Everything is off course theoretical.
The weight of the boat is the same in both examples.
The weight of the fuel is also the same, 2 lb. (Small RC boat)
The area of one big tank is the same as the area of the two small combined, meaning length of all tanks will be the same.
If you ballance on a thin rope, why do you lift arms up and out if best CoG is keeping arms down close to your boudy?
What do you think?
Harald 1966 said:but why do you take arms up and out to gain ballance and stability?

willem2 said:If you're walking on a rope your center of gravity will be above your feet, so you
will be unstable anyway. If you stand still you'll fall. To keep upright you have to
move your arms.
If you start falling to the right, you can stick an arm out to the right and move the
rest of your body somewhat to the left. This will move your center of gravity to the
left, so you can stop falling.
Why do you need a calculation? Is this a homework problem?Harald 1966 said:Can anyone please help me compare them by doing a simplyfied calculation?
The center of gravity is the point at which an object's entire weight is concentrated and through which the force of gravity acts. It is also known as the center of mass.
The center of gravity can be calculated by finding the weighted average of all the individual points of an object. This can be done by dividing the sum of the products of each individual point's mass and distance from a reference point by the total mass of the object.
The center of gravity is affected by the distribution of an object's mass. Objects with a more spread out mass have a lower center of gravity, while objects with a more concentrated mass have a higher center of gravity. The shape and size of an object also play a role in determining its center of gravity.
The center of gravity is important because it helps determine how stable an object is. Objects with a low center of gravity are more stable and less likely to tip over, while objects with a high center of gravity are less stable and more likely to tip over.
The location of an object's center of gravity directly impacts its balance. If an object's center of gravity is not aligned with its base of support, it will be off balance and may fall over. Maintaining a low center of gravity is important for maintaining balance and stability.
