Description of DIDAC Archimedes Principle Trainer Apparatus:
The Archimedes principle states: The magnitude of the 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 counter weight 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. The level before and after immersion is monitored using the integral scale on the outside of the fluid tank. Test object shapes are solid cylinder, cube, sphere and cone are supplied as standard, there are also three identical shapes that are made from different materials, these are aluminium, brass and steel. Each test object is water proofed to avoid inaccuracies of results and corrosion over time. The samples attach to the moment lever arm using a cord and lowered into the fluid tank by lowering the cord accordingly, a scale on the lever arm allows the user to also record the amount of distance the shape has been lowered. The fluid tank can be filled with water or another medium, i.e. anti-freeze, oil etc.
