H-02 Hydrostatic Pressure
Analysis
Experiment : in this experiment the thing that differnet from the modul that the measurement alredy given
Result :
Theres High RE in the Linear Equation
Linear increasing of the graph
Error :
Human
Reading
Conclusion
We can get the formula 3 and 5 from simplifying the sigma Moment from formula 1 and 2
The increase of the mass will equal to the increase of the water, because if we add the mass we need to add the water to neutralize the moment caused by mass

Analysis
Experiment:
Submerged volume = Inertia
Hanging the ponton = Center gravity
Result: the value of GM from 200 to 300 is decreasing
Error:
Human
Reading
Conclusion
GM depeng Center Gravity, Center gravity depend shear load position
GM depend on the volume of submerged pontoon, the volume depend on shear load position
GM is equal to the gap between floating point metacentrum point with the distance from the pontoon
GM>0 or GM=0 is stable
