CE 1161 FLUID AND SOLID MECHANICS 3 1 0 100
OBJECTIVE
At the end of this course the student is expected to have a knowledge of the concepts of Forces, Equilibrium, Stress, Strain, Shear force, Bending moment and torsion and should be able to apply these concepts to simple problems in beams and shafts. Further, he /she is also expected to gain knowledge of the fundamentals of fluid flow and their applications to flow through pipes and hydraulic machines. He / She should be able to solve application problems in these
areas.
