5. UCSD POLICY ON INTEGRITY OF SCHOLARSHIP Students' Responsibility Students are expected to complete the course in compliance with the instructor's standards. No student shall engage in any activity that involves attempting to receive a grade by means other than honest effort; for example:�No student shall knowingly procure, provide, or accept any unauthorized material that contains questions or answers to any examination or assignment to be given at a subsequent time. No student shall complete, in part or in total, any examination or assignment for another person. No student shall knowingly allow any examination or assignment to be completed, in part or in total, for himself or herself by another person. No student shall plagiarize or copy the work of another person and submit it as his or her own work. No student shall employ aids excluded by the instructor in undertaking course work or in completing any exam or assignment. No student shall alter graded class assignments or examinations and then resubmit them for re-grading.Any breach of academic honesty will be considered grounds for failure in the course

7. MECHANICS: That science, or branch of Physics, which treats of the action of forces on bodies. That part of mechanics which considers the action of forces in producing rest or equilibrium is called Statics ; that which relates to such action in producing motion is called Dynamics. The term mechanics includes the action of forces on all bodies, whether solid, liquid, or gaseous. It is sometimes, however, and formerly was often, used distinctively of solid bodies only FLUID MECHANICS: The branch of Physics, which treats of the action of forces on fluids. In the case of liquid is called also Hydrostatics, or Hydrodynamics, according as the laws of rest or of motion are considered. Aerodynamics: The mechanics of bodies moving in the atmosphere The mechanics of gaseous bodies is called also Pneumatics.

8. Fluid A continuous, amorphous substance whose molecules move freely past one another and that has the tendency to assume the shape of its container; a liquid or gas.

9. Fluids share the properties of not resisting deformation and the ability to flow. These properties are typically a function of their inability to support a shear stress in static equilibrium. While in a solid, stress is a function of strain, in a fluidstress is a function of rate of strain.
