Concept
Archimedes’ principle is convincingly demonstrated to show that the buoyant force on a submerged object is indeed equal to the weight of the water displaced by that object. The buoyant force is measured by the observed reduction in the system’s weight as it is submerged in water
Procedure
- Verify that the hose end is in the small beaker and the large beaker is filled with water to the hose outlet
- Take note of the scale reading.
- Slowly raise the lab jack until the acrylic cylinder is completely submerged below the hose.
- Take note of the new scale reading and the volume of overflow water in the small beaker.
- After all water has stopped coming out of the hose, bend the hose and secure it with the clamp.
- Pour the overflow water into the metal bucket to bring the scale back to its initial reading.
