Essay / James Watt Micrometer for Durability - 539
DurabilityTo assess the durability of an artifact such as the James Watt Micrometer, a number of conditions should ideally be observed. As part of the research procedure, our group identified the following conditions:• Component materials• Product limitations and life expectancy• Environmental effects• Economic effectsThe remainder of this section will present our findingsComponent materialsThe James Watt's micrometer is made only of two metal alloys, namely brass and steel. These two alloys are well suited to the construction of this type of tool at the time of its creation. Brass and steel were readily available in the UK during the Industrial Revolution, with major brass factories in Swansea and large steelworks in Sheffield. Having domestically sourced materials will certainly have made these alloys a cost-effective choice for micrometer construction. Both alloys are suitable for tooling, machining and shaping, while having excellent strength and durability properties. Other materials available at the time, such as tin and iron, would likely not have been favorable because they were either difficult to shape precisely or simply did not possess the strength properties of the chosen materials. It is also worth noting that brass and steel have great recycling advantages. Naturally, this may not have been a deciding factor in the choice of materials during the Industrial Revolution. Nevertheless, both alloys can be heated to the point that they can be returned to the molten state and reformed into raw construction billets ready for future use. Product limitations and life expectancy. The chosen artifact may have certain limitations, such as the fact that the tool is not versatile for example. it can only be used to measure objects; It can only measure objects that fit into the "U" shaped jaws or measuring area. Apart from these limitations, the micrometer is a tool that perfectly serves its purpose. This leads us to believe that it may have been used well after new models such as the Whitworth micrometer came onto the market. For example, let's say you have a tool that you use daily and that tool is in perfect working order. Just because a newer version of that same tool hits the market doesn't mean your everyday tool becomes obsolete. There are many factors to consider when choosing a newer tool; Even if you purchase the newer version, it does not necessarily mean that the older version will be discontinued. As the micrometer is still on display at the Science Museum in 2013; in what appears to be astonishing condition for an artifact over 240 years old, testament to James Watt's ingenious choice of materials.
