    Study Notes

    Mechanical Properties of Fluids

    • Fluids move when acted upon by a force or a pressure gradient.
    • Understanding fluid behavior often requires simplifying assumptions.
    • An ideal fluid is defined by specific properties:
      • Incompressible: Density remains constant.
      • Irrotational: Fluid flow is smooth without turbulence.
      • Nonviscous: No internal friction or viscosity present.
      • Steady flow: Velocity at each point does not change over time.

    Distinctions Between Solids and Fluids

    • Solids can resist both shear stress and normal stress, a fundamental difference from fluids.
    • Fluids cannot maintain a fixed shape and lack the ability to resist external shear stresses permanently.
    • The term "fluid" is often associated primarily with liquids due to their definite volume and shape characteristics.

    Fluid Behavior

    • Fluids are characterized by:
      • Static Equilibrium: They cannot oppose their static equilibrium state indefinitely.
      • Containerability: Fluids can adapt to the shape of their containers.
    • Gases are classified as fluids; however, they lack a definite volume and will deform under shear stress.

    Additional Context

    • The term fluid encompasses liquids, gases, plasma, and other substances with similar dynamic properties.
