9. Keywords Mechanics of materials, Strength of materials, Structural Engineering, Civil Engineering, Structural analysis.
10. Course overview: The course covers the following topics; stress and strain concepts, axial load, statically indeterminate
axially loaded members, thermal stress, torsion, angle of twist, , bending, eccentric axial loading of
beams, transverse shear, shear flow in build-up members, combined loadings, stress and strain
transformation, design of beams and shafts.
11. Course objective: The Course objective is to:
1. Provide the basic concepts and principles of strength of materials.
2. To give an ability to calculate stresses and deformations of objects under external loadings.
3. To give an ability to apply the knowledge of strength of materials on engineering applications and
design problems.
