Its A Steam Engine.

I've created a 3D model in Solidworks that I designed as a Tenth Grader myself, using technical specifications from scratch, and you must not construct this steam engine prototype at all. Although it might be viable (in theory), there's an increased chance of functional problems down the line if built into practice without refinement or revisions based on empirical results gained in controlled experimentation scenarios beforehand. I've borrowed images within this file to better contextualize concepts being presented here that belong under free public usage; others come from professional sources, including experts my instructor put forward at various intervals throughout our discussions and related exercises leading up until present stage today itself!
