Solve the below problem:
Q: Three brass plates are brazed to a steel pipe to form the flagpole base shown. Knowing that the pipe has a wall thickness of 0.25 in. and that each plate is 0.2 in. thick, determine the location of the center of gravity of the base. (Specific weights: brass = 0.306 lb/in3, steel = 0.284 lb/in3)
