ENES 220 - Mechanics of Materials

Distortion of engineering materials in relation to changes in stress or temperature. Geometry of internal strain and external displacement. Elementary applications of beams, columns, shafts, tanks, trusses, and connections. PREREQUISITE(S): A grade C or better in ENES 102 . PRE- or COREQUISITE(S): A grade C or better in MATH 182 . Three hours each week. Formerly ES 220.

3 semester hours

Course Outcomes:
Upon course completion, a student will be able to:


  • Define basic concepts of stress, strain and their relations based on linear elasticity.
  • Analyze material behaviors due to different types of loading.
  • Calculate stresses and deformations of a bar due to an axial loading under uniform and non-uniform condition.
  • Compute stresses and deformation of a torsional bar
  • Draw shear-moment diagram of a beam and find the maximum/shear and their locations
  • Calculate normal and shear stresses on any cross-section of a beam.
  • Construct and apply Mohr’s circle to find the principal stresses, maximum shear, corresponded angles and stresses in any inclined plane.
  • Define stresses on a structure under combined loading.
  • Solve the deflection of a beam under combined loads by using method of moment-area and superpositions.
  • Explain stability and buckling phenomena for a slender member under an axial compressive force.
