Archimedes' thrust is the vertical force oriented

upwards experienced by a body immersed in a liquid (allowing it to float).

This force corresponds to the weight of the volume of the displaced liquid. For example, a

object immersed in water (density 1000 kg / m3) will undergo a flare

of Archimedes of 9810 N for each cubic meter of its submerged volume (i.e. 9, 81 m / s2 * 1000 kg / m3 * 1 m3 = 9810 N).

A buoy is made from a steel tube 4 meters long and 0.5

radius meter to which we welded a half-sphere at each end. Knowing

that the weight of the buoy is 3630 N say what will be the immersion height of

this buoy if it is submerged in fresh water (density 1000 kg / m3).
