Device for studying inertial forces, consists of a platform (2) whereon are latrally set wheels (1). On the platform (2) from the top transversally and firmly set is a frame (8) onto which are from the top fixed a cell (12) and symmetrically two electric motors (10) with regulators (11) for adjusting number of revolvements. On the shafts (9) of the electric motor (10) are fixed the pipes (6), that are from the bottom side in the same axis by means of the pins (4) set in the platform (2), thus the pipes (6) may revolve in horisontal plane. The pipes (6) are along the middle separated, and in them are from the both sides set the globes (3) diameter of which is shorter than the internal diameter of the pipe (6). On the platform (2) by means of the screws (13) are fixed the holders (5) whereon are firmly fixed the rings (7) that go through horisontal crosssections set on both sides of the pipe (6), where adjusting of the distance of the center among the rings (7) is allowed in relation to the axis of the electric motor (10), i.e. center of rotation of the pipe (6). Along with the idea of the invention, by means of a regulator (11) it is possible to change the speed and directions of rotation of the pipe (6), and by the screw (13) to alter the size of rotation eccenter of the globes (3) in relation to the center of rotation of the pipe (6), as the path of the globes (3) is defined by the internal circumference of the ring (7). As the size of the centrifugal force of the globes (6) depends on the radius of rotation and speed of angle, thus it is allowed to adjust the speed and direction of motion of the wheels. |
