Abstract
The utility model discloses a multi-functional single pendulum experiment device which consists of a bottom plate and a frame arranged on the bottom plate. A level device is arranged on the bottom plate; the middle of the top of the frame is provided with a short log crosspiece which is provided with a plurality of small holes and corresponding hole plugs respectively used for fixing single pendulum lines, the lower ends of the single pendulum lines are respectively hung with pendulum balls that are respectively a small iron ball single pendulum, an iron ball single pendulum, a graph drawing single pendulum, a plastic ball single pendulum and another iron ball single pendulum. A painting brush is arranged on the graph drawing single pendulum. A round arc panel is positioned on the bottom plate and below the pendulum balls; the middle part and the lower part of the edges of the frame are respectively provided with an angle iron shape iron sheet and a small magnet; hanging hooks are positioned at the edges of the frame. The utility model is also provided with a pointer-shaped force analyzer and a K-shaped force analyzer matched and arranged for the short-line iron ball single pendulum. The utility model is suitable for the experiments of students and suitable for a demonstration experiment.
Description
Technical field
The utility model relates to a kind of physical experiment apparatus, especially relates to a kind of single pendulum experimenter of using more.
Background technology
In first chapter 9 of the physics of full-time senior middle school textbook the 4th joint---single pendulum, when analyzing the swing ball stressing conditions, the analysis of drawing, both time-consuming, bother again.When putting the vibrational diagram of experimental demonstration single pendulum with sand, troublesome poeration, wayward, effect is also undesirable.Will the survey time in the experiment such as tautochronism of demonstration single pendulum etc., also time-consuming.
Summary of the invention
The utility model is the shortcoming that exists at above-mentioned single pendulum, and a kind of single pendulum experimenter of using is provided more.
The utility model is to use single pendulum experimenter more, and for achieving the above object, the utility model has mainly adopted following technical scheme.This tester is made up of base plate and the framework be located on the base plate, base plate is provided with horizon equipment, the centre at the top of framework is provided with short wooden horizontal cleat, short wooden horizontal cleat is provided with some apertures, and be provided with corresponding stopple, be respectively applied for fixedly single pendulum line, the lower end of single pendulum line hangs with swing ball respectively, and these swing balls are respectively little iron ball single pendulum, short-term iron ball single pendulum, long line iron ball single pendulum, picture single pendulum and baton round single pendulum.On picture single pendulum ball, be provided with paintbrush.On base plate, below swing ball, be provided with the garden curved panel, the middle part on the limit of framework and bottom are respectively equipped with angle bar shape iron sheet and little magnetite, also are provided with hook on the limit of framework.The utility model also is provided with and is the pointer shape force analysis device of the supporting setting of short-term iron ball single pendulum and K font force analysis device.
The utility model compared with prior art.Have following obvious advantage and progress.(1), can demonstrate the single pendulum force analysis, save the trouble of picture, improve the effect of classroom instruction; (2), the vibrational diagram of the single pendulum that can directly draw, simpler and more direct, flexible than the sand pendulum, experiment effect is better; (3), can demonstrate the tautochronism of single pendulum, the demonstration pendulum length and the relation in cycle, the relation of the cycle of pendulum and swing ball quality; (4), can demonstrate a plurality of experiment with simple pendulum, several pendulum can move together, need not survey the time, just can draw experiment conclusion with observing; (5), the cycloid top do not have toe-in, can regulate pendulum length easily, makes experimental data more accurate; (6), Instrument structure is simple, convenient experimental operation; (7), analyzing swing ball when stressed, the equilibrium position represents that with pointer shape force analysis device P point position is represented with K shape force analysis device; (8), be the good teaching material of quality teaching, can cultivate students'creative thinking.
The utility model is applicable to that the student does experiment usefulness, also is applicable to lecture experiment.
Description of drawings
Accompanying drawing is the utility model one-piece construction figure.
