Question

Quizplus · Accepted Answer

The Falkirk Wheel is designed in such a way that the opposite caissons are precisely balanced, regardless of the weights of any boats in them, or even if they are empty. This means that the Wheel can rotate smoothly and efficiently, using the same amount of energy to lift one caisson as it does to lower the other. Choice A is incorrect because while the boats in each caisson may be roughly equal in weight, this is not a key feature of the Wheel itself. Choice B is also incorrect, as it is not necessary for at least one boat to be in each caisson for the Wheel to function properly.
