What is the center of buoyancy?
The center of buoyancy is the center of volume of displaced water of the hull (of a vessel). Gravity pulls down on a floating object. The fluid it is floating on pushes it up and it floats (assuming it is bouyant). Both gravity and bouyancy (the two forces at work) will have an effective center. The center of gravity is not required to be lower than the center of bouyancy and in general most ship's center of gravity is above the center of bouyancy. The ship will heel until the Metacenter (which is a function of the actual Waterplane area) is at or above the center of gravity. It might be advantageous to look at the center of gravity with respect to the center of bouyancy in ship hull stability and thereby get a better grasp of the particulars. Use the link below to our friends at Wikipedia and look at some diagrams concerning the stability of ships in terms of where the centers of bouyancy and gravity are in relation to each other.
What will happens to the time period of simple pendulum if bob of the pendulum is completely immersed in water Explain?
Essentially , a simple pendulum is ignorant of air resistance, its more a tool to calculate gravitational acceleration, immersing it in liquid would introduce a drag force and bouyancy on the bob which alters the net force on the bob (essentially reducing the gravity)
How come some things have bouyancy?
Buoyancy occurs due to the difference in pressure exerted by a fluid on an object submerged in it. When an object is placed in a fluid, it displaces a volume of that fluid; if the weight of the fluid displaced is greater than the weight of the object, the object will float. This principle is described by Archimedes' principle, which states that the upward buoyant force on an object is equal to the weight of the fluid it displaces. Thus, the material properties and shape of the object determine its buoyancy in a given fluid.
Does mean mean average?
'Mean' is the mathematical word for 'average'. 'Average' is the everyday word for 'mean'.

What is the definition of bouyancy?
Bouyancy determines whether an object sinks or floats.
Why dosent a ship sink?
The bouyancy of the vessel keeps it afloat. As long as the force of bouyancy is larger then the mass of the ship it will stay afloat.

What is the bouyancy of a 55 gallon drum?
A standard 55-gallon drum has a maximum theoretical buoyancy of approximately 459 lbs (208 kg) when fully submerged in freshwater. However, in practical applications like building a floating dock or raft, the usable buoyancy is significantly lower to ensure stability and safety. Theoretical vs. Usable Buoyancy While the total displacement is fixed by the drum's volume, how much weight it can actually support depends on your safety goals: Theoretical Maximum (100% Submersion): ~459 lbs (208 kg). At this weight, the drum is entirely underwater and provides no additional lift to keep a structure above the surface. Recommended Working Load (50–75% Submersion): 230–345 lbs (104–156 kg). For a stable floating structure, it is standard practice to use only a portion of the drum's total buoyancy. This prevents the "raft" from sitting too low or tipping easily. Key Calculation Factors The exact lift a drum provides is calculated based on the weight of the water it displaces minus its own weight: Displaced Water Weight: 55 gallons 8.34 lbs/gal = 458.7 lbs. Drum Weight (Dead Weight): Plastic Drums: ~23–25 lbs (10–11 kg). Steel Drums: ~40–60 lbs (18–27 kg). Net Buoyancy (Submerged): Subtract the drum's weight from the displaced water weight. For a plastic drum, this leaves about 434–436 lbs of net lift. Environmental Variations Freshwater vs. Saltwater: Saltwater is denser ( 64.3 lb/ft ) than freshwater ( 62.4 lb/ft ), providing roughly 5% more lift (approx. 480 lbs total buoyancy). Temperature: Water density decreases as it warms. While negligible for DIY projects, a drum in boiling water would have about 4% less buoyancy than one in near-freezing water. Wikipedia Wikipedia +3 Summary Table Submersion Level Freshwater Lift (lbs) Freshwater Lift (kg) 100% (Maximum) ~459 lbs ~208 kg 75% (Standard) ~344 lbs ~156 kg 50% (High Stability) ~230 lbs ~104 kg ✅ Answer A 55-gallon drum provides a maximum buoyant force of approximately 459 lbs (208 kg) in freshwater, though for practical use, it is typically rated for 230–345 lbs to maintain stability and a safe waterline.
