A homogeneous charge of solid propellant for a rocket is in the shape of the circular cylinder formed with a concentric hole of depth x. For the dimensions shown, plot , the x-coordinate of the mass center of the propellant, as a function of the depth x of the hole from x = 0 to x = 600 mm. Determine the maximum value of and show that it is equal to the corresponding value of x.
