Which of the following is considered a foil shape?

Question

Quizplus · Accepted Answer

A foil shape refers to a shape with a curved surface that is designed to provide lift when moving through a fluid, such as air or water. Both a human hand and a discus can be considered foil shapes, as they have curved surfaces that can provide lift. A shot put, on the other hand, has a rounded shape but does not have a curved surface designed for lift, and therefore is not considered a foil shape.
