3. Given the modified steel section (added plate) shown in the diagram below, locate the centroid of the section relative to the bottom of the beam. Calculate the area moment of inertia of the modified section about the x axis through the combined centroid. Note that the section properties of the W14x82 are given in Appendix Table A3 of the textbook (Onouye).

Fluid Kinematics

The branch of science that deals with objects which are either in motion or stationary are studied under the branch of classical mechanics. Fluid mechanics is a subcategory of classical mechanics that deals with the behavior of fluids at rest (fluid statics) or in motion (posing some velocity). In fluid kinematics, studies focus on the associated motion of fluid particles or groups of particles, and its associated parameters like displacements, velocity, and acceleration without concerning about the forces that caused the motion. All the laws of classical mechanics are applied in the study of fluid kinematics.
