The main idea at work is the upward force of fluid that opposes the gravitational pull on an immersed object, buoyancy. Water pushes the ship upwards. In Earth, flui…d experience greater pressure the further we go down. This is why we cannot simply go to the bottom of the ocean with a wooden barrel-it will be crushed by the pressure exerted by the water if it will go deep at all. This pressure forces things to go up. And, this force is directly proportional to the weight of the water. This means that things denser than the water will go down. Ships today are made of metal which are denser than the water however, the ship is not composed of only metal. Ships also contain air which is less dense than water. Ships contain more air than metal to decrease its density and become less dense than water to float on it.
Archimedes' principle, principle that states that a body immersed in a fluid is buoyed up by a force equal to the weight of the displaced fluid. The principle applies to both …floating and submerged bodies and to all fluids, i.e., liquids and gases. It explains not only the buoyancy of ships and other vessels in water but also the rise of a balloon in the air and the apparent loss of weight of objects underwater. In determining whether a given body will float in a given fluid, both weight and volume must be considered; that is, the relative density, or weight per unit of volume, of the body compared to the fluid determines the buoyant force. If the body is less dense than the fluid, it will float or, in the case of a balloon, it will rise. If the body is denser than the fluid, it will sink. Relative density also determines the proportion of a floating body that will be submerged in a fluid. If the body is two thirds as dense as the fluid, then two thirds of its volume will be submerged, displacing in the process a volume of fluid whose weight is equal to the entire weight of the body. In the case of a submerged body, the apparent weight of the body is equal to its weight in air less the weight of an equal volume of fluid. The fluid most often encountered in applications of Archimedes' principle is water, and the specific gravity of a substance is a convenient measure of its relative density compared to water. In calculating the buoyant force on a body, however, one must also take into account the shape and position of the body. A steel rowboat placed on end into the water will sink because the density of steel is much greater than that of water. However, in its normal, keel-down position, the effective volume of the boat includes all the air inside it, so that its average density is then less than that of water, and as a result it will float.
While there had been cruise liners for several years, transatlantic crossings with strictly passengers did not begin until about 1901. It was the German ship Prinzessin Vi…ctoria Luise that was first.
102 passengers 2 dogs and 2 babies born on the mayflower. hey thank me
the least expensive accomodation would be tourist class
A cruise ship passenger.
Poor passengers travelled in steerage.
Some cruises are: Royal Caribbean Cruise Norwegian Jewel Princess Cruises Carnival Disney Cruise Line and Star Cruises.
Because the weight of the water that they displace is greater than the weight of the ship.
When the total weight of the ship is less than the weight of the volume of water (salt or fresh) that the ship displaces, it will float. You can make a ship out of steel or co…ncrete, as long as it weighs less than the volume of water it displaces. How sea-worthy the ship is depends on what type of waves or what the possiblity is of the ship taking on water, unless the exterior is sealed. To calculate this, you will need the exterior dimensions of the hull and weight of the ship. I would use the metric system, because the units are easier to convert for this example. Kilograms (1000-grams) for weight and Liters (1000-cubic centimeters) for volumes. Using a volumetric formula (i.e. length x width x height) to obtain the volume you wish to be below the water line. Take the weight of the ship and divide it by the volume you obtained for the ship at or under the water-line. If this number is less than the specific-gravity of fresh water (lighter than salt water) it will float, provided the center of gravity is on the bottom of the ship. (otherwise it may turn up-side down). The specific gravity of water is ~1.0 kilogram per Liter. For example if the volume (LxWxH) displaced (below the water line) by the ship is 100 liters and the weight of the whole ship is 60 kilograms, 60/100 = 0.6 which is less than the water specific gravity 1.0, then it should float. Bear in mind that the ~70% of the weight of the ship should be below the water line or the ship will not have stability (it may turn over). This should also take into account added weight to the ship such as cargo or (God forbid) water.
