1.3 Explain and apply Archimedes Principle to engineering problems.

1. Explain Archimedes' principle.

2. Explain why objects with a specific gravity of less than one will

float in water.

3. A spherical buoy of diameter 0.3 m and mass 4.2 kg is attached

to the seabed by a mooring rope and floats fully submerged.

Calculate the tension in the mooring rope. The density of the

seawater is 1025 kgm.
