Answer:
The best answer to the question: Why did Whitney consider standardized parts, would be: he wanted to achieve an increase in the mass production of guns.
Step-by-step explanation:
Eli Whitney is best known for his invention, at the age of 27, of the cotton gin machine. With it he made it possible for mass production of cotton in the U.S and made U.S cotton really competitive in international markets. However, he is also known for his venture into gun-machine production in the 19th century, as the U.S considered the possibility of entering war with France. The idea of standardized parts in gun-machine production had already been proposed by a French and an English inventors, but Whitney capitalized on it, and in doing so he was able to ensure that his unskilled workers, and he himself, who had never had experience with gun production, could meet the demands of the U.S government. With the use of the idea of standardized parts, Whitney was able to accomplish this multiplication of production in guns.
