Course Description :

Concept of stress and strain, axial loading, Hooke’s law, members deformation under axial loading, torsion, design of transmission shafts, pure bending, analysis and design of beams for bending, deflection of beams, energy methods of structural analysis, and Castigliano’s theorem.

Course Objectives :

The main objective of this course is to provide future aeronautical engineers with the means of analyzing and designing various load bearing structures. Students will learn to analyze the stresses and deformations of various structural components subjected to axial loading, torsion and bending as well as its application to the design of simple structures.

Course Intended Learning Outcomes :

By the end of this course, the student will be able to:
  1. Use the Stress-Strain diagram for ductile as well as brittle materials and the mechanical properties associated with it.
  2. Analyze bars under mechanical and thermal loadings.
  3. Analyze the stresses and strains in members of circular cross section subjected to torsion.
  4. Analyze the stresses and strains in prismatic members subjected to bending.
  5. Identify different types of structural loading.
  6. Use the shear and bending-moment diagrams for beams subjected to various supports and loading conditions to calculate the maximum normal stress due to bending.
  7. Determine the deflection of a beam under a given bending loading.
  8. Determine the strain energy in simple structures for normal stresses and shearing stresses.
  9. Apply the work and energy method to analyze simple structures.
