摘要

1. Device for demonstrating the laws of mechanics, comprising a guide provided with height adjustable legs at the ends and barriers platform arranged on the guide movable along it, the actuator moving platforms measuring system comprising a projection screen and elektrosekundomer, characterized in that the guide is in the form of two parallel rails, moreover, the number of platforms and more than two, they are provided with rollers, wherein one of the platforms is formed a self-propelled, the first of the non-self platform provided with a removable hook, fixed at one of its ends, and a buffer designed as a spring and is detachably fixed to the end of the same end of the platform, and the second non self-propelled platform is provided with a removable hook mounted to cooperate with a hook of the first platform, all platform provided with nodes for fixing to them of measuring complex devices, which includes a chronograph accelerometers maximum effect dynamometer disc preferably furthermore the kit comprises cargo-set weighting and detachable screen, whose length corresponds to the length of the self-propelled platform, moreover, the demonstration screen is formed as a vertically disposed strips, provided with supports, whose length corresponds to the length of the working napravlyayuschey.2.
