Is the Pisa leaning tower experiment real? See how "it" works to validate scientific conjecture

A set of CCTV "Come on! "To the Future" is entertaining, and the deep science knowledge is wrapped in a fun, large-scale experiment that allows children to see fun and excitement.

In the fourth issue, the team’s scientific experiment verification team specially constructed a unique 6-meter-high vacuum tube across the country to challenge the “Leaning Tower of Pisa Experiment”, one of the ten most important scientific experiments of human beings, which is the classic freedom. Fall experiment.

Vacuum Tube Verification of Leaning Pendulum Free Fall Experiment Conjecture

Before the official start of the experiment, with the opening of the Science Gate, the full-scale aerial work platform once again debuted. With it, the experimenter firmly secured a metal ball and a feather on the electromagnet at the top of the vacuum tube. Throughout the entire process, the full-height aerial work platform is able to move forward and backward freely under the operation of the experimenter, and it moves quickly and flexibly and quickly, effectively ensuring the smooth progress of the experiment. The experimental results show that in the same gravitational field, different weight objects fall in the same way.

In fact, in the early stage of the experiment, Dingli Aerial Work Platform has been involved in the manufacture and installation of vacuum tubes. One part of a vacuum tube is two to three hundred kilograms in weight. It is not easy to erect it, let alone the error limit for assembly is in millimeters. If there is even a narrower gap than the hair at each part of the tube, the experiment will not be successful.

Fortunately, there is the help of a full-fledged aerial work platform, and the scientific experiment verification team has been busy assembling it for a whole day. However, this is the first step in the Long March.

Scientific Experimental Verification Team Makes Vacuum Tubes with Full Height Work Platform

In the first test of the second day, the release button was pressed, and the feathers and the ball and the ball fell not so fast! Again! Not as fast! A few days of repeated consultations, discussions, discussions, stay up all night, running around... Each time the test releases feathers and balls, they must operate a full-height aerial platform to raise the top and open the tubes for re-suspension. During the testing process, there were a total of hundreds of experimenters going up and down through the aerial work platform. Hard work pays off, and after continuous exploration and improvement, it achieves almost perfect simultaneous release.

The scientific experiment verification team stated that while being pleased to be able to make such a professional scientific experimental device, it also provided a safe, convenient, and efficient performance point of praise for the experimental good helper.

Since the launch of “Come on to the Future”, Dingli’s Aerial Work Platform has been participating in it, helping both science-loving and science-loving friends in front of the stage and behind the scenes to fall in love with science and science. (This article comes from Zhejiang Dingli)
