10. Why did the flying shuttle require the invention of the spinning jenny?

The flying shuttle (John Kay 1733) had increased yarn demand by the weavers by doubling their productivity, and now the spinning jenny could supply that demand by increasing the spinners' productivity even more. The machine produced coarse thread.

Explanation:

The flying shuttle was one of the key developments in the industrialization of weaving. It allowed a single weaver to weave much wider fabrics, and it could be mechanized, allowing for automatic machine looms. It was patented by John Kay (1704-c. 1779) in 1733.
