Never mind. I got it on my own. We had to figure the mass of the barge, and used Archimedes principle about fluid displacement and worked it out from there. Thanks for anyone who might have been trying to help.
A barge made of metal can float in water because of its shape and displacement. The barge is designed to displace a volume of water that is greater than its own weight, allowing it to float. Additionally, the buoyant force acting on the barge provides the necessary upward force to keep it afloat.
If you add more sand the barge will be weighed down taking away height from the barge. If you take away sand, the barge will float higher and have an even better chance of not being able to fit under the bridge.
You calculate the volume of water displaced (volume of hull up to the waterline level), and multiply by the density of the water in which it will float.
It will float because water has more density than air and barges have air in them
6 MegaNewtons is the weight of (6 x 106 / 9.8) kilograms of water, equivalent toa volume of (6 x 106 / 9.8) liters of water, or (6,000/9.8) cubic meters of water.That's the additional displacement the barge has to achieve as soon as the load drops,in order to float with the additional weight.The added displacement is (10 x 60 x D) cubic meters, where 'D' is the added depth.(10 x 60 x D) = (6 x 103 / 9.8)D = 6 x 103 / (9.8 x 10 x 60)D = 1.02 meters (rounded)
It does if you spread it in to a boat or barge shape because other than that it will just sink.
Consider the following - a submerged object displaces its volume, but a floating object displaces its weight. You also know (or can assume) the load is evenly distributed. So you can take the weight of the load (the horse) and apportion the displacement evenly across the boat. Now you are better prepared to calculate the answer.
If the weight of displaced water is greater than the weight of an object, the object will float. This is known as Archimedes' principle, where the buoyant force exerted on the object is greater than its weight, causing it to float.
Any object which displaces an amount of liquid equal in weight to it's weight will float.
A 1000-gallon tank can float if it displaces a weight equal to or greater than its own weight. The weight it can float depends on the density of the liquid it's floating in. For example, in water, the tank would float if it displaces 1000 gallons of water (which weighs about 8,345 pounds).
markers float because they are less weight. and it doesnt have metle on it.
Your weight is the same on land as on the water.
