The base side length of Square Pyramid A is 5 cm. The base side length of Square Pyramid B is 7 cm. What is the ratio of the volume of Square Pyramid A to the volume of Square Pyramid B?

For determining the centroid of the area marked below in blue, you could to consider two square segments: square A B C D and square D E F G. Given: a = 55 m, and b = 18 m, then the coordinate in x direction of the centroid of the following area ABCGFE will be: _________ m.  Calculate your answer to 1 decimal place.

A mechanical part is made up by the union of two triangles, as illustrated in Figure 3. Both triangles have the same base b, height h and uniform thickness w. Each triangle has uniform density, Pj and ez respectively. a. Determine the x-coordinate of the geometrical centroid of each triangle. Justify your reasoning. b. Determine the x-coordinate of the center of mass of the whole mechanical part. Justify your reasoning. y P2 h Pi b Figure 3. Two triangles with equal dimensions and different densities are combined together into one mechanical part.
