1.0 TITLE
The title of this experiment is stability of floating body.
2.0 REPORT SUMMARY The report is prepared for the sake of discussing about the principle in fluid mechanics which is the stability of floating body which relates to the concept of centre of gravity and the location centre of buoyancy. The appropriate location these two are matters since they will determine whether or not a random floating body is either stable or not when placed in water. By theory, we know that when the centre of buoyancy point of the body is higher/same than the centre of gravity, hence the body is in neutral stability while if the case is opposite, otherwise will happen. Hence, the experiment is conducted to prove this theory and according to the analysis prepared in Section 7.0 (p. 11), the theory is proven to be correct.
3.0 INTRODUCTION
In physics, buoyancy is an upward acting force, caused by fluid pressure, which opposes an object's weight. If the object is either less dense than the liquid or is shaped appropriately (as in a boat), the force can keep the object afloat. This can occur only in a reference frame which either has a gravitational field or is accelerating due to a force other than gravity defining a "downward" direction (that is, anon-inertial reference frame). In a situation of fluid statics, the net upward buoyancy force is equal to the magnitude of the weight of fluid displaced by the body. This is the force that enables the object to float.
