Platform scale was used to gesture the weight of an object or person. It’s used in hospitals, factories, for trucks and for people to buy. its helpful for trucks incase weight limits. For example, a truck is moving to a city but there’s a weight limit of trucks. He goes to a limit holder to make sure he can pass in the city. How do you think it was used back then or how it was made? Well, Romans and Greeks made this for rocks to move to see where to build it without it we would have no clue and might even be in danger. Without platform scales it would be danger in the world.
The Railroad T-rail would be for trains moving cargo, people or food. It’s also used for trains if they need to switch tracks, which a company made so trains could be more, safe. it was made by Robert Stevens its now helpful for people to travel safely across the city.
The mechanical reaper used to cut crops without doing the hard work. Now cuyres father tried making this but it was too hard for him. Cuyres tried making it simpler and he made it with friend’s help. Now it’s used in farms. There is a blade in the back of the farm machine to harvest the crops. Then you have horses pulling you in a carriage while it all harvests. (Fun fact the machine while it was working most of the crops would already be harvested meaning your harvesting millions of crops a day)
