Abstract
The invention discloses a simple-pendulum pendulum ball control device, which mainly comprises a pedestal, an electromagnet, a snakelike hose, a switch, wires and a power supply, wherein the snakelike hose is connected to the pedestal; the electromagnet is fixed at the upper end of the snakelike hose; and the electromagnet, the switch and the power supply are connected together by using two wires. When the device is used, the pedestal is arranged at the edge of an experiment table, and the power switch is turned on, so that the electromagnet attracts a simple-pendulum pendulum ball; and the pedestal and the snakelike hose are adjusted, so that the simple-pendulum pendulum ball is kept at a proper initial position; the switch is turned off, so that the pendulum ball starts to swing, and swing period can be measured regularly after the pendulum ball swings stably. The device has the advantage of preventing elliptic conical pendulum motion of the pendulum ball.
Description
Technical field
Type of the present invention is applied to the control of experiment with simple pendulum swing ball.
Background technology
When doing experiment with simple pendulum now, the initial position of swing ball is held with palm by the experimenter, be difficult to guarantee that swing ball center of gravity and cycloid were in perpendicular of cycloid hitch point simultaneously, thereby swing usually has elliptic motion, form oval conical pendulm, experimental implementation and measurement are caused adverse effect.
Summary of the invention
In order to overcome oval conical pendulm experimental implementation and measurement are caused adverse effect, type of the present invention has designed a kind of single pendulum swing ball control device, can avoid the elliptic cone pendular motion of single pendulum swing ball effectively.
The elliptic cone pendular motion that type of the present invention solves because of the single pendulum swing ball causes the technical scheme of adverse effect to be to experimental implementation and measurement, fix the position in advance with an electromagnet, mixing up cuts off the power supply behind the initial position of single pendulum swing ball gets final product, described single pendulum swing ball control device mainly is made up of rectangular seat, electromagnet, snake-like hose, switch, lead and power pack, snake-like hose is connected on the rectangular seat, electromagnet is fixed on the snake-like hose upper end, and two leads couple together electromagnet, switch and power supply.During use, rectangular seat is placed the edge of laboratory table, the energized switch, make electromagnet hold the single pendulum swing ball, regulate snake-like hose, make the single pendulum swing ball be in suitable initial position, cut-off switch, swing ball begin swing, observe the swing ball swinging track, if any the elliptic cone pendular motion, then need further to adjust the position of snake-like hose and electromagnet, there is not the elliptic cone pendular motion up to swing ball, and swing steadily the back just can timing measuring hunting period, in the time of need repeatedly measuring, as long as the energized switch, electromagnet holds behind the swing ball outage again and just can measure once more.After changing cycloid length or pendulum angle, readjust snake-like hose and electromagnet position, make swing ball be in new initial position and can carry out subsequent experimental, if cycloid is very long, when swing ball moved below desktop, it is following so that the fixing initial position of swing ball that snake-like hose can bend to desktop.
The advantage of type of the present invention is by the suction-operated of electromagnet swing ball is begun a fixing position, has prevented the generation of oval conical pendulm thus.
Description of drawings
Below in conjunction with drawings and Examples type of the present invention is described further.
Fig. 1 is the structural principle and the embodiment synoptic diagram of type of the present invention.
Among the figure, 1, rectangular seat, 2, electromagnet, 3, snake-like hose, 4, switch, 5, power supply, 6, lead.
Embodiment
In the drawings, rectangular seat (1) material is an iron, weigh 5 kilograms, good stability, snake-like hose (3) both can be crooked, has sufficient intensity again, and snake-like hose (3) is connected on the rectangular seat (1), electromagnet (2) is fixed on the upper end of snake-like hose (3), and lead (6) connects electromagnet (2), switch (4) and power pack (5).
Claims (3)
1. single pendulum swing ball control device, it is characterized in that described device mainly is made up of rectangular seat, electromagnet, snake-like hose, switch, lead and power pack, snake-like hose is connected on the base, and electromagnet is fixed on the snake-like hose upper end, and two leads couple together electromagnet, switch and power supply.
2. single pendulum swing ball control device according to claim 1 is characterized in that base weighs 5 kilograms.
3. single pendulum swing ball control device according to claim 1 is characterized in that snake-like hose can bend to the desktop initial position of each swing ball up and down.
