China Wholesale Liquid Surface Tension Factories – LMEC-17 Uphill Roller Experiment (Energy conservation) – Labor

Experiments
1. Learn to use vernier caliper, screw micrometer and other related measurement;
2. The physical phenomenon of double cone rolling from low to high was observed from the surface and visual effect;
3. Master the law of conservation of mechanical energy, clear cone rolling is the principle of potential energy into kinetic energy
Total energy conservation;
4. Verify the experimental conditions of cone roll up; When the cone is designed and calculated to meet the condition of up rolling, the guide
The angle of the rail opening, the descent height of the rolling end relative to the end of the rail and the plane inclination of the cone rail are related to each other, then assemble and observe the experimental phenomena;
Main technical features
1. Miniaturization: the base area of the cone up rolling tester is only 32 × The length of guide rail is only 44cm
about;
2. Detachability: all links of the tester can be disassembled;
3. Strong three-dimensional adjustability: the angle between the two tracks of the cone can be adjusted, the inclination angle of the track plane can be adjusted, and the
Different sizes of cones (diameter and height) were selected for experiments;
4. Design experiment: according to the known parameters, the relevant parameters can be calculated by necessary calculation;
5. Comprehensive experiments: both qualitative and quantitative verification of cone rolling experimental conditions.
