Fluid Materials

In general terms, anything that flows can be termed as a fluid. In other words, a fluid is any substance that cannot resist shear forces and deforms continuously under the application of external shear forces. Fluid materials differ completely from solid materials such as metals and alloys. For instance, if we consider two infinitesimally small cross-sectional areas of fluid materials and solid materials, and apply shear forces to these elements, both the elements will undergo deformation. Upon releasing the shear force, the element of the solid materials will regain its original orientation, but the element of the fluid materials will keep on deforming continuously under the action of the shear force.

Learning Goal: To replace force-couple systems with an equivalent force by specifying the magnitude and direction of the equivalent force and the location where the force needs to be applied. Certain force-couple systems can be replaced by a single force. The requirement is that the lines of action of the resultant force, FR, and the resultant couple moment, (MR)o, are perpendicular to each other. This is equivalent to saying the following types of force systems can be simplified to a single force: Figure F₂ X F₁ 3 ft A B 2 ft < 2 of 3 C
