Redneck Builder: Understanding Engineering Principles Without Formal Education

[Beretta926]

How did you find PF?

Google search

I saw it was a responsive group and knew it would be helpful. No money to buy textbooks for formulas and Google is often maddeningly unhelpful or worse, misleading.
Thanks in advance for your patience as I have ZERO formal education in the subject of physics and very little in engineering. Because of this my terms will be wrong and sometimes confusing and/or totally wrong
