- Lesson 57: Distilled Spirits
- Lesson 58: Vertical Windmill
- Lesson 59: Stern-Mounted Rudder
Trebuchet
The trebuchet is a missile launcher. It uses gravity or other force to launch.
Here is how the trebuchet works:
- 1: men pull ropes or crank a pulley to make force pulling one end of the trebuchet down (above) Note that the picture pulls down on the projectile, whereas it is actually on the other end.
- 2: The rope is released(, or in a crank, it is stopped and then is released by a button or switch of some sort) and the force is stopped.
- 3: The projectile flies!
Distilled Spirits
Ups and Downs
Ups
- Spirits make you happy. You feel great.
- It is easier to transport. Sailors can carry more Distilled Spirits than can water.
- It doesn’t taste bad after a little while, compared to water.
Downs
- One of the Distilled Spirits is rum. Rum was made in New York, in the time of the colonies. Slaves were bought from Africa, brought to the Caribbean islands to grow sugar canes, and then the sugar canes were sent to New York and made into rum. Then the slaves were sent to the colonies and helped cause the civil war.
- Getting drunk is good until you get too much. When you get too drunk, you make bad dissensions like (in the modern day,) driving a car.
Vertical Windmill
Water wheels were a prime source of energy before the Windmill. The windmill is used to harness power of motion from the wind.
They are used to grind flour to make bread and other similar uses.
Rudder
Rudders are attached to the back of a boat for steering. If you turn it a little bit, you steer. If a lot, you won’t get any luck, and may sink.
