Strength of Materials
Course description
The course covers the following topics; stress and strain concepts, axial load, statically indeterminate axially loaded members, thermal stress, torsion, angle of twist, bending, transverse shear, combined loading, stress and strain transformation, deflection of beams and shafts, statically indeterminate beams and shafts, buckling of beams.
Purpose of class
1. To provide the basic concepts and principles of strength of materials.

2. To give an ability to calculate stresses and deformations of objects under external loading.

3. To give an ability to apply the knowledge of strength of materials on engineering applications and design problems.
Goals and objectives
