Abstract

Изобретение относитс к учебным приборам по механике и позвол ет повысить нагл дность демонстрации процессов сложени сил т готени и центробежных сил инерции. Прибор содержит вертикально размещенный на основании 1 корпус 2, установленную в корпусе на оси 3 вращени лицевую панель а виде диска 4, на котором установлены два блока 5, 6, свободно установленные на оси вращени два рычага 7, 8 с закрепленными на них грузами 9 и 10, св занные гибкой т гой 11, переброшенной через блоки, средство регистрации перемещени грузов и привод вращени оси, причем в каждом грузе выполнена полость 13. Средство регистрации состоит из размещенных в полости каждого груза лентопрот жного механизма 14 с бумажной подложкой 15, источника питани и пишущего элемента 16, закрепленного на диске. При вращении диска 4 груз, наход щийс в нижней его точке, под действием на него силы т готени замедл ет свое движение, вследствие чего нат гивает гибкую т гу 11, а груз, размещенный в верхней точке диска, находитс в состо нии свободного падени , близкому к состо нию невесомости, вследствие него его воздействие на т гу 11 осла- бевает и оба рычага 7,8 несколько смещаютс от первоначального положени , соверша таким образом колебательные движени , которые записываютс на подложке 15. 3 ил. со СThe invention relates to educational devices in mechanics and makes it possible to increase the consistency of the demonstration of the processes of combining gravitational forces and centrifugal inertial forces. The device contains a housing 2 vertically placed on the base 1, a front panel mounted in the housing on the axis of rotation 3, and in the form of a disk 4 on which two blocks 5, 6 are installed, two levers 7, 8 freely mounted on the axis of rotation with loads 9 attached to them 10, coupled with a flexible pull 11 transferred through the blocks, means for detecting the movement of goods and driving the axis of rotation, and a cavity 13 is made in each load. The means of recording consists of a tape-moving mechanism 14 placed in the cavity of each load 15, a power source and writing element 16, fixed to the disk. When the disk 4 rotates, the load, which is at its lower point, under the action of a puffing force on it slows down its movement, as a result of which it pulls a flexible pull 11, and the load placed at the top point of the disk is in a free fall state, close to the state of weightlessness, as a result of which its effect on the thru 11 weakens and both levers 7.8 move somewhat from the initial position, thus performing oscillatory movements, which are recorded on the substrate 15. 3 Il. with C

Claims

Claim

A training device in mechanics, comprising a housing vertically placed on the base, two levers mounted on the housing on the axis of rotation, with weights fixed at their ends, one of which is connected to the axis of rotation by a flexible rod, and an axis rotation drive, characterized in that, in order to increase For clarity, it is equipped with a means of recording the movement of goods, consisting of a tape drive with a paper substrate, a power source and a writing element, and a front panel placed behind the levers in the form of a disk mounted on the axis of rotation. on the periphery of which two blocks are diametrically opposed, the flexible rod is thrown through the blocks and connected with the second lever with its free end, and in each load there is a cavity in which the tape drive mechanism is placed, while the levers are freely mounted on the axis of rotation, and the writing element is fixed to drive.
