Inventions during the Han Dynasty
Some important inventions during the Han Dynasty were the wheelbarrow, seismograph, paper, and cast iron tools. The wheelbarrow is used for yard work making it easier to carry around loads and move them from place to place. It has a box in the middle of it to carry the load. It has a wheel on the bottom to allow the wheelbarrow to move about with little effort. There are also handles on the end of the wheelbarrow allowing you to get a grip of it with ease. It also has two pegs on the bottom to allow the wheelbarrow to support the load by itself.
The seismograph is used as a tool to measure the magnitude of an earthquake. There is a little pen on the end of a string and every time the tectonic plates move it causes the pen to make spikes on a piece of paper. The bigger the spikes the greater the magnitude of the earthquake.An earthquake is caused by movement of the plates under the surface of the earth. There is tension between all the plates and when the tension is released and the plates move it results in an earthquake. The scale that is used to determine the strength of the earthquake is called the rictor scale. It has measuring system in which the lowest magnitude is 0.1 and it is a never ending scale. There is no set measurement that indicates that it has raeched the strongest magnitude and can not go any higher.
Paper is used for so many things today including writing, money, homework, art and many other things. Paper is made from trees and is very important in the lives of people today. Cast iron tools are used in workshops and they give the user an easier way to build things and shape things. There were many inventions during the Han Dynasty and all of them play a big part in our lives today.
