In this case, explosives would be needed through a method called “blasting”. Sometimes iron ores are found in ‘taconite’, which is a sturdier type of iron formation this is more difficult for a pickaxe to deal with. Using the pickaxe, the kinetic energy from a person would transfer into the tool along with gravitational energy from the earth to create a force strong enough to strike against the ore for harvesting. As humans can not harvest something as solid as the metal from the ground with their bare hands, they would require a specialized tool like a pickaxe. Humans are prime movers, so they output kinetic energy to create work. There are many methods for harvesting iron ores, but the two main ways are using human labor or using explosives. In order to acquire iron ores, it would need to be harvested from the ground. Iron ores are the first raw materials required for the production of paper clips. Paper clips are made through long processes of both physical and chemical changes. The aspects of the paper clip’s life cycle include different forms of energy used in the galvanization process of steel, strengthening of the steel, physical processing, global mass production and distribution, and recycling. Paper clips require a large sum of embodied energy in their production process. It may seem that it is a very simple object and that it is very simple to manufacture, but it actually goes through a long process of energy usage. It is a necessary supply to normally bind paper together. Paper clips are everyday objects used in households, offices, and schools.
