The program is brought to you by the world's most famous engine, the Oga-ma century. In 1911, the first small engine was released in Japan and was exported to the United States. In the 13th century, the engine was developed. In the next 40 years, the small engine was developed. It is still on the road. The world of small engines is already leading. The Oga-ma century is coming. Today, we will introduce you to the science of the world of small engines. Today, we will talk about the research of Professor Morio Miyagaki, Professor Atsushi Iwata, Professor of Education at Kobe University. Professor Iwata is the former captain of the Niraima High School, a prestigious school in Koshien. I would like to ask Professor Miyagaki about the science of small engines. Recently, there have been many small engines. When you look at the high school you can see that the home run is getting more and more. What does that mean? There are some things that are reversed about nine times. The biggest change from wooden bat to metal is the change in the size. When you use a metal bat, the home run comes out. Why was it used? First of all, the ball flies well. It is fun to play baseball. The feeling of hitting the ball is also good. The sound of metal is loud. I can't say anything about that. The biggest change in baseball is the economic aspect. It doesn't cost money. Wooden bat is cheaper. It is longer than cheap. If it is wood, it will break. In the case of metal, it will never break. Can it be used permanently? It is almost permanent. It is a little big. Do you know the difference between thick and thin? The thick one is thicker. The thin one is thinner. What about wood? There is no wood. There are some parts that are bent at the tip. The wood is stuck inside. This is a stick. It is cut like this. In the case of metal, it is compressed. The thin one is thicker. What is the difference between wood and metal? The weight is centered. The center of gravity is not bent. This is the center of gravity. What is the difference between wood and metal? The center of gravity is closer to the base of the stick. The center of gravity is closer to the base of the stick. The difference is 5 cm. The center of gravity is closer to the base of the stick. The weight is distributed throughout the stick. The center of gravity is closer to the base of the stick. How does the ball rotate? The ball is centered on the base of the stick. The weight of the stick is related to the weight of the ball. The grip position is the distance from the end of the stick to the base of the stick. The distance from the end of the stick to the base of the stick is 5 cm. The distance from the end of the stick to the base of the stick is 5 cm. The distance from the end of the stick to the base of the stick is 5 cm. The difference between the vertical and horizontal changes is also large. The distance from the end of the stick to the base of the stick is 5 cm. The distance from the end of the stick to the base of the stick is 5 cm. The distance from the end of the stick to the base of the stick is 5 cm. The distance from the end of the stick to the base of the stick is 5 cm. The distance from the end of the stick to the base of the stick is 5 cm. The distance from the end of the stick to the base of the stick is 5 cm. The distance from the end of the stick to the base of the stick is 5 cm. The distance from the end of the stick to the base of the stick is 5 cm. The distance from the end of the stick to the base of the stick is 5 cm. The distance from the end of the stick to the base of the stick is 5 cm. The 4-cycle engine friendship competition held in Nagaragawa, Gifu on September 15, has been completed successfully. In the future, we will deliver other information about the models in this OS information corner. People have been dealing with various machines since ancient times. Eventually, the steam locomotive was born and traveled the world. OS, which has continued research on the Taimanu, has been loving the steam locomotive for 50 years. This program was brought to you by Live Steam OS, a provider of the Ogawa Seiki.
