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.
