Problem 1
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 = 1.20 ft ,b= 3.74 ft, and c = 2.45 ft. A hole with diameter d = 0.600 ft is centered at (1.00, 0.600).
Find z, y, the coordinates of the body's centroid. (Figure 1)
Express your answers numerically in feet to three significant figures separated by a comma.
