This week I learned about the Platform Scale, the Railroad T-Rail, the Multi-Coil Magnet, and the Mechanical Reaper.
The Platform Scale is a scale that measures how heavy an object is. There is a weight attached to the Platform Scale when an object is placed on the platform one must balance it out, once it is balanced the gauge will tell how much the object weighs. It impacted history because one could see how much they weighed and figure out how much they have grown.
The Railroad T-Rail is the rail along the tracks. It is called the T-Rail because it looks like an upside down T. The reason it looks like an upside down T is because it is a very sturdy shape, which can hold a lot of weight. That means that the train can go faster.
The Multi-Coil Magnet is iron wrapped in insulated wire many times, the more wire the stronger the magnet. Without the Multi-Coil Magnet the telegraph machine would not be possible.
The Mechanical Reaper is a machine that is pulled by horses or tractors. The machine has a big knife that cuts wheat then tosses it aside in bushels. This significantly decreased the time it took to cut the field of wheat. Because of that, one could grow more wheat. That made wheat more available so the prices of things like flour and bread went down.
So the Platform Scale, the Railroad T-Rail, the Multi-Coil Magnet, and the Mechanical Reaper are the inventions I learned about this week. Without these inventions life would not be very easy at all.
