correct? o Compared to Gas, liquid has very small cohesive force. Therefore, liquid can form a free surface in a gravitational field. Solid has the strongest intermolecular bond, while gas has the weakest intermolecular bond. Fluid mechanics deals with liquids and gases in motion or at rest. So fluid mechanics include fluid dynamics and fluid statics. Both liquid and gas belong to fluid. When a constant shear force is applied, fluid never stops deforming and reach a constant rate of strain.

Equilibrium and Support Reactions

Civil engineers deal with structures that are composed of several members connected or with individual members such as beams and columns. To analyze such structures, the condition of statics must be applied. Under the static condition, the members are considered to be in equilibrium under the action of forces, that is, the members are assumed to be having negligible velocity.
