Buoyant Hotel
A unique hotel is to be designed with standard cubes 2 m on a side with a mass of 2000kg each.
Four of these cubes will be arranged together to form each room. These rooms will be suspended
from a cable for an underwater (sea water) vacation experience. Several possible arrangements
are shown below:
Assume that the top of each “room” will be placed 10 m under the surface.
 Find the Force on the bottom surface of the room by the water.
 Find the Force on the top surface of the room by the water.
 Find the Buoyant Force.
 Which “room” will ensure the smallest Tension in the cable?
Assume that the top of each “room” will be placed 100 m under the surface.
 Find the Force on the bottom surface of the room by the water.
 Find the Force on the top surface of the room by the water.
 Find the Buoyant Force.
 Which “room” will ensure the smallest Tension in the cable?
Make a recommendation for a hotel design that is safest and gives the best experience for the
traveler. Explain your reasoning.
