Chapter 181 Small pulley, big power, 42 gold
The next day, Li Yu'er and his sister first delivered the whale bones to the wooden man Zhang, and then went to the blacksmith shop to pick up the pulleys and iron wheels that had been custom-made.
“The stuff is well made, worth the price.”
Li Yuer made the parts of the pulley separately, so it would be a waste of effort if you don't know how to install them.
Li Yuer carefully checked the quality of the thing. Although it could not be compared with the steel of later generations, its hardness and polishing process were good and it was fully capable of handling the workload.
Li Erlang picked up the pulley and compared it with the iron wheel, and asked curiously: "What is this? It looks like a wheel, but it's not a wheel."
Li Yuer pretended to be mysterious and said: "This is a good thing. You will know when the time comes. With this treasure, people can move things several times their own weight just like ants."
"Is it true? That's it?" Li Erlang looked at the pulley carefully again, but he couldn't imagine how this thing could help people move things?
It has no hands or feet and is so small, how can it help people carry things that are several times heavier?
Could it be some kind of magical instrument that could give me divine power just by chanting the spell?
Li Yuer put away the pulley and said with a smile: "When we get home, I will assemble it and show it to you. Then I will need you to make a few wooden racks. However, we have to buy some carpenter tools now."
The use of the pulley requires a fixed point. Li Yuer plans to make a few sturdy wooden racks. These things are simple and easy to make, and can be made according to the detailed drawings she drew. In order to keep it confidential, she plans to let the men of the Li family make it themselves.
Back in Fushui Village, Li Erlang urged Li Yuer to try out the pulley quickly.
Li Yuer said angrily: "Why are you in such a hurry? You can't run away. Go find a bundle of thicker hemp ropes and call everyone over. You know who everyone is referring to, right?"
Li Erlang thought for a moment and said, "I understand."
Soon, Li Laosan’s brothers, Dalang, Mei’er and others arrived.
Li Yuer didn't beat around the bush. He picked up the pulley and rope and started to install them: "You have to watch carefully. I will install it once, and you will have to install it by yourselves in the future."
"What is this?" Li Dalang asked curiously.
Li Yuer explained as he installed it: "This is called a pulley. I figured it out when I was bored. We saw people unloading cargo at the dock before. It was so heavy that it would be difficult for several people to pull it. But with this little thing, one person can pull several times his own weight."
"Wow! This is so magical!"
Li Yuer fastened the rope and pulley and said, "Brother Jiaqueer, go get a basket that can hold a person."
There wasn't much else in the countryside, but there were plenty of baskets, and they were soon found.
Li Yuer threw one end of the rope tied to the pulley over the branch of the old locust tree and let it hang from the other end of the branch.
"Brother, tie the rope to the basket, tie it on both ends, so that the force is balanced."
The two have been working together for a while and have developed some tacit understanding.
"I see. You are planning to hang something, right?"
Everyone else gathered around and watched carefully, afraid to miss any details and not embarrass themselves in the future.
Li Yuer put the pulley onto the rope, with one end in Li Yuer's hand and the other end tied to the basket.
"One of you goes to the basket."
After discussing for a while, everyone decided to let the lighter house sparrow in.
The house sparrow found it very interesting and swiftly sat in the basket.
Li Yuer smiled and looked at everyone, "Watch carefully, I am going to pull Brother Jia Que up now."
"Wait!" Li Dalang was worried that she would hurt herself. After all, she was only nine years old. He quickly said, "Let me do it. I'm stronger."
Li Yuer smiled and shook her head, "Don't worry, Brother Dalang, just wait and witness the miracle."
Li Yuer grabbed the rope and kept pulling, and soon the basket was pulled off the ground.
Everyone looked at this scene in amazement and could hardly believe their eyes. The nine-year-old Li Yuer actually pulled up the thirteen-year-old house sparrow.
"Oh my God! Li Yuer, are you so strong?" Li Erlang exclaimed in surprise.
Although Jia Que'er was the lightest among them, he still weighed about 100 to 180 kilograms. Li Yu'er was only nine years old. How could he have so much strength to hang someone up?
That’s not all. Li Yuer could continue to pull the rope, and the basket rose higher and higher, more than two meters off the ground.
Li Yuer said proudly: "See? This is the power of the pulley. Not only that, the pulley is more suitable for transporting goods in places with a large height difference."
Li Laosan was surprised and curious, so he wanted to try it himself, "Yu Baoer, let Uncle San try it!"
Li Yuer slowly put the sparrow down and then handed the rope to Li Laosan.
Li Laosan was very brave and quickly pulled the sparrow up.
The sparrows were so frightened that they kept shouting, "Brother San, please show mercy! Please show mercy!"
"Hahahahaha!"
Everyone was laughing below, and Li Erlang was just watching the fun and said, "Don't worry, Jiaque'er. This old locust tree is very strong. You won't fall. It's my turn! It's my turn now!"
So, as soon as the sparrow was put down, Li Erlang lifted it up again.
He cried miserably, "Put me down! Put me down! We can't just pluck the wool from one person!"
"Hahahaha! It's okay, House Sparrow, you're not a sheep, you won't be bald!"
Li Meir also joined in the fun. She took the rope from Li Erlang and lifted the sparrow up.
The sparrow was still shouting, "No! Change people! I want to play too! This is not fair! You are bullying the honest people!"
Their laughter attracted other people, and Old Man Li joined in like a naughty old man.
Jia Que'er said quickly, "Grandpa Li! Good Grandpa! Can you let me come down first and let someone else take over?"
Old Man Li thought about it and said, "Okay! Third Brother, you go up."
"Me?" Li Laosan pointed at himself and said, "I'm too heavy, the rope will break easily!"
Li Yuer said, "It can't be stopped. How about you and Brother Jia Que'er come together?"
At this point, everyone was shocked, "Can two people do it?"
Li Laosan was brave and a little skeptical, so he really went up. After all, he would not get hurt if he fell from a height of one or two meters.
"Let me see if you can pull us up."
Jia Que'er looked at Li Lao San with emotion: "Third brother, you are a real brother!"
As a result, Old Man Li quickly promoted the two of them.
"Awesome! Awesome!" Datou's eyes lit up, "Yu Baoer, how many pounds of stuff can this pulley pull?"
Li Yuer said: "You got the point. The pulley is like a seesaw. How much it can pull depends on the weight of the objects on the left and right. A person weighing 100 kilograms can pull up a weight of about 200 kilograms. If the pulley is designed more delicately, it can pull up more things.
This is also related to the length of the ropes on the left and right sides of the pulley, as well as the support point and the mass of the pulley. At present, our pulley can easily pull up twice the weight. "
Big Head exclaimed: "This is great. Can pulleys be installed in wells in the future? This way, it won't be so hard to draw water."
Li Yuer nodded and praised: "Big Head Brother is really smart. He can draw inferences from one example."
Seeing that he was eager to learn, Li Yuer introduced other uses of the pulley: "The pulley can also change direction, making it easier to move goods at different distances and angles. There are also movable pulleys and static pulleys, and they can be used in combination. Big Head Brother, observe and study more in the future, and you will find more wonderful uses."
Datou happily watched them pulling people to play, but he silently memorized the pattern in his heart.
