Abstract
The utility model discloses a do critical problem lecture experiment device of circular motion bobble through pipe peak includes base (1), support (2), track (3), transparent pipe (4), bobble (5) at least, and install on base (1) support (2), track (3) are fixed on support (2), track (3) by one section straight track of slope and with it tangent convex between tracks connection form, the inboard in track (3) is placed and fixed in transparent pipe (4) along the inboard of track (3) to being located vertical incision the in transparent pipe (4) of track (3) slope on straight, get rid of transparent pipe (4) by vertical the first half of openning, bobble (5) slightly are less than the steel ball of pipe internal diameter for the diameter. Release different positions through the transparent pipe of control bobble on the track slope is straight, and messenger's bobble moves along transparent pipe and do the close zero that is of speed that circular motion crossed the peak in vertical face, also is exactly the circumstances that can cross the peak just.
Description
Technical field
The utility model relates to a kind of teaching equipment, the experimental demonstration that the critical problem being specifically applicable to move in a circle little ball warp pipe peak is analyzed.
Background technology
In senior middle school physics teaching, about the analysis of the critical problem of the little ball warp pipe peak that moves in a circle, the demonstrating experiment device that laboratory is not ready-made.Laboratory only has similar experiment equipment, as centrifugal railway model.Pressure to bead when bead can be provided inside the track of centrifugal railway to move in a circle in vertical plane along track; And the pipe not only pressure of outside tube wall to bead when bead can be provided to move in a circle in vertical plane along pipe, and the holding power to bead when inner side tube wall can also provide bead to move in a circle in vertical plane along pipe.Therefore, the critical velocity through peak when the critical velocity of peak and bead move in a circle in vertical plane along pipe when bead moves in a circle in vertical plane along track is different.And middle school is said from birth, the critical velocity through peak when why bead moves in a circle in vertical plane along pipe is zero, is but very elusive.If there is an experimental provision can demonstrate this problem preferably, highly beneficial student is understood this problem.
Utility model content
The purpose of this utility model is the experimental provision that making one is new, provides a kind of critical problem analysis design mothod apparatus for demonstrating demonstrating the little ball warp pipe peak that moves in a circle well.
For achieving the above object, the critical problem demonstrating experiment device of the little ball warp pipe peak that moves in a circle that the utility model proposes, its structure comprises: base, support, track, transparent round tube, bead, and described support installing is on base; Described track is fixed on support, and track is formed by connecting by one section of inclination straight track and arc-shaped rail tangent with it; Described transparent round tube is placed along the inner side of track and is fixed on the inner side of track, and be positioned at track inclination straight on transparent round tube longitudinally cut, remove transparent round tube by the upper part longitudinally cut; Described bead is the steel ball that diameter is slightly less than round tube inside diameter.
The utility model compared to existing technologies, have the following advantages: by controlling the diverse location release of the transparent round tube of bead on track inclination is straight, the speed making bead move across in vertical plane along transparent round tube the peak that moved in a circle is close to zero, and namely just can cross the situation of peak.
Accompanying drawing explanation
Accompanying drawing is the structural representation that the utility model executes example.
1: base; 2: support; 3: track; 4: transparent round tube; 5: bead.
Embodiment
The critical problem demonstrating experiment device of the little ball warp pipe peak that moves in a circle that the utility model proposes, its structure comprises: base 1, support 2, track 3, transparent round tube 4, bead 5, and described support 2 is arranged on base 1; Described track 3 is fixed on support 2, and track 3 is formed by connecting by one section of inclination straight track and arc-shaped rail tangent with it; Described transparent round tube 4 is placed along the inner side of track 3 and is fixed on the inner side of track 3, and be positioned at track 3 tilt straight on transparent round tube 4 longitudinally cut, remove transparent round tube 4 by the upper part longitudinally cut; Described bead 5 is slightly less than the steel ball of round tube inside diameter for diameter.
Using method of the present utility model:
By controlling the diverse location release of the transparent round tube of bead on track inclination is straight, the speed making bead move across in vertical plane along transparent round tube the peak that moved in a circle is close to zero, and namely just can cross the situation of peak.
By above-mentioned experiment, student can observe bead well can with the speed close to zero through the highest situation, and the critical velocity also just well understanding the little ball warp pipe peak that moves in a circle is the problem of zero.
