There are two methods for weighing airplanes. The first is to actually put the airplane on a set of scales, one under each wheel, and determine the weight that way. The other, common for large aircraft, is to calculate the weight. When a new aircraft is certified by the FAA, it is actually weighed at the factory and an empty weight is determined for each model. The aircraft weight is then recalculated for any changes made to that model. When an airline buys a fleet of the same model aircraft, it determines a basic operating weight (BOW) for the fleet. BOW is the empty weight of the aircraft with the weight of normal operational stores added. These include such items oil and other fluids, spare parts, galley stores, emergency equipment, normal crew, etc...basically, everything except fuel, passengers and cargo. When an aircraft is ready for a flight, its weight is determined by starting with the BOW and adding the actual weight of everything that has been added to the aircraft for that flight. These normally include the actual fuel load, the weight of the passengers (either actual weights if the flight is critical, or average weights if not), the actual or average weight of bags, and the actual weight of the cargo. The end result is the aircraft take-off gross weight (TOGW), which is then used to determine the expected performance of the aircraft (how high it will be able to fly, how fast, etc.). The en route fuel burn is calculated and then subtracted from the TOGW to get landing weight which is used to determine landing performance (how much runway will be needed, stopping distance, etc). Hope that helps.
A platform beam balance is a type of weighing scale that uses a horizontal lever with a platform on one side for placing the object being weighed and calibrated weights on the other side to determine the weight of the object. It is commonly used for measuring the mass of objects in laboratory settings or industrial environments.
You need a lot of gas to do this, but you start by weighing an empty cylinder. You then put a measured quantity of gas in the cylinder and weigh it again.
To use a platform balance, place the object you want to weigh on the platform and wait for the balance to stabilize. The balance will then display the weight of the object. Make sure to read the measurement carefully and remove the object once you have finished weighing it.
Either manual or electronic weighing scales.
You weigh an object to determine its mass. Weight is directly proportional to mass, and in fact most balances are calibrated in mass units such as kilograms.
The weight is the mass multiplied by the acceleration of gravity. When weighing an object by a balance the acceleration of gravity is on both sides of weighing and hence canceling its effect and hence you get the object mass (not the weight)..
by size,volume and gravity
A weighing machine will give you the mass of an item. The weight of an item is the amount of force that an item exerts on the earths surface.
The weight is the mass multiplied by the acceleration of gravity. When weighing an object by a balance the acceleration of gravity is on both sides of weighing and hence canceling its effect and hence you get the object mass (not the weight)..
When the weight of one object is found to be greater than the other. Either weighing up both by holding in your hands, or by weighing them on a scale. Obviously, if an iron bar is next to a piece of wood of the same size the iron would be the heaviest.
False
The buoyant force on an object is equal to the weight of the fluid it displaces. In this case, the object displaces a volume of water weighing 10 N, so the buoyant force acting on the object is 10 N. This force acts upward, countering the weight of the object, which is 50 N. Thus, the object will sink since its weight is greater than the buoyant force.
A weighing scale is used to measure the weight of an object or a person by using the force exerted by gravity on the object being weighed. It is commonly used in various settings such as households, industries, and laboratories to determine mass and ensure accurate measurements for a variety of applications.
The smallest upthrust force needed for an object to float is equal to its weight. So, for an object weighing 1600 N to float, the upthrust force needs to be at least 1600 N. This is because the upthrust force is equal to the weight of the fluid displaced by the object, which in this case is equivalent to the weight of the object.
To accurately determine the weight of a barbell, you can use a scale specifically designed for weighing barbells. Place the barbell on the scale and read the weight displayed. This will give you an accurate measurement of the barbell's weight.
Basically by weighing it. Although mass is not the same as weight, if you know the weight and the gravity, you can calculate the mass.Basically by weighing it.
