Question:

Aluminum foil boat with egg as cargo?

Im working on a report where we have to build a boat out of aluminum foil that will hold an eggWhat are the physics of the floating boat to build a better boat? Any equations and/or calculations relating to buoyancy would be helpfulThank you!

Answer:

basically the boat must be big enough so that it displaces the weight of it and the egg with water that is weigh the egg, calculate how much water that is by: weight egg in kg/1000 number of cubic meters the boat will displace all those calculations are fine but the boat shape will make things very hard, basically make sure the boat is deep enough to sink enough in the water to displace a bit over an egg's worth of water without willing with water itselfthe most important thing to do is to make the boat stable in water, that is, you want its center of mass to be below the water line so that it stays as upright as possible, to accomplish this a smaller but deeper boat would be best, although a larger boat would also accomplish the same thing by giving the water more torque to resist tipping these are just theoretical ideas, it is probably a bit overwhelming but in a case like this the physics become less important than common sense
