¿Qué dos condiciones se tienen que dar para que una embarcación esté en equilibrio?What two conditions must be met for a boat to be in equilibrium?
Show the answer
Correct answer: a) Displacement must equal buoyancy, and the centre of gravity must be on the same vertical as the centre of buoyancy.
Why it is correct
Weight and buoyancy must be equal and act on the same vertical, so the boat neither sinks nor turns.
Why the others are not
- b) With less weight than buoyancy, the boat would rise.
- c) Unequal forces on different verticals would move the boat.
- d) With more weight than buoyancy, the boat would sink.
How to work it out in the exam
- Two conditions: equal forces and same vertical.
