Speaking of the wooden cow and the flowing horse, everyone must think that this is a "perpetual motion machine". The principle does not make sense, so it must be made up by "The Romance of the Three Kingdoms".
But in fact, "wooden ox and flowing horse" actually existed and was written into the official history "Three Kingdoms".
During Zhuge Liang's Northern Expedition from the ninth to the twelfth year of Jianxing, wooden oxen and flowing horses were widely used to escort grain and grass in the Shu Han Dynasty. Each wooden oxen and flowing horses could carry four hundred kilograms of grain and travel dozens of miles a day.
It is recorded in "The Chronicles of the Three Kingdoms? The Chronicles of Shu? The Biography of Zhuge Liang": Brightness is better than ingenuity, profits and losses are continuous, and the wooden ox and the horse are all out of his mind. ?
It can be seen that Zhuge Liang has the invention patent for this magical object.
Concerning the use of wooden oxen and horses, "The Chronicle of the Three Kingdoms: Zhuge Liang's Biography" records: In the ninth year of Jianxing, Liang returned to Qishan and used wooden oxen to transport the food and retreated the army; Coming out of the valley, he used flowing horses to move to Wugong Wuzhangyuan, and fought against Weinan with King Xuan of Sima. ?
Having said so much, is it feasible? Minglion's answer is: It's feasible, but it's not as magical as Jinri in the novel.
In fact, the wooden ox and the flowing horse are Zhuge Liang's labor-saving wheeled transportation tools made by using principles such as bearings.
In fact, it is more sophisticated than the current wooden wheel vehicle, but it is still a means of transportation within the category of rickshaw.
Actually, there are many people who share this view with me. For example, Chen Shidao of the Northern Song Dynasty left a passage: There is a small cart in Shu, which can carry eight stones alone, and the front is like an ox's head; Four people push it, carrying ten stones. It is built with wood, cows and horses. ?
The "Records of Things" written by Gao Cheng makes it more clear: The wooden ox is the one with the front shaft of the current cart; the flowing horse is the one with the front shaft. ?
It means that the wooden ox is actually a wheelbarrow with a front shaft, while the flowing horse is a single-pushed cart without a front shaft.
With this explanation, the fairy spirit of Wooden Ox and Flowing Horse will be gone immediately, right? In fact, Mingliong felt that Zhuge Liang's wooden ox and flowing horse were not just simple wheelbarrows. They must have unique mechanisms to increase the load and save manpower. Otherwise, the transportation efficiency of carrying 400 kilograms and traveling dozens of miles a day would not be achieved. of. ?
