

Course Description

This course introduces students to the fundamental concepts of mechanics of materials and basic properties of engineering materials. It covers stresses deformations, stress-strain relationships, torsions, beams, shafts, and columns, elastic deflections in beams, combined loading, and combined stresses. Students will be familiarized with the analysis and design of structural member under axial loads, torsion, bending, shear, and combined loading.

Student Learning Outcomes

  • Understand the vital concepts of stress, strain, failure, and strain energy.
  • Draw a perfect free body diagram to check the equilibrium of a rigid body.
  • Define elastic limit, yield strength, ultimate strength, and modulus of
  • Describe ductile and brittle behavior of materials.
  • Calculate stress and strain in axial loading.
  • Analyze and design structural member under axial and torsional loading.
  • Define plastic deformation in circular shafts.
  • Differentiate between normal stress and shear stress, extensional
    strain and shear strain and the corresponding material properties.
  • Utilize Mohr's circle method to determine principal stresses, principal
    planes, and maximum shear stress under numerous combinations of bending, torsion, and axial loads.
  • Compute the acute buckling load of a column.
  • Utilize the equation of elastic curve to calculate deflection.
  • Investigate statically indeterminate structures.
  • Design simple bars, beams, and circular shafts for tolerable stresses and loads.
