Abstract
The utility model discloses a kind of brachistochrone apparatus for demonstrating, this apparatus for demonstrating comprises a base plate and is positioned at the plateau of base plate one end, a linear ramp, a curve slideway, described linear ramp is parallel with one end of curve slideway to be fixed in plateau, the other end is fixed on the end of base plate, the described end at base plate is provided with one and blocks net, and the described end be positioned in plateau at linear ramp and curve slideway is provided with a bare electromagnet.Owing to adopting said structure, demonstration brachistochrone principle that can be directly perceived, true, vivid, makes student understand this physical phenomenon preferably.
Description
Technical field
The utility model relates to a kind of demonstration device, more specifically to a kind of brachistochrone apparatus for demonstrating of education experiment.
Background technology
Chinese patent discloses " a kind of brachistochrone demonstrator ", its structure comprises plateau and slideway, and one end of the slideway of described four different curvatures is fixed on the right side edge of plateau, and one end is fixed on base plate, the angle, two, right side of plateau is provided with two draw-in grooves, and draw-in groove card has baffle plate; Plateau is fixed with four short slideways, four short slideways bottom against baffle plate; Article four, slideway be respectively provided with a sensor bottom, each sensor is connected with a bulb, four short slideways are respectively put a ball, pull-up baffle plate, four balls will tumble on four slideways, are rolled down from slideway, when ball is by slideway sensor bottom, bulb will be lighted, and the bright order of observation lamp bubble point determines which the fastest slideway landing time, thus determines the existence of brachistochrone.Find in demonstration, though this brachistochrone demonstrator can demonstrate the principle of brachistochrone, due to the initial velocity with baffle controls four beads, often cause the mistiming, initial velocity poor synchronization, affects demonstrating effect.
Summary of the invention
It is strong that the purpose of this utility model is to provide a kind of initial velocity synchronism, the brachistochrone apparatus for demonstrating of good demonstration effect.
The purpose of this utility model is achieved through the following technical solutions, this brachistochrone apparatus for demonstrating comprises a base plate and is positioned at the plateau of base plate one end, a linear ramp, a curve slideway, described linear ramp is parallel with one end of curve slideway to be fixed in plateau, the other end is fixed on the end of base plate, the described end at base plate is provided with one and blocks net, and the described end be positioned in plateau at linear ramp and curve slideway is provided with a bare electromagnet.
During lecture experiment, two quality, equirotal bead are inhaled on the bare electromagnet of energising simultaneously, during demonstration, cut off the electricity supply, two beads leave bare electromagnet along the downward landing of respective track simultaneously, and the bead of curve slideway arrives first terminal on the contrary, drops to and blocks in net, this is because the bead on curve track first reaches top speed, so first arrive.
The beneficial effects of the utility model: demonstration brachistochrone principle that can be directly perceived, true, vivid, make student understand this physical phenomenon preferably.
Accompanying drawing explanation
Embodiment of the present utility model is described in detail below in conjunction with accompanying drawing
Fig. 1 is schematic diagram of the present utility model
In figure: 1, base plate 2, plateau 3, linear ramp 4, curve slideway 5, block net 6, bare electromagnet
Embodiment
As shown in Figure 1, this brachistochrone apparatus for demonstrating comprises a base plate 1 and is positioned at plateau 2, linear ramp 3 of base plate 1 one end, a curve slideway 4, linear ramp 3 is parallel with one end of curve slideway 4 to be fixed in plateau 2, the other end is fixed on the end of base plate 1, be provided with one in the end of base plate 1 and block net 5, be provided with a bare electromagnet 6 at linear ramp 3 and curve slideway 4 end be positioned in plateau 2.
