Strength of Materials

Students would be capable of the following: 1. Recognition of a structural system that is stable and in equilibrium; 2. Determination of the stress -strain relation for single and composite members based on Hooke's law; 3. Estimation of the stresses and strains in single and composite members due to temperature changes; 4. Evaluation of the distribution of shear forces and bending moments in beams with distributed and concentrated loads; 5. Determination of bending stresses and its use in determining slopes and deflections in beams; 6. Use of Mohr's circle to evaluate the normal and shear stresses in a multi-dimensional stress system and transformation of these stresses into strains; and 7. Evaluation of the stresses and strains due to torsion on circular members.

Consideration of equilibrium; composite members, stress-strain relation. Generalized Hooke's law. Stress and strain transformation equations. Stresses and strains due to loading and temperature changes. Torsion of circular members. Shear force, bending moments and bending stresses in beams with symmetrical and combined loadings. Deflection of beams. Multi-dimensional stress systems. Mohr’s circle. Elastic buckling of columns.
