The Double Cone: A Mechanical Paradox or a Geometrical Constraint?
Gallitto, Aurelio Agliolo; Fiordilino, Emilio
Physics Education, v46 n6 p682-684 Nov 2011
In the framework of the Italian National Plan "Lauree Scientifiche" (PLS) in collaboration with secondary schools, we have investigated the mechanical paradox of the double cone. We have calculated the geometric condition for obtaining an upward movement. Based on this result, we have built a mechanical model with a double cone made of aluminum and a couple of wooden rails. (Contains 2 figures.)
