Description
Technical field
The utility model is related to teaching aid technical field, the synthesis decomposition experiment apparatus for demonstrating of especially a kind of power.
Background technology
The synthesis of power and the important knowledge point that decomposition is in Middle School Physics, this course knowwhy is more abstract, Xue Shengnan
To understand and master, when teaching, usually requires to carry out experiment to carry out demonstration aided education, to facilitate student to be better understood from study, shows
Some experiments are tested usually using meter, rubber item, cord, blank sheet of paper, plank, and experimental implementation is cumbersome, can only be simple
The synthesis and decomposition of power are demonstrated, error is larger, cannot accurately be calculated, teaching efficiency is bad.
Invention content
The purpose of this utility model is to overcome above-mentioned technical disadvantages to provide a kind of synthesis decomposition experiment demonstration dress of power
It sets.Easy to use, flexible adjustment, DATA REASONING is accurate, can be tested by proper orthogonal decomposition according to experimental demonstration data
Contrast verification is calculated, facilitates student to understand and master course knowwhy point, improves teaching demonstration effect.
The utility model solve the technical solution that uses of technical problem for：A kind of synthesis decomposition experiment apparatus for demonstrating of power,
Including pedestal, experimental plate, fixed pulley, counterweight, protractor, the pedestal both sides are symmetrically fixed with perpendicular supporting rod,
Supporting bar top is fixed with the experimental plate of semicircular irony, and experimental plate both sides are symmetrically hingedly fixed with 2 by hinged shaft and determined
Pulley, the span on 2 fixed pulleys have pulling rope, and fake is cased on the pulling rope between 2 fixed pulleys, is fixed on the downside of fake
Resultant force is restricted, and pulling rope both ends and resultant force rope lower end are respectively and fixedly provided with appending disk, counterweight are placed in appending disk, the protractor is by angle
It spends plate, line plate, magnetic sheet is formed, it is perpendicular rectangular to line plate that angle board is that its semicircle downside is equipped with, angle board
The back side is inlaid with semicircular magnetic sheet and is adsorbed on experimental plate, is equipped with cross hair, angle on the downside of angle board at edges of boards center
It is equipped with using cross hair intersection point as the angle line in the center of circle at the edges of boards of plate.When experiment, equivalent weight can be put in 3 appending disks
Counterweight, then adjust protractor position, so that pulling rope and the intersection point of the intersection point of fake and cross hair is overlapped, and make cross
Vertical line is restricted with resultant force and is overlapped on the downside of line, then reads the angle of fake both sides pulling rope and calculated, and is adjusted again after having been calculated
Fake position carries out demonstration and verification by above-mentioned experimental procedure；Also the weight such as not can be put when experiment in 3 appending disks
Then counterweight uses protractor to measure related angle and carries out experimental calculation contrast verification by proper orthogonal decomposition, experimental implementation is simple,
Flexible adjustment, DATA REASONING is accurate, can carry out experimental calculation contrast verification by proper orthogonal decomposition according to experimental demonstration data, convenient
Student understands and masters course knowwhy point, improves teaching demonstration effect.
Advantageous effect possessed by the utility model is：The structure design of the utility model is reasonable, easy to use, adjusts
Flexibly, DATA REASONING is accurate, can carry out experimental calculation contrast verification by proper orthogonal decomposition according to experimental demonstration data, facilitate student
Course knowwhy point is understood and mastered, teaching demonstration effect is improved.
Description of the drawings
Attached drawing 1 is the structural schematic diagram of the utility model.
Specific implementation mode
1 pair of the utility model is described below below in conjunction with the accompanying drawings.
As shown in Figure 1, the utility model includes pedestal 1, experimental plate 3, fixed pulley 5, counterweight 8, protractor, the pedestal 1
Both sides are symmetrically fixed with perpendicular supporting rod 2, and 2 top of supporting rod is fixed with the experimental plate 3 of semicircular irony, real
Testing the span that 3 both sides of plate are symmetrically hingedly fixed with by hinged shaft 4 on 2 fixed pulleys, 5,2 fixed pulleys 5 has pulling rope 6,2 fixed
Fake 10 is cased on pulling rope 6 between pulley 5,10 downside of fake is fixed with resultant force rope 9,6 both ends of pulling rope and resultant force rope 9
Lower end is respectively and fixedly provided with appending disk 7, is placed with counterweight 8 in appending disk 7, the protractor by angle board 11, to 15 groups of line plate 12, magnetic sheet
It is perpendicular rectangular to line plate 12 to be that its semicircle downside is equipped at, angle board 11, the back side of angle board 11 is inlaid with half
Circular magnetic sheet 15 is simultaneously adsorbed on experimental plate 3, and cross hair 13 is equipped at 11 downside edges of boards center of angle board, angle board 11
It is equipped with using 13 intersection point of cross hair as the angle line 14 in the center of circle at edges of boards.When experiment, same weight can be put in 3 appending disks 7
Then the counterweight 8 of amount adjusts protractor position, pulling rope 6 and the intersection point of the intersection point of fake 10 and cross hair 13 is made to overlap, and
So that 13 downside vertical line of cross hair 9 is overlapped with resultant force rope, then read the angle of 10 both sides pulling rope 6 of fake and calculated,
10 position of fake is adjusted after having been calculated again, demonstration and verification is carried out by above-mentioned experimental procedure；It also can be in 3 appending disks when experiment
The counterweight 8 of the weight such as not is put in 7, is then used protractor to measure related angle and is carried out experimental calculation comparison by proper orthogonal decomposition
Verification, experimental implementation is simple, and flexible adjustment, DATA REASONING is accurate, can be carried out in fact by proper orthogonal decomposition according to experimental demonstration data
Calculating contrast verification is tested, facilitates student to understand and master course knowwhy point, improves teaching demonstration effect.
