A basic study of strength and rigidity of mechanical elements in tension, compression, shear and bending. Students will encounter and solve mechanical design problems involving stress and deflection of tension compression and direct shear members, shafts in torsion, beams in bending, and columns in compressive buckling. This course will also include the study of stress on connections such as weldments, riveted elements and bolted elements and the effect of stess concentration. The importance of basic design concepts such as stress, strain, deflections, elastic moduli, yield strength, ultimate strength, stiffness and safety factor are explored.
