Computers on modern ships have built in control circuits to balance the vessel. This is done by using the math of subtracting angles. The computer determines the degree of the angle of list by using angular subtraction from the vertical reference line. The computer then activates bilge pumps to alter the amount of water held in the different ballast tanks of the ship resulting in restoring the vertical position of the vessel.

 

Thanks Pi!

We provide an in-depth video of how it's done. Simple. Easy. Fun!

 

4.712m needs to be converted to mm.

4.712m = 4712mm

C ÷ p= d

circumference ÷ p = diameter

4712 ÷ p = 1500mm
