The three-dimensional structure shown is fabricated from five thin steel rods of equal diameter. Write a computer program that can be used to calculate the coordinates of the center of gravity of the structure. Use this program to locate the center of gravity when (a) h = 12 m, R = 5 m, α = 90°; (b) h = 570 mm, R = 760 mm, α = 30°; (c) h = 21 m, R = 20 m, α = 135°.
