Everyone knows that horses have great pulling power. A good horse weighing 0.7 tons can pull up to 3.5 tons of goods on a four-wheeled vehicle on a good road surface, which is equivalent to 5 times its own weight.
You may not have thought that the strongest drag force among animals is not a horse, but a six-legged insect. Of course, what we are talking about here is relative pulling force, not absolute numbers. In absolute terms, of course, more weight means more power.
In order to prove how powerful the pulling force of insects is, someone once conducted an experiment: a large earwig weighing only 0.5 grams, commonly known as the ear clip insect, was tied to a clip at the tail with a thread and placed on a smooth ground. , can drag a 170-gram empty toy car to crawl forward quickly. Later, the empty car was loaded with things, and the weight gradually increased to 265 grams, which can still be barely towed. If you take the weight of the earpin worm, subtract the total weight it drags, and then round up the result, you can get an astonishing number. The weight it drags is equivalent to 500 times its own weight.
