But dear expert u didn't mention about where the demand for mechanical power needed... For example it most certainly for mass production,.... Thn for uniform productions,... Etc... Plz I want a systematic answer... 🙏 so answer the question once again with proper systematic

In countries with labour shortage, industrialists were keen on using mechanical power so that the need for human labour can be minimised. This was particularly the case with America which faced severe labour shortage. Machines were also needed to produce goods for a large markets. For example uniforms and standardised goods were mainly produced by machines.
