Objectives:          The effects of forces and motion on the performance of physical systems is of general importance across the broad spectrum of engineering.  This course is designed to develop within sophomore engineering students working competency in analyzing physical systems under the influence of various force systems, especially with respect to internal stresses and deformations for structural members.

 Topics:            The following specific topics will be covered in the class: 

1.   Introduction; forces and stresses; axial, bearing and average shear stresses; factor of safety.

2.   Stress and strain, axial loadings and normal stresses and strains; shear stresses and strain; mechanical properties of materials; stress-strain curves; 1-D, 2-D, and 3-D Hooke’s Laws; thermal strains and stresses.

3.   Applications of Hooke’s 2-D Law to thin walled pressure vessels.

4.   Deformation of members under axial loads and axial indeterminate problems.

5.   Stress at a point, stress transformations and Mohr’s Circle

6.   Torsion: torsion stresses in circular shafts, deformations and angle of twist, statically indeterminate shafts.

7.   Bending: pure bending and normal stresses and stress distribution.

8.   Beam shear stresses: determination of shear on a horizontal plane and beam shear stresses, shear flow, shear stress distributions and maximum shear stresses.

9.   Shear, moment and thrust diagrams.

10. Combined stresses: combined normal stresses, combined shear stresses.

11. Bending of members of several materials and transformed sections.

12. Column buckling.
