Abstract
The utility model belongs to teaching demonstration utensil field, more particularly to a kind of Hooke's law apparatus for demonstrating, can demonstration recklessly can law while show stress and strain between linear relationship.A kind of Hooke's law apparatus for demonstrating, including installing plate, tensiometer, extension spring, scale is set on installing plate to be connected with drawing area, tensiometer with extension spring by cord, extension spring one end is fixed with installing plate, and scale is horizontal positioned with extension spring.By tensiometer and extension spring, scale can relation between presentation material stress and strain, between the two relation area can drawn with real-time rendering, make student more intuitively understand that what is linear relationship.
Description
Technical field
The utility model belongs to teaching demonstration utensil field, more particularly to a kind of Hooke's law apparatus for demonstrating.
Background technology
Hooke's law is very important link as the philosophy in physics teaching in secondary school, in quality-oriented education in order to
It can allow student that the principle of Hooke's law is understood more intuitively to carry out assisted teacher using teaching aid and demonstrated.Hooke's law：
It is linear between the stress and strain (unit deformation amount) in material after solid material stress.Therefore, required teaching aid should
Below the satisfaction some：Stress intensity, material deformation amount and above-mentioned contact between the two.
A kind of Hooke's law experiment demonstrator is disclosed in patent 201520286615.5, applies weight on spring to draw
Long spring, recklessly can law to be demonstrated for student by the gravity of weight and the relation of spring elongation.Although such scheme can be with
Stress and strain is shown, but it is not directly perceived enough for relation performance between the two, it is impossible to embodied by single teaching aid " linear to close
System ".
The content of the invention
A kind of Hooke's law apparatus for demonstrating of the utility model offer, stress can be showed with answering while law recklessly in demonstration
Linear relationship between change, used technical scheme are：
A kind of Hooke's law apparatus for demonstrating, including installing plate, tensiometer, extension spring, scale are set with drawing area on installing plate,
Tensiometer is connected with extension spring by cord, and extension spring one end is fixed with installing plate, and scale is horizontal positioned with extension spring.By tensiometer with
Extension spring, scale can relation between presentation material stress and strain, between the two relation area can drawn with real-time rendering, make student
It is linear relationship that what, which more intuitively understands,.
Preferably, in addition to guide wheel, the guide wheel is set on a mounting board, and cord is by guide wheel by tensiometer and extension spring phase
Contraposition, which installs, to be set to vertically.Tensiometer and extension spring, which are vertically arranged, to be more intuitively converted to indulging in icon by stress and strain
Axle and transverse axis.
Preferably, the extension spring movable end sets mark, and mark matches with scale.Mark is used to refer to extension spring elongation
Length.
Wherein, the drafting area is blank.Blank is convenient to be reused, it is only necessary to which erasing can be demonstrated next time.
Wherein, the drafting area is squared paper, and squared paper is installed on a mounting board by clip.Squared paper is easy to draw song
Line, make the performance of linear relationship between stress and strain more accurate.
Preferably, base is set below installing plate, leg is set below base, leg sets height-adjusting knob.Pass through height
Degree adjusting knob adjustable frames height simultaneously improves base stability.
The utility model is simple in construction, can demonstrate extension spring elongation and suffered pulling force, and conveniently by both above-mentioned records
On drawing, student is made intuitively to understand the content of Hooke's law.
Brief description of the drawings
Fig. 1 is the structural representation of embodiment one；
Fig. 2 is the structural representation of embodiment two；
In figure：1- installing plates, 2- tensiometers, 3- extension springs, 4- scales, 5- draftings area, 6- cords, 7- guide wheels, 8- bases,
31- is marked, 51- clips, 81- height-adjusting knobs.
Embodiment
With reference to the accompanying drawings and examples, specific embodiment of the present utility model is described in further detail.
Embodiment one
As shown in figure 1, a kind of Hooke's law apparatus for demonstrating, including installing plate 1, tensiometer 2, extension spring are set on installing plate 1
3rd, scale 4 is connected with drawing area 5, tensiometer 2 with extension spring 3 by cord 6, and the one end of extension spring 3 is fixed with installing plate 1, and scale 4 is with drawing
Spring 3 is placed in parallel, and has mark 31 in extension spring 3, and mark 31 is corresponding with scale 4.Two guide wheels 7 are set in fixed plate 1, and guide wheel 7 is used
In changing cord 6 direction, tensiometer 2 is arranged to the direction of extension spring 3 by two guide wheels 7 vertical.Drafting area 5 is squared paper,
It is arranged on by shelf 51 on installing plate 1.The lower section of installing plate 1 also includes base 8, and the lower section of base 8 is provided with height-adjusting knob
81 leg, height-adjusting knob 81 threadedly adjust height, improve the stability of base 8.
In demonstration, the mark of original state extension spring 3 is located at the initial position of scale 4, pulls tensiometer 2, and extension spring 3 is drawn
It is long, now scale 4 and the reading of tensiometer 2 are write down, is drawing the described point of area 5.Tensiometer 2 is pulled on, is continued according to as above method
Described point, most all points are linked to be lines at last.
Embodiment two
As shown in Fig. 2 it is blank to draw area 5, remainder and embodiment one are essentially identical.
Claims (6)
