HFC30 Archimedes Principle Trainer

Penjelasan Produk

The Archimedes principle states: The magnitude of the buoyant force equals the weight of the fluid that the object displaces. When the test objects are suspended the moment lever arm is brought to the horizontal by moving the balance hanger and monitoring the small spirit level until level. When the test object is lowered into the fluid the counterweight is adjusted to bring the moment lever arm back to the horizontal. The change in position of the counterweight gives rise to a reduced moment thus indicating the magnitude of the buoyancy force being applied to the object. An alternative method of measuring the buoyancy force is to measure the amount of fluid displaced when the object is floating in the fluid tank.
