Concept explainers

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.

Question

Learning Goal:
To be able to find the center of gravity, the center of mass, and the
centroid of a composite body.
A centroid is an object's geometric center. For an object of uniform
composition, its centroid is also its center of mass. Often the
centroid of a complex composite body is found by, first, cutting the
body into regular shaped segments, and then by calculating the
weighted average of the segments' centroids. An object is made
from a uniform piece of sheet metal. The object has dimensions of
a = 1.25 ft, where a is the diameter of the semi-circle, b = 3.71 ft,
and c = 2.30 ft. A hole with diameter d = 0.750 ft is centered at
(1.09, 0.625).
