Discussion
The force applied in the system vertical face of buoyant material counter acts the mass
added to the hanging arm. so we know that if we move away from the sea level, the
pressure will change either with air or water. So in our experiment also change in
pressure because of the weight of the water above and buoyant forces clearly show the
properties of water. The water pressure was so high that we add the mass 50 g to 450g
even still quadrant was able to support it in static equilibrium. So the idea let us to believe
that the curved area allows for a larger surface with which the water can act upon for less
change in depth. This would explain such a large jump in force applied after breaking the
upper plane of the vertical face.
Conclusion
The graphical analysis of our lab shows that a linear relationship between Hydrostatic
force and Average Depth for the Partially Submerged and the graph of Hydrostatic Force
and Average Depth for Fully Submerged is also linear. Our Theoretical force compared
to the measured force were nearly identical with a percent errors of 2.04e^-14%. The
error in the distance to the centre of pressure compared to the theoretical was
outrageously high with a percent error of 50.42%. The graphical analysis showed a
linear relationship between Hydrostatic Force and Average Depth for only fully
submerged. The graph of Hydrostatic Force and Average Depth for partially submerged
is not perfectly linear.
