Abstract
The utility model discloses a multifunctional Archimedes principle teaching instrument including a pedestal, a support, a water cup, a measuring glass, a weight, a spring-loaded thrust meter, a table-type dynamometer, a cord, a fixed pulley, a worm gear, a worm and a rocking bar. The pedestal is fixed with the support together. A side of the pedestal is provided with a boss. The water cup is disposed on the boss. The upper part of the water cup is provided with a water pipe. The table-type dynamometer is disposed beside the boss. The measuring glass is disposed on the table-type dynamometer. The opening of the measuring glass is below the water pipe. The body of the measuring glass is provided with scales and is marked with volume. The upper part of the support is provided with the fixed pulley. The fixed pulley is disposed exactly above the water cup. A side of the support is provided with a worm and gear mechanism composed of the worm gear and the worm. The worm is connected with the rocking bar fixedly. One end of the cord is coiled on a worm gear shaft while the other end is connected with the tail end of the spring-loaded thrust meter after winding around the fixed pulley. The weight is hanged on a hook of the spring-loaded thrust meter. The multifunctional Archimedes principle teaching instrument is convenient to manufacture and operate, low in cost and direct in display and facilitates understanding, memorizing and re-innovation of students.
Description
Technical field
The utility model belongs to junior middle school physics teaching equipment, relates to a kind of multi-functional Archimedes principle teaching appliance.
Background technology
In junior middle school physics teaching process, there is the teaching demonstration experiment of an Archimedes' principle.Archimedes' principle is a ultimate principle of mechanics in physics.Specifically being expressed as of it: be immersed in the gravity that the size of making a concerted effort that object in stationary fluid is subject to fluid effect equals the fluid that object arranges, this makes a concerted effort to be called buoyancy.
Floating=G row=ρ liquid gV discharge opeing that its formula can be designated as F.
In existing instruments used for education, be mainly to utilize weight beam, iron block and a water tumbler etc. to test.In order to make student understand in detail Archimedes' principle, in experimentation, need to be to experiment several times, multi-step demonstration and calculating, be unfavorable for teaching efficiency.
Utility model content
Multi-functional Archimedes principle teaching appliance is comprised of base, support, spilling water cup, measuring cup, weight, weight beam, desk-top dynamometer, cord, fixed pulley, worm gear, worm screw and rocking bar.
Base and support are fixed, and base one side is provided with boss, places spilling water cup on boss, spilling water cup top is provided with overflow pipe, and desk-top dynamometer is placed on boss side, on desk-top dynamometer, places measuring cup, measuring cup opening, below overflow pipe, has rule on measuring cup cup, and indicates volume.Support top is provided with fixed pulley, fixed pulley be positioned at spilling water cup directly over, support one side is provided with the worm-and-wheel gear being comprised of worm gear and worm screw, worm screw is fixedly connected with rocking bar.One end of cord is wrapped on worm-wheel shaft, and the other end is walked around fixed pulley and is connected with weight beam tail end, and weight hangs in the hook of weight beam.
The utility model is used a worm-and-wheel gear.Worm-and-wheel gear has auto-lock function, and it can make weight rest on allowed band Nei optional position, and can realize stepless control.
The utility model is used a cup to be provided with rule and indicates the measuring cup of volume, can measure easily the volume of water.
The utility model has the advantage of simple in structurely, make and easy to operate, cost is low; By weight beam and desk-top dynamometer, weigh simultaneously and record volume with measuring cup and carry out experimental demonstration, vividly directly perceived, contribute to student understand, remember and innovate again.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Wherein: the 1st, base, the 2nd, spilling water cup, the 3rd, support, the 4th, weight, the 5th, weight beam, the 6th, cord,
The 7th, fixed pulley, the 8th, worm gear, the 9th, worm screw, the 10th, rocking bar, the 11st, measuring cup, the 12nd, desk-top dynamometer.
Embodiment
Shown in Fig. 1, use novel Archimedes principle teaching appliance to carry out experimental demonstration process as follows:
The first step, to water filling in spilling water cup, makes the water surface concordant with overflow pipe entrance extreme lower position;
Second step, the reading F1 while reading weight beam carry weight, reads desk-top ergographic reading F2 under measuring cup anhydrous state;
The 3rd step, shakes rocking bar, and weight is declined, and after weight is immersed in the water, water flows into measuring cup by overflow pipe.
Now can stop shaking, read respectively the reading V1 of the reading F3 of weight beam, desk-top ergographic reading F4 and measuring cup, by calculating:
Float=F1-F3 G row=F4-F2 of F
F1－F3＝F4－F2
Can release: float=G of F row.That is: be immersed in object in stationary fluid and be subject to the gravity that buoyancy in fluid equals the fluid that object arranges.And show that now the water discharge of weight is V1.
The 4th step, continues to shake rocking bar, demonstrates when different immersion amounts the correctness of Archimedes' principle.
Finally, after weight is immersed in the water completely, the correctness of demonstration Archimedes' principle.Now, can also read the reading V2 of measuring cup, by calculating the average density that can draw weight:
ρ＝F1／(g·V2)
Here it is, and two thousand years front great Ancient Greece man, mathematician, physicist, mechanics scientist, static mechanical and fluidstatic founder Archimedes measure the principle of imperial crown volume and density with drainage.
Be not difficult to find out, multi-functional Archimedes principle teaching appliance can be verified Archimedes' principle, survey volume and the density of irregular solid.In addition, student can utilize the utility model to carry out other Physical Experiment, also can and design on this basis better more practical experimental apparatus with reference to the utility model.
