Thinking that the four particularly large sites of the Kingdom of Bohemia, the Kingdom of Hungary, the Principality of Silesia and the Principality of Moravia are about to miss their homes, Marin is very depressed.
At night, Marin tossed Angela hard and asked for several times. Angela lingered Marlin gasping after the incident, and asked suspiciously:
"My dear, why are you so excited today? Almost tossing people to death ..."
Marin did not hide him, and said his thoughts. Angela's eyes shone brightly. You know, that's four big countries. Moreover, the Kingdom of Bohemia is the head of the four secular electors of the Holy Roman Empire.
So Angela said brightly:
"Otherwise, let's let Caesar marry Anne of Bohemia? That's the King of Bohemia! After he's up, he's an elector!"
Marin shook his head, not to mention that the Kingdom of Hungary was a gunpowder barrel area. Simply not relying on the sea and not suitable for the development of a large voyage is far worse than the United Kingdom.
Moreover, his territory is only a short distance away from the United Kingdom and the North Sea. If you get the Kingdom of Bohemia, the Kingdom of Hungary, Silesia, and Moravia, not to mention the problem of warfare there, that is too far from East Friesland, separated by thousands of mountains and waters, it is not easy to manage, but also A big problem.
However, for the British plan, Marin did not tell Angela to avoid Angela's sloppy mouth and accidentally said it.
Then, Angela felt that it would look good to let her second son be a Bohemian king and elector. So, she took the initiative to rush up, entangled Marin ...
Marin said, crying:
"It's impossible for a woman to get pregnant with a man and a woman. Because your mouth is facing down, the liquid drains directly."
"Then you go up and down, I'm going to have a son to be king and elector of Bohemia!" Angela said stubbornly.
Marin was very speechless, but still pressed his face ...
The next morning, Marin felt a sore waist, and his body was very deficient. He rubbed his waist while mumbling:
"No wonder the emperor of Huaxia died early. Kang Mazi became the emperor for 61 years, and he was considered to have been in power for a long time. Moreover, it was because of his 8-year-old enthronement ..."
"Huh ... No, his grandson Qianlong is also very uproarious. Not only is there a pile in the palace, but there is also a Rongma (Xia Yuhe) **** horse by the Daming Lake ... Why can he live to 89 years old? He has an ancestral recipe? Well, he still has to send someone to Daming to find such an ancestral recipe ... "
Anyway, Marin found that after he passed through, he didn't get any strengthening except for his brain memory. You can't fight ten one at a time, and you can't count women all night ...
In short, he is still a normal body. However, after long-term exercise of martial arts, the body is stronger than the average person. As a normal man, the number of nights is increased, and it is inevitable that there will be back pain and footsteps ...
Rubbing his waist, stepping on the "space step" (not MJ's dancing space step, it is Armstrong's light and fluttering space step, it looks like the footsteps are staggering, authentic space step ...), Marin came to the palace The office of the hospital began to process important documents ...
Soon, Jeffrey suddenly came to Marin's office and invited him to attend the road completion ceremony ...
"Road completion ceremony? Do you want me to participate in such a small thing?" Marin was surprised.
Jeffrey was also somewhat surprised, so he asked rhetorically:
"Master Duke, didn't you make me pay special attention to the construction of that ash (cement) road?"
"Volcanic ash?" Marin froze for a moment, then suddenly reacted:
"It turned out to be a cement road ... well, I'll go right away. Go and prepare the carriage and guards!"
Soon, the four-wheel spring shock-absorbing carriage was ready, and Malin and Jeffrey rode into the carriage with a highly protective tinplate covered with tinplate. And around the carriage was full of sturdy guards wearing chest armor.
Under the guard of a large number of guards, Marin's carriage quickly reached the edge of the cement road outside the north gate ...
After getting off the bus, Marin saw a neat and smooth rural cement road, which was similar to the cement road of the later Marin home.
This is a standard rural cement road 3.5 meters wide and 20 centimeters thick. Moreover, on the cement pavement, Marin made people cut every few meters, said to prevent the pavement from expanding or shrinking.
In fact, the fly ash cement used in Malinpu cement road is a kind of cement with low expansion coefficient and good crack resistance. It's also because Marin has built a salt cooking base, otherwise, there is not so much fly ash supply yet. In later generations, the ordinary cement road uses the simplest Portland cement. Only reservoirs, coastal defense, river defense and other projects will use cement such as fly ash cement with good waterproof and anti-corrosion properties.
Fly ash cement is used for paving the road, and the rural cement road is only 3.5 meters wide. Of course, after the knife is better.
In addition, the cement pavement is not smooth. Otherwise, on a rainy day, people can "skate" on the concrete pavement. On the cement pavement, the construction staff flicked many shallow bars with thin lines. Although the depth is very shallow, the friction coefficient of the cement pavement has been improved a lot, but the friction is not high compared to the dirt road. The most important thing is that with this very shallow "bar", even if it rains, the concrete pavement will not slip.
In fact, this cement road was repaired more than a month ago. However, the concrete pavement needs to be air-dried. So, after waiting for more than a month and waiting for the concrete pavement to dry completely, I invited Jeffrey to accept it.
