Floatable FoundationJohn Tobias, Brian Jestice,

Anthony Cairns, Diane Kohlin

What it is?It is a foundation ,that can float, for a

dwelling so if the land floods the dwelling will just float instead of being destroyed.

Where would they use it?The Republic of South Africa is a country

located at the southern tip of Africa, with a 2,798 kilometers (1,739 mi) coastline on the Atlantic and Indian Oceans.

Testing the Model

CalculationsFinding an average density of muddy water

by comparing the densities of dirt and water in a 1:5 ratio:

2002*1/6=333.6667kg/m3

1000*5/6=833.3333kg/m3

333.7+833.3=1,167kg/m3

density of muddy water: 1167 kg/m3

CalculationsFinding the amount of water the frame of a

whole palate could displace at a maximum.

(3)(.50)(5.5)(32)+(2)(1.5)(50.25)(3.5)+(9)(.5)(3.5)(32)=264+527.625+504=1295.625in3

1295.625in3= 0.0212 m3

CalculationsAmount of Water displaced by bottles:14 bottles.002m3 minimum volume of one bottle14(.002m^3)= .028 m3

CalculationsFinding the total amount of weight the foundation

can hold, accounting for only the bottles:

∑Forces = 0 = mgρfluidVdisplacedg

mg= ρfluidVdisplacedg

mmax= ρfluidVdisplacedggmmax=ρfluidVdisplaced

mmax=(1167kg/m3)(.028m3)= 32.676 kg

CalculationsAmount of weight the foundation can hold

only accounting for the frame:∑Forces = 0 = mgρfluidVdisplacedg

mg= ρfluidVdisplacedg

mmax= ρfluidVdisplacedggmmax=ρfluidVdisplaced

mmax=(1167kg/m3)(.0120m3)=14.03kg

CalculationsRatio of the frame used to the total size of

one palate: 28.5/50.25= 56.72%Therefore the net mass able to be supported

by 56% of the palate (current model) is: 14.03kg+32.676kg=46.708kg=102.97 lbs

Therefore it can be concluded that a full scale palate is able to support 83.4kg=183.86lbs
