Please explain what you mean by that statement.nwmyname said:It sinks 52.5% of the water.
The density of the object is 525 kgm-3 and the density of the water is 1000 kgm-3 so it must be sink 52.5% into the water?haruspex said:Please explain what you mean by that statement.

A much more useful application of Archimedes' Principle would be to find out the draft that the block must float at such that the weight of water displaced by the block is equal to the weight of the block itself. The draft of the block is that distance the bottom sinks below the surface of the water, and given the shape of the block, a trivial calculation.nwmyname said:Homework Statement
A block of wood measures 2.2m by 2.5m with depth 3.6m with weight 102KN. When placed in water, how far will it sink?
g = 9.81 ms-2
density of water = 1000kg m-3
Homework Equations
The Attempt at a Solution
Volume = 2.2(2.5)(3.6) = 19.8m3
Mass = 102000 / 9.81 = 10398 kg (nearest whole)
Density = 10398 / 19.8 = 525 kg m3
It sinks 52.5% of the water.
How to continue finding how far it will sink?
It sinks 52.5% of what into the water? 52.5% of the block?nwmyname said:The density of the object is 525 kgm-3 and the density of the water is 1000 kgm-3 so it must be sink 52.5% into the water?
Archimedes' Principle is a law of physics that states that the buoyant force on an object in a fluid is equal to the weight of the fluid that the object displaces.
According to Archimedes' Principle, the distance an object sinks in a fluid is determined by the weight of the fluid that the object displaces. The more fluid an object displaces, the greater the buoyant force acting on the object, which causes it to sink deeper into the fluid.
The distance an object sinks in a fluid is affected by the density of the fluid, the density of the object, and the volume of the object that is submerged in the fluid. These factors determine the weight of the fluid displaced and therefore the buoyant force acting on the object.
Yes, Archimedes' Principle is a universal law of physics and can be applied to all fluids, including liquids and gases.
Archimedes' Principle is used in many real-world applications, such as shipbuilding, submarine design, and hot air balloons. It is also used in determining the densities of objects and fluids, and in understanding the behavior of objects in fluids.
