003 (part 1 of 2) 10.0 points A carpenter's square of uniform density has the shape of an L, as shown in the figure. Assume: A (x, y) coordinate frame with the origin at the lower left corner of the car- penter's square. The x-axis is horizontal and to the right. The y-axis is vertically upward. Given: In the figure, B = 14 cm, C = 3.5 cm, D = 4.1 cm, E= 18 cm. Because the square is uniform...

Tactics Box 7.1 Finding the center of gravity.
Even though you can locate an object's center of gravity by
suspending it from a pivot, this is rarely a practical technique.
More often, we would like to calculate the center of gravity of an
object made up of a combination of particles. The following Tactics
Box shows how to find the center of gravity of any number of
particles.
