China Wholesale Cavendish Balance Factory – LMEC-13 Comprehensive Experiments on Rotating Liquid – Labor
China Wholesale Cavendish Balance Factory – LMEC-13 Comprehensive Experiments on Rotating Liquid – Labor Detail:
Rotating liquid laboratory is a classic and modern experiment. As early as the foundation of mechanics, there was Newton’s bucket experiment. When the water in the bucket rotates, the water will rise along the wall of the bucket. Until now, there are still rotating liquid experiments in some foreign universities. Fd-rle-a rotary liquid comprehensive experimental instrument uses semiconductor laser to detect the liquid surface dip angle and Hall sensor to detect the rotation period, and reproduces the rotary liquid experiment in the way of modern teaching experiment.
Experiments
1. Measure gravity acceleration g using two methods:
a) measure the height difference between the highest and the lowest points of the surface of rotating liquid, then calculate gravity acceleration g;
b) laser beam incident parallel to the rotation axis to measure surface slope, then calculate gravity acceleration g;
2. Verify the relationship between focal length f and rotational period T according to the parabolic equation;
3. Study concave mirror imaging of rotating liquid surface.
