GENERAL EXPLANATION
 
This training device is designed to teach you to determine the center and amount of water pressure acting on an object that is half or full in water.
 
TECHNICAL SPECIFICATION
 
After the weight on the spindle is brought to the balance and the total force is 0, the transparent tank is filled with water and the plastic quadrant is sinked to water in half or full. Equilibrium is added to balance by adding weight. Once the balance is achieved with the help of the knife edge brace, the magnitude of the force, the acting pressure and the central point of the pressure can be found by taking the moment.

Then the water in the tank is drained by the valve.