Jeffrey remembered that Marin had said that this path was very important and asked him to follow up in person. Obviously, this road is very important for Marin, so he invited Marin to participate in the road completion ceremony. Well, this kind of ceremony was also invented by Marin ...
The so-called road completion ceremony was actually for Marin to unveil the card, and then personally ride the carriage back and forth on the road.
Marin gladly put his carriage on this small cement road that was only 3 kilometers long ...
After entering the cement road, the carriage quickly accelerated. On such a flat concrete road, the carriage ran fast. Later, after the car got up at speed, it basically didn't need much effort from the horse, and drove directly on the road by inertia. Even if the horse wanted to stop, it was pushed forward by the car behind ...
If the horse pulling the cart can speak at this time, the horse will certainly say:
"My mother, I can't stop!"
The horse ran desperately. If it slowed down, the carriage behind it actually pushed the horse forward. It seemed that the horse was not allowed to slow down. This made the horse very depressed, so he kept running. Fortunately, under inertia, the horse cart was not too hard at this time. Unlike those mountain roads with high resistance, Mabula can't move the car.
Soon, more than three kilometers of cement road came to an end. However, at this time, the speed of the horse and the carriage reached a very high value. The horse wanted to stop but was pushed back by the carriage and continued on ...
Fortunately, European carriages have brakes. When the driver saw the end of the road, he quickly braked manually. The brake is on the left, a simple lever principle-the front is the long arm, which extends to the left hand side of the driver. At the back is the short arm, and there is something with a lot of friction at the top. There is no rubber right now, the friction is made of leather.
The driver raised his long arm with his left hand. The leather friction pad leaned on the wheel and rubbed against the wheel. He wanted to stop the wheel by friction. However, unlike the brake pads of later generations on the inside of the rim, the brake pads at this time are actually on the outside of the wheel, and the friction is also on the outside of the wheel ...
At the same time, the driver's right hand also began to pull the reins and control the horses to stop ...
It is a pity that the carriage was running too fast this time. Not only was it difficult for the horses to stop due to inertia, there was also a very harsh brake sound from the wheel side-no way, who called the carriage too fast ...
Fortunately, the lake and cliff are not in front. Some distance after the year on the dirt road, the carriage stopped. The driver was so scared that he repeatedly asked Malin for guilt. After all, this was a serious mistake.
Marin did not blame the driver, because he knew that people of this era had underestimated the convenience of the cement road. Therefore, there is nothing wrong with the mistake. Moreover, I didn't have a problem.
At this time, Marin's attention has been completely attracted by this rural cement road that has been leading the century for hundreds of years. Just now, he clearly felt that the carriage threw the highest speed ever. Although they still can't catch up with the cars of later generations, they can certainly catch up with the battery cars. In the previous life, Marin was able to reach the speed of 26 yards by riding that used battery car. This time the carriage was on the cement road and it almost ran out of the speed of the electric bike.
In this era, even on the relatively flat Roman Avenue, the carriage speed rarely surpassed 20 kilometers per hour. That is because there are uneven areas between the stones on the Roman Boulevard, which increases the friction and also causes a small vibration of the car. Therefore, the horse-drawn carriage generally does not exceed 20 kilometers per hour. Of course, if you encounter a Ferrari-level horse-drawn horse and run hard, you can also break through this speed, but it is rare.
But on the rural cement road ~ www.novelhall.com ~ even ordinary carriages can easily run more than 20 kilometers per hour. The only problem is the brake problem.
Marin intends to let people study the simple foot brake system for future generations, so that the carriage driver will not brake with his left hand and the reins with his right hand.
Moreover, Marin found that when the 3 km road ran down, the horse pulling the cart was not tired at all, and he was very spiritual.
It's no wonder that after the speed of the carriage is raised on the cement road, the inertia of the carriage and the small coefficient of friction on the road surface make the force required by the horse to pull the carriage much smaller. On the contrary, when horses want to slow down, they are often pushed forward by the inertia of the carriage. Therefore, horse-drawn carts, walking on cement roads, save a lot of effort than on dirt roads and cross roads. As a result, the distance that the carriage continues to travel is much longer than on other roads. As a result, the average distance that the carriage rides every day will also increase a lot. Even, it is not a myth to double it.
The ordinary carriage can run 100 kilometers a day on ordinary roads, which is great. Because, after running for an hour, the carriage must stop and rest. Not for people to rest, but for horses. Otherwise, the horses will be exhausted. In the Roman era, on the Roman Boulevard, the coaches only ran 160 kilometers in 24 hours, and had to rest and change horses halfway. Otherwise, the horses can't eat it.
On the cement road, the horse pulling the cart has less power, the rest period becomes longer, and naturally it can run farther. It is not a myth if you drag your horse for 200 kilometers a day on a cement road if you can pull your horse better. If it is a double horse-drawn carriage, the speed should be faster. Of course, this is a manned car. If it is a heavy-duty truck, the speed will be much slower ... after all, the horse's pulling force is far behind the machine ... The average car has more than 100 horsepower, which can withstand hundreds of horses ...
