Specific embodiment
For the content of the invention of the present utility model, feature and effect can be further appreciated that, following examples are hereby enumerated, and is coordinated
Accompanying drawing describes in detail as follows：
Refer to Fig. 1 and Fig. 2, a kind of mechanics comprehensive demonstrator, including comprehensive support 1 and for can be positioned over upper rail 4,
Free skewback 3 and dolly 2 on middle orbit 7 and lower railway 10, the upper rail 4, middle orbit 7 and lower railway 10 are respectively arranged at
On the comprehensive support 1, the front of the upper rail 4 is provided with the 3 upper labelling balls 16 fixed by upper fixing screws 15, middle rail
What the front in road 5 was provided with the middle labelling ball 13 fixed by middle fixing screws 13 and two ends is respectively equipped with fixed pulley 4, described to determine cunning
Wheel 4 is installed on the comprehensive support 1 by fixing axle 19, and the light scraps of paper 5 are provided with the middle orbit 7, the light scraps of paper 5
Two ends are respectively arranged with fine rule 8, and the end of the fine rule 8 is provided with hook code 9, and the fine rule is across the fixed pulley 6, the lower rail
The front in road 10 is provided with the lower labelling ball 12 fixed by lower fixing screws 11, is provided with vertical position in the side of comprehensive support 1
Screw 17 and horizontal level screw 18.
This utility model independently can be put on the table, and the experiment that can be completed has：
(1) probe into impact of the resistance to object of which movement
Towel face is spread on the upper rail 4 of comprehensive support 1, cotton face on middle orbit 7, is spread, lower railway 10 is plank
Face, allows free skewback 3 to be individually placed on these three tracks, then allows dolly 2 freely to glide from the top of free skewback 3, observation
The position that dolly finally stops, recording the distance that dolly is slided by the labelling ball on track.
