In this study, we propose a high ratio involute gear reducer using the Vernier effect, so-called Vernier drive. Our design consists of a fixed internal gear, a rotating internal gear, and single-profile planetary gears, which are mounted on a carrier

We investigate experimentally the free-fall motion of a pair of identical disks rigidly connected to each other. The three-dimensional coordinates of the pair of falling disks were constructed to quantitatively describe its trajectory, and the flow s
